In the following, "online" means that the terminal 20 can communicate with the server 10, and "online state" means this online state. Further, "online payment" means that payment is performed by the server 10 in the online state.

In the following, communication between the terminal 20 and the server 10 is not limited, and as an example, a frequency band different from wireless LAN communication, which is realized via a base station or the like installed by a communication company (communication carrier), is used. It will be realized by the first communication method used. The first communication method includes, but is not limited to, packet communication (so-called mobile data communication in the terminal 20) as an example.

Further, as the communication method, a second communication method different from the first communication method may or may not be used. The second communication method includes, but is not limited to, a wireless LAN (for example, WiFi (registered trademark)) as an example.

FIG. 3-1 is a flowchart showing an example of the flow of processing executed by each device in this case. From the left side, an example of a process executed by the control unit 21 of the terminal 20, a process executed by the control unit 51 of the store code reader device 50, and a process executed by the control unit 11 of the server 10 is shown.

Each step in each process is indicated by a combination of uppercase letters and numbers, and the term "step" is omitted herein.
Further, the flowchart described below merely illustrates the processing in this embodiment, and in the flowchart described below, some steps may not be executed or additional steps may be inserted.
These also apply to the other flowcharts herein.

First, the control unit 21 transmits the code generation request information for requesting the generation of the terminal display code to the server 10 (via the communication I / F22) by the communication I / F22 (A110).

In the following, as an example, not limited to, "code information" means information stored in a code image by encoding or the like or information stored in a code image (hereinafter, "original" in the sense of original information. It will be described as a concept including "information") and a "code image" in which the original information is stored. That is, the "code information" includes the "original information" and the "code image".
The "original information" may or may not be expressed as "encoding information", "stored information", or the like.

Further, in the following, as an example rather than a limitation, the term "code" has substantially the same meaning as "code information".

However, these definitions are merely examples and are not limited to these.
For example, the term "code information" may or may not be used to mean "original information".
Further, for example, the term "code" may or may not be used to mean "code image".

In this embodiment, as an example of the above-mentioned original information, a number uniquely generated by the server 10 for each terminal 20 of the source of the code generation request information or for each user of the terminal 20, and having a predetermined number of digits. An example is a "payment number" which is a random number. The payment number is information associated with the terminal 20 or the user of the terminal 20, and can be said to be information used for payment by the server 10.

In the following, the payment code generated by the server 10 based on the code generation request information will be referred to as a "terminal display code", and the code image of this terminal display code will be referred to as a "terminal display code image".

Although the details will be described later, the above payment number is stored in the terminal display code image.
The terminal display code image and the payment number are examples of "first information" for making a payment using the code image, and are transmitted from the server 10.

In the following, a case where the information for requesting the server 10 to generate the above-mentioned terminal display code image is used as the code generation request information will be illustrated. That is, in this process, the generation of the terminal display code image is requested from the terminal 20 to the server 10 as an example, and the A110 requests the server to generate the code generation request information for requesting the generation of the terminal display code image. Send to 10.

Further, in the present specification, the "terminal display code" will be described as a code used for payment in the payment type "terminal code display".
In the payment type "terminal code display", when the user of the terminal 20 makes a payment at a store or the like, the terminal display code image displayed on the terminal 20 is displayed on the store by using the payment application stored in the terminal 20. Present it to the clerk at the code register 60. Then, the settlement is realized by having the store code reader device 50 or the like read the code image for terminal display.
Since the terminal display code is a code (code image) presented by the user of the terminal 20 to a clerk of a store or the like, it can also be expressed as a "presentation code" or a "user presentation code".

The code generation request information transmitted by the A110 may include, but is not limited to, identification information for identifying the terminal 20 or the user of the terminal 20 as an example. For example, terminal identification information for identifying one's own terminal 20 (for example, terminal ID), user identification information for identifying a user of one's own terminal 20 (for example, user ID), account information for a payment application (for example, application ID). Etc. are included in this.

When the code generation request information is received from the terminal 20 by the communication I / F 14 (C110), the control unit 11 performs the terminal display code generation process (C120).

Specifically, as an example, not limited, a random number with a predetermined number of digits is used by using a method (algorithm) for generating a random number with a predetermined number of digits (for example, about 10 to 12 digits). Is generated as a payment number. Then, as an example, not a limitation, a terminal display code image including at least a payment number as original information is generated. More specifically, at least the payment number is encoded (encoded) and graphicized (imaged) to generate a terminal display code image represented by a two-dimensional code (for example, QR code) image. Further, the identification information of the terminal 20 or the user of the terminal 20 included in the received code generation request information is associated with the generated payment number and stored in the storage unit 15.

Next, the control unit 11 transmits the generated terminal display code (terminal display code image in this example) to the terminal 20 by the communication I / F 14 (C130). The terminal 20 receives the terminal display code (terminal display code image in this example) from the server 10 by the communication I / F 22 (A130). In this case, the control unit 21 causes the display unit 24 to display the received terminal display code image as an example, not a limitation.

After that, when the terminal display code image displayed on the display unit 24 is presented to the store clerk or the like by the user of the terminal 20, the control unit 51 displays the terminal display code on the display unit 24 of the terminal 20. Control is performed so that the code reader 58 reads the image (B150).

After that, the control unit 51 accesses the server 10 by the communication I / F 54 using the application interface (API) or the like associated with the payment application provided (distributed) by the payment service provider, and at least reads the server 10. The payment number obtained by decoding from the terminal display code image, the identification information for identifying the store or the store code reader device 50 (hereinafter referred to as "store identification information"), and the amount to be settled (hereinafter, referred to as "store identification information"). The settlement request information including the "scheduled settlement amount") is transmitted to the server 10 by the communication I / F 54 (B160).

When the payment request information is received from the store code reader device 50 by the communication I / F 14 (C160), the control unit 11 performs the payment process (C170). Specifically, it is determined whether or not the payment number included in the received payment request information is stored in the storage unit 15 in association with the identification information of the terminal 20 or the user of the terminal 20. Then, if it is stored, it is determined that "payment is possible", and the balance of electronic money of the terminal 20 or the user of the terminal 20 identified from the identification information stored in association with the payment number (application of the payment application). Settlement is performed by subtracting the planned settlement amount from the balance of electronic money associated with the ID (hereinafter, simply referred to as "balance").

After that, the control unit 11 transmits a payment completion notification for the store (hereinafter, referred to as “store payment completion notification”) to the store code reader device 50 by communication I / F 14 (C180). The store payment completion notification includes, as an example, not limited to, the fact that the payment has been completed (successful), the date and time of the payment (settlement date and time), and the payment information for the store such as the payment amount (settlement amount). ..

Further, the control unit 11 transmits a payment completion notification for the terminal (hereinafter, referred to as “terminal payment completion notification”) to the terminal 20 by communication I / F 14 (C190). The payment completion notification for terminals is not limited, but as an example, the fact that the payment has been completed (successful), the date and time of payment (settlement date and time), the store identification information of the store that settled (payment store identification information), and the amount of payment (payment amount Includes payment information for terminals such as payment amount). Then, the control unit 11 ends the process.

Here, when the payment by the server 10 is successful, the payment completion notification for the store and the payment completion notification for the terminal are transmitted from the server 10, but the server 10 makes the payment due to insufficient balance or the like. You may not be able to do it. In this case, the notification that the payment could not be made (for example, the payment error notification, the payment NG notification) may be transmitted to the store code reader device 50 and the terminal 20.
The same applies to other processes.

When the store settlement completion notification is received from the server 10 by the communication I / F 54 (B180), the control unit 51 ends the process.

Further, when the terminal payment completion notification is received from the server 10 by the communication I / F 22, the control unit 21 updates the balance stored in the terminal 20 as the payment application data based on the received terminal payment completion notification. To do. Further, the control unit 21 causes the display unit 24 to display the payment result (A190). Then, the control unit 21 ends the process.

FIG. 3-2 is a diagram showing an example of a top screen displayed by the payment application executed by the terminal 20.
This top screen is a display screen displayed when the payment application is started, and the name of the payment application "Payment APP" is displayed at the upper part of the screen. The balance (here, "3000 yen") is displayed in the frame below it, and a charge button for charging (adding) electronic money is displayed next to it. Below that, a plurality of function icons corresponding to various functions of the payment application are displayed.

Among these function icons, the icon indicated as "code" is not limited, but is, as an example, a "code icon" for displaying the code display screen on the display unit 24. When this code icon is touch-operated by the user of the terminal 20, the code generation request information is transmitted from the terminal 20 to the server 10 as an example, and the server 10 generates a terminal display code. Then, the generated terminal display code is transmitted from the server 10 to the terminal 20, and the code display screen shown in FIG. 3-3 is displayed on the display unit 24 of the terminal 20.

FIG. 3-3 is a diagram showing an example of a code display screen.
On this code display screen, the characters "code" are displayed at the top of the screen, and below that, the payment method, the points owned by the user, and whether or not to use those points for payment are set. A point tab for doing this is displayed.

Below that, as the code image of the terminal display code acquired from the server 10, a one-dimensional terminal display code image represented by a barcode and a two-dimensional terminal display code represented by a QR code. The image QC0 and the image QC0 are displayed in different areas in the display screen. Further, as an example, not a limitation, a 12-digit payment number is displayed below the one-dimensional terminal display code image.

Further, in this example, the terminal display code displayed on the code display screen has a deadline for displaying the code (hereinafter, referred to as "code display deadline").

The code display deadline is not limited, but is, for example, a period during which the terminal display code is displayed on the terminal 20. The code display deadline is not limited, but can be, for example, "the period from the time (date and time) when the terminal display code is displayed (display started) on the terminal to the elapse of the code display time". The code display time can be changed as appropriate, but it is not limited and can be set to "5 minutes" as an example.

The code display deadline is not defined as the period during which the terminal display code is displayed on the terminal 20, but is defined as the time (date and time) when the period during which the terminal display code is displayed on the terminal 20 ends (expires). You may or may not do so.

Then, under the two-dimensional terminal display code image QC0, the remaining time of the code display deadline is displayed in a countdown format together with the update mark and the update character. The remaining time is displayed based on the information measured by the clock unit 29A of the terminal 20.
When the remaining time reaches "0", the code display screen is closed and the terminal display code is hidden. After that, if the user of the terminal 20 wants to make a payment, it is necessary to reacquire the terminal display code from the server 10.

The user of the terminal 20 presents the code display screen of FIG. 3-3 to the store clerk at the code cash register 60 within the code display deadline, and has the store code reader device 50 read the terminal display code image for payment. I do. In this case, the store code reader device 50 accesses the server 10 by the communication I / F 54 using the API or the like described above, and transmits the information necessary for payment to the server 10. As a result, the server 10 performs the payment process.

Up to this point, the processing for realizing online payment has been illustrated. In this process, the terminal display code generated by the server 10 and transmitted to the terminal 20 is not limited, but is immediately used for payment as an example.

However, some users may wish to use the terminal display code received from the server 10 to make a payment, instead of using it immediately to make a payment.

Further, in order to apply the above processing, it is necessary that the terminal 20 and the server 10 are in a communicable state (online state). Of course, it is also necessary that the store code reader device 50 and the server 10 are in a communicable state.

However, when making a payment in a place with poor radio wave conditions such as underground, or when making a payment in a situation where the line is congested such as an event venue, the communication volume of the terminal 20 for a certain period (for example, one month) is a certain amount. It is assumed that it will be difficult to make a payment as a result of communication failure (or communication difficulty) between the terminal 20 and the server 10 when communication restrictions or communication speed restrictions are applied due to exceeding the limit. Will be done.

Therefore, in the following, a method for realizing settlement even in these cases will be illustrated.
The settlement method described below can be similarly applied to both the online state and the offline state, but here, it will be described as a method for realizing the settlement in the offline state.

(2) Offline Payment An offline payment method as one aspect of the method of the present disclosure will be described with reference to a flowchart.
In the following, "offline" means that the terminal 20 cannot communicate with the server 10, and "offline state" means this offline state. Further, "offline payment" means that payment is performed by the server 10 in the offline state. Further, as a premise, it is assumed that the store code reader device 50 can communicate with the server 10.

FIG. 3-4 is a flowchart showing an example of the flow of processing executed by each device in this case. The way of reading the figure is the same as the above-mentioned flowchart.

The flowchart of FIG. 3-4 is a rewrite of the flowchart of FIG. 3-1 to an offline specification. The flowchart of FIG. 3-1 is not limited, but as an example, the processing step in the online state (for example, A240), the processing step in the offline state (for example, A250, B250, B280), and the case of returning from the offline state to the online state. (For example, A290, C290) are different.

After A130, the control unit 21 stocks the received terminal display code (terminal display code image in this example) in the storage unit 28 (A240).

Here, the “stock” means that the received terminal display code is stored in the storage unit 28 so that it can be used later.
In addition, in this specification, "stock" may be simply expressed as "memory". In addition, stocking the terminal display code may be expressed as "storing the terminal display code in the terminal display code stock data".

In this process, in order to enable offline payment, the terminal display code (terminal display code image in this example) acquired from the server 10 in the online state is stocked (stored) in the storage unit 28 of the terminal 20. .. Then, when payment is required in the offline state, the stock terminal display code is used so that payment can be performed without having to communicate with the server 10.

This will be described in detail. It is assumed that the user goes offline after A240.
Here, the terminal 20 detects that the terminal 20 has been taken offline by any of the following methods, as an example, not limited to the above.

(A) While the payment application is being executed on the terminal 20, a connection confirmation request is transmitted from the server 10 to the terminal 20 at a periodic timing or a specific timing, and the terminal 20 identifies the connection confirmation request. A connection response including information (for example, application ID) is transmitted to the server 10. In this case, the control unit 21 of the terminal 20 determines that the user is in the offline state when the connection confirmation request is no longer received from the server 10.

(B) While the payment application is being executed on the terminal 20, a connection notification including identification information (for example, an application ID) is transmitted from the terminal 20 to the server 10 at a periodic timing or a specific timing, and the server 10 sends the connection notification. In response to the connection notification, the connection confirmation is transmitted to the terminal 20. In the offline state, the connection notification cannot be transmitted from the terminal 20 to the server 10. Therefore, as an example, not limited to this, when the control unit 21 of the terminal 20 detects the occurrence of a connection notification transmission error, it determines that the terminal 20 is in the offline state.

It should be noted that, as an example, the terminal 20 acquires information on the communication status of its own terminal 20 by using a library or an application for acquiring the network connection status, and determines whether or not the terminal 20 is in the offline state. You may or may not do so.

In the offline state, as an example, not limited to, when the code display operation is performed by the user of the terminal 20, the control unit 21 performs the code display process (A250). Specifically, the terminal display code image stocked in A240 is displayed on the display unit 24. Then, when the displayed terminal display code image is presented to the store clerk or the like by the user of the terminal 20, the control unit 51 reads the terminal display code image displayed on the display unit 24 of the terminal 20 into a code reader. Control is performed so that the 58 can read (B250). Then, the control unit 51 shifts the processing to B160.

After B160, when the store payment completion notification is received from the server 10 by the communication I / F54 (B280), the store clerk or the like indicates that the offline payment has been completed (successful) based on the received store payment completion notification. Orally notify the user of the terminal 20.

After C180, the control unit 11 transmits a terminal payment completion notification to the terminal 20 (C290). However, in the offline state, the terminal 20 cannot receive the payment completion notification for the terminal. When the terminal 20 returns to the online state, the terminal 20 receives the payment completion notification for the terminal transmitted from the server 10. Then, when the terminal payment completion notification is received from the server 10 by the communication I / F 22, the control unit 21 causes the display unit 24 to display the payment result based on the received terminal payment completion notification (A290).

The process described above is an example of a process for performing offline payment.

The code generation request information may be information for requesting the generation of one terminal display code, or may be information for requesting the generation of a plurality of (two or more) terminal display codes. Specifically, as an example, not limited, the number of codes requested by the terminal 20 to be generated at one time on the terminal 20 side or the server 10 side, instead of adding the terminal display codes one by one. The upper limit of (the number of codes generated by the server 10 at one time) is set. Then, the user of the terminal 20 may acquire the upper limit number of terminal display codes at once by one operation. In this case, the server 10 generates a plurality of terminal display codes, the generated plurality of terminal display codes are transmitted to the terminal 20, and the received plurality of terminal display codes are stocked in the terminal 20. do it.

The above processing can be similarly applied in the online state. In other words
(1) When making a payment later using the terminal display code in the online state (2) When making an offline payment, as described above, it is generated and transmitted by the server 10 in the online state. The terminal display code is stocked in the terminal 20. Then, the payment is made using the terminal display code stocked in the terminal 20.

However, some users may forget that the terminal display code is stocked in the terminal 20.
Further, for example, when a plurality of terminal display codes are stocked in the terminal 20, the user determines the number of terminal display codes that have already been used for payment and the number of terminal display codes that have not yet been used for payment. It can be difficult to figure out.

<Functional configuration>
(1) Functional Configuration of Server FIG. 4-1 is a diagram showing an example of a function realized by the control unit 11 of the server 10 in this embodiment.

In the following, a case where the user of the terminal 20 uses the payment application stored in the terminal 20 to make a payment by the above-mentioned payment type “terminal code display” is illustrated as an example without limitation.

The server 10 has a payment management processing unit 111 as a function realized by the control unit 11.

The payment management processing unit 111 manages various information and data related to the payment application executed on the terminal 20 according to the payment management processing program 151 stored in the storage unit 15, and electronic money of the terminal 20 or the user of the terminal 20. It has a function to execute the payment management process for managing the payment by.

In this embodiment, the payment management processing unit 111 executes, for example, the processing shown in FIG. 3-4 as the payment management processing according to the payment management processing program 151 stored in the storage unit 15.

The payment management processing unit 111 is not limited to, but as an example, includes a terminal display code generation processing unit 1111 that generates a terminal display code by the terminal display code generation processing, and a payment processing unit 1113 that executes payment by the payment processing. Included as a functional part.

The terminal display code generation processing unit 1111 generates a terminal display code image represented by a two-dimensional code, not as a limitation but as an example. A two-dimensional code is a display-type code that has information in the horizontal and vertical directions, and is a matrix-type code in which small squares are arranged vertically and horizontally (hereinafter referred to as "matrix code") and a primary code. There is a stack-type code (hereinafter referred to as "stack code") in which a plurality of original codes (bar codes as an example, not limited) are stacked one above the other.

In this embodiment, for the sake of simplicity, a QR code (registered trademark), which is an example of a widely used matrix code, will be described as an example of a terminal display code.

In addition, unlike this embodiment, as a matrix code other than the QR code, a code such as an SP code, a veri code, a maxi code, a CP code, or a chameleon code may or may not be used. Further, various stack codes may or may not be used instead of the matrix code.

Further, the terminal display code generation processing unit 1111 generates a one-dimensional code (bar code as an example, not a limitation) in addition to a two-dimensional code (a QR code as an example, not a limitation) as a terminal display code. You may or may not do so. This is because some stores do not support reading of two-dimensional codes, but may support reading of one-dimensional codes.

The payment processing unit 1113 has a function of performing payment processing based on the information transmitted from the store POS system 40 and the information transmitted from the terminal 20 as an example, not limited to.

FIG. 4-2 is a diagram showing an example of information stored in the storage unit 15 of the server 10 in this embodiment.
The storage unit 15 stores, as an example, not a limitation, a payment management processing program 151 that is read by the control unit 11 and executed as a payment management processing as a program.

Further, the storage unit 15 stores user registration data 153, store registration data 155, payment management database 157, and code management database 159 as data, not by limitation.

The user registration data 153 is the registration data of the terminal 20 using the payment service and the user of the terminal 20, and an example of the data structure is shown in FIG. 4-3.
The user registration data 153 stores, as an example, not limited to, a user name, a terminal telephone number, a terminal email address, an application ID, an authentication password, and other registration information in association with each other.

<Display screen example>
FIG. 4-12 is a diagram showing an example of a top screen of a payment application displayed on the display unit 24 of the terminal 20 in this embodiment.
The configuration of the top screen is the same as that in FIG. 3-2, and here, a state in which the "code icon" is touch-operated by the user of the terminal 20 is shown.

FIG. 4-13 is a diagram showing an example of a code display screen displayed on the display unit 24 of the terminal 20 in this embodiment. This code display screen is not limited, but is a screen displayed by touching the "code icon" as shown in FIG. 4-12, and the terminal display code is stored in the terminal display code stock data 2831. This is an example of a code display screen displayed when no one is stored.

On this code display screen, as an example, not limited, as an example of zero code remaining information, the message "There is no code remaining, currently available code is not in stock" is displayed with the "OK" icon. Has been done. The "OK" icon is an icon for the user of the terminal 20 to operate when approving the code remaining zero information, and when the "OK" icon is touch-operated, the code remaining zero information is displayed. Is erased.

On the other hand, when the "code icon" is touch-operated on the top screen of the payment application shown in FIG. 4-12 and at least one terminal display code is stored in the terminal display code stock data 2831. As an example, not a limitation, a code display screen including a terminal display code image similar to that in FIG. 3-3 is displayed.

The payment request information including the above is transmitted to the server 10 to cause the server 10 to make a payment.

In the above display screen example, the user of the terminal 20 can display the code display screen by touching, for example, the code icon without being aware of whether the terminal 20 is in the online state or the offline state. Convenience can be improved.

The terminal display code stocked in the terminal 20 can be used not only for offline payment but also for online payment. That is, it is not essential for the terminal 20 to determine (detect) whether or not it is in the offline state, and payment is made using the terminal display code stocked in the terminal 20 regardless of the online state / offline state. It is possible to do so.

<Processing>
FIG. 4-14 shows an example of the flow of the first code display processing executed by the code display processing unit 2113 of the terminal 20 according to the first code display processing program which is an example of the code display processing program 2823 in this embodiment. It is a flowchart which shows. This first code display process is executed in step A250 of the process of FIG. 3-4 as an example without limitation.

Here, in the process of FIG. 3-4, it is shown that the process ends after A290, but in reality, the process is looped.

Specifically, as an example, not limited to, when a code acquisition operation by the user of the terminal 20 is detected after A290, the control unit 21 returns the process to A110. On the other hand, when the code display operation by the user of the terminal 20 is detected after A290, the control unit 21 returns the process to A250.

As described above, the terminal display code data stored in the terminal display code stock data 2831 is not limited, but as an example, payment processing is performed by the server 10 using the terminal display code (C170). , After receiving the terminal payment completion notification from the server 10 on A290 (after returning to the online state and receiving the terminal payment completion notification from the server 10 when offline payment is performed), the code stock data for terminal display Removed from 2831. Therefore, when the processing is returned to the A250 after the A290, the stock terminal display code may have been used up and the remaining number of codes may be zero.

In the first code display process, the code display processing unit 2113 counts the remaining number of codes (D110). Then, the code display processing unit 2113 determines whether or not the remaining number of counted codes is zero (D120).

When it is determined that the remaining number of codes is zero (D120: YES), the code display processing unit 2113 acquires the display setting of the zero remaining number of codes information stored in the code remaining number related information display setting data 2835 (D120: YES). D130).

After that, the code display processing unit 2113 causes the display unit 24 to display the code display screen including the code remaining zero number information based on the display setting (for example, the setting of the display mode) acquired in D130 (D140). ..

After that, the code display processing unit 2113 determines whether or not the first display end condition is satisfied (D180). The first display end condition may be, for example, the detection of the approval operation of the code remaining zero information by the user of the terminal 20, the detection of the non-display operation of the code display screen by the user of the terminal 20, and the like. And it doesn't have to be.

When it is determined that the first display end condition is not satisfied (D180: NO), the code display processing unit 2113 stands by as it is. On the other hand, when it is determined that the first display end condition is satisfied (D180: YES), the code display processing unit 2113 ends the first code display process.

On the other hand, when it is determined that the remaining number of codes is not zero (D120: NO), the code display processing unit 2113 may obtain a code image of the terminal display code stored in the terminal display code stock data 2831 (for example, acquisition). A code display screen including the oldest terminal display code code image) is displayed on the display unit 24 (D150).

After that, the code display processing unit 2113 determines whether or not the second display end condition is satisfied (D190). The second display end condition may or may not be, for example, the detection of a non-display operation of the code display screen by the user of the terminal 20, the lapse of the above-mentioned code display deadline, or the like. ..

When it is determined that the second display end condition is not satisfied (D190: NO), the code display processing unit 2113 stands by as it is. On the other hand, when it is determined that the second display end condition is satisfied (D190: YES), the code display processing unit 2113 ends the first code display process.

As described above, the method of the present disclosure can be applied as long as the terminal display code is stocked in the terminal 20. Therefore, the above-mentioned first code display process can be similarly applied regardless of the online state / offline state.

<Code>
In the above processing, the terminal 20 requests the server 10 to generate the terminal display code image, and the terminal display code image generated by the server 10 is transmitted to the terminal 20. Not limited to this. For example, the terminal 20 may request the server 10 to generate the original information (payment number in this example), and the original information generated by the server 10 may be transmitted to the terminal 20. You don't have to do that.

Specifically, in the process of FIG. 3-1 in A110, the control unit 21 transmits code generation request information for requesting the server 10 to generate the original information (payment number in this example). Then, based on this code generation request information, in C120, the control unit 11 generates the original information, and in C130, the generated original information is transmitted to the terminal 20. When the original information is received from the server 10 in the A130, the control unit 21 generates a terminal display code image based on the received original information (payment number in this example). Then, the control unit 21 causes the display unit 24 to display the generated terminal display code image.

Similarly, in the process of FIG. 3-4, when the original information (settlement number in this example) is received from the server 10 in A130, the control unit 21 in A240 receives the received original information (settlement number in this example). ) Is stored in the terminal display code stock data 2831. Then, the control unit 21 reads the stocked original information from the terminal display code stock data 2831, and generates a terminal display code image based on the read original information. Then, in A250, the control unit 21 causes the display unit 24 to display the generated terminal display code image.

Further, unlike the above, the terminal 20 requests the server 10 to generate the terminal display code image, and the terminal display code image generated by the server 10 is transmitted to the terminal 20, but on the terminal 20 side, Instead of stocking the terminal display code image received from the server 10, the original information acquired by decoding from the terminal display code image received from the server 10 may or may not be stocked. Good.

In addition, at the bottom of this code display screen, as an example of zero code remaining information, the message "There is no available code other than the displayed code." Is displayed. Therefore, the terminal can notify the user of the terminal that the first information other than the first information displayed in the display area is not stored in the storage unit.

<First modification (3)>
In the first embodiment, the "first information (code information)" in the present disclosure is a payment number and a terminal display code image including the payment number, but the present invention is not limited to this. For example, a token which is a kind of authentication information and a terminal display code image including the token can be used as "first information (code information)" in the present disclosure.

In this case, instead of including the payment number in the terminal display code image, the token issued by using the method (algorithm) to generate a random token is included in the terminal display code image as an example rather than limitation. It may or may not be. In this case, on the server 10 side, the identification information for identifying the terminal 20 or the user of the terminal 20 is associated with the issued token and stored in the code management data of the code management database 159 of the storage unit 15. You can do it like this.

The "token" is not limited, but as an example, is a kind of authentication information for the server 10 to authenticate that the terminal 20 or the user of the terminal 20 is a user of the legitimate terminal 20 or the legitimate terminal 20. is there. The "authentication information" is information issued by a certificate authority, and the above token functions as authentication information issued by the server 10 as a certificate authority to authenticate the terminal 20 or the user of the terminal 20.

The token can also be expressed as, for example, a "random token", an "access token", a "payment token", or the like. Since the tokens are randomly issued as described above, they become different tokens each time the terminal display code is generated. Therefore, the token functions as a one-time password, so to speak.

In addition to the payment number and token, the server 10 is an example of access information for the store code reader device 50 that has read the terminal display code image to access the website or web page provided by the server 10. Information such as a URL (Uniform Resource Locator) for accessing a payment page, which is a type of web page to be provided, may or may not be included.

The process of instructing (guidance) the user to make the user may or may not be performed. This process is an example of a process related to settlement.

Specifically, as an example, not limited to, in the code display screen for displaying the terminal display code image, in an area different from the area for displaying the terminal display code image, "the displayed code image is the store code. You can display a message such as "Please have the reader read it."

<First modification (5)>
In the first embodiment, when the code remaining number is zero, the code remaining number zero information is displayed, but the present invention is not limited to this. For example, when the number of remaining codes is less than or less than a certain number (for example, any number from "1" to "3"), the terminal 20 indicates that the remaining number of codes is insufficient. , Or information suggesting that the remaining number of codes is insufficient may or may not be displayed on the display unit 24.

<First modification (6)>
The display screen of the payment application described in the first embodiment is merely an example, and the design can be changed as appropriate. For example, on the top screen of the payment application, a "code (offline) icon" indicated as "code (offline)" is displayed in addition to the above-mentioned "code icon". Then, when it is determined that the terminal 20 is in the online state, the terminal display code is displayed when the "code icon" is operated, and when it is determined that the terminal 20 is in the offline state, the "code" is displayed. The terminal display code may or may not be displayed when the "(offline) icon" is operated.

<First modification (7)>
In A130 of the process of FIG. 3-4, at the timing when the terminal 20 receives the terminal display code from the server 10, the processes of A240 and A250 are performed so that the terminal display code is displayed on the display unit 24. You may or may not have to do so.

In this case, as an example, the display can be switched to the code display screen of the terminal display code as it is after the code icon is touch-operated on the top screen of the payment application (for example, FIG. 3-2). ..

<Second Example>
In the second embodiment, as another example of the code remaining number-related information, the information indicating the code remaining number or the information suggesting the code remaining number (hereinafter, collectively referred to as "code remaining number information") is referred to as the terminal 20. This is an embodiment in which the display unit 24 of the above is displayed.

The contents described in the second embodiment can be applied to any of the other embodiments and the other modifications.

That is, it is also possible to display the code remaining number marks having different facial expressions and different face colors according to the code remaining number.

<Processing>
FIG. 5-7 shows an example of the flow of the second code display processing executed by the code display processing unit 2113 of the terminal 20 according to the second code display processing program which is an example of the code display processing program 2823 in this embodiment. It is a flowchart which shows. This second code display process is executed in step A250 of the process of FIG. 3-4 as an example but not a limitation.
The same steps as those in the first code display process (FIG. 4-14) are designated by the same reference numerals, and the description thereof will be omitted again.

The process of FIG. 5-7 is a rewrite of the process after D110 of the first code display process (FIG. 4-14).

After D110, the code display processing unit 2113 acquires the display setting of the code remaining number information stored in the code remaining number related information display setting data 2835 (E130). After that, the code display processing unit 2113 displays a code display screen including the code remaining number information and the terminal display code image based on the display setting (for example, the setting of the display mode) acquired by E130. Is displayed (E140).

After that, the code display processing unit 2113 determines whether or not the third display end condition is satisfied (E190). The third display end condition may or may not be, for example, the detection of a non-display operation of the code display screen by the user of the terminal 20, the lapse of the above-mentioned code display deadline, or the like. ..

When it is determined that the third display end condition is not satisfied (E190: NO), the code display processing unit 2113 stands by as it is. On the other hand, when it is determined that the third display end condition is satisfied (E190: YES), the code display processing unit 2113 ends the second code display process.

<Effect of the second embodiment>
In the second embodiment, the code image of the terminal display code and the original information (not limited, but an example of the first information) are stored in the terminal display code stock data 2831, that is, the remaining number of codes (stock number). Indicates a configuration in which the code remaining number information (not limited, but an example of information on the number of times the first information is stored in the storage unit) is displayed on the code display screen.
As an example of the effect obtained by such a configuration, the terminal displays the information regarding the number of the first information stored in the storage unit in the display area, so that the number of the first information stored in the storage unit is displayed. Can be notified to the user.

Further, in this case, the code remaining number zero information shown in the first embodiment is the number of code images and original information of the terminal display code stored in the terminal display code stock data 2831 among the code remaining number information. It shows a configuration that is information indicating that it is zero.
As an example of the effect obtained by such a configuration, the terminal notifies the user that the number of the first information stored in the storage unit is zero as well as the number of the first information stored in the storage unit. be able to.

Further, in the second embodiment, the code remaining number information is displayed in a different display mode based on the number of code images and original information of the terminal display code stored in the terminal display code stock data 2831. Is shown.
As an example of the effect obtained by such a configuration, the terminal can display the number of first information stored in the storage unit so that the user can easily grasp (at first glance).

Further, the second embodiment shows a configuration in which the terminal 20 executes control for changing the display mode of the remaining code information by the control unit 21 based on displaying the terminal display code image on the code display screen. There is.
As an example of the effect obtained by such a configuration, the terminal displays the first code image by controlling the display mode of the information regarding the number based on displaying the first code image in the display area. Therefore, the number of first information stored in the storage unit can be appropriately notified to the user.

<Second modification (1)>
In the second embodiment, when the remaining number of codes is relatively large, the remaining number of codes information may not be completely displayed on the screen or the appearance may be deteriorated depending on the display method of the remaining number of codes information. Therefore, the upper limit of the remaining code information to be displayed may or may not be set.

Further, in this case, when the remaining number of codes exceeds the upper limit, the code remaining number information may be displayed in the same manner as when the remaining number of codes is the same as the upper limit. It does not have to be. For example, if the upper limit is set to "5", when the remaining number of codes exceeds 5, the remaining number of codes information is displayed in the same manner as when the remaining number of codes is 5. Can be.

For example, the code display screen of FIG. 5-4 described above is a case where the number of remaining codes is "5", and the five areas (all areas) of the remaining number of codes gauge are displayed in color. , The character "FULL" is displayed on the right side of the code remaining number gauge. In this case, even when the number of remaining codes exceeds 5, the remaining number of codes information may or may not be displayed in the same manner as the code display screen of FIG. 5-4.

Also, unlike this, when the number of remaining codes is 5, the 5 areas (all areas) of the remaining code gauge are displayed in color, but the characters "FULL" are not displayed. When the number of remaining codes exceeds 5, the characters "FULL" may or may not be displayed.

Further, here, the case where the code remaining number information is displayed in the gauge format of FIGS. 5-3 and 5-4 is illustrated, but the same applies to the case where the code remaining number information is displayed by another method.

Specifically, for example, if the remaining number of codes is expressed by a number, the number when the remaining number of codes exceeds the upper limit is expressed by the same number as when the remaining number of codes is the same as the upper limit. It should be.
Also, for example, if the remaining number of codes is expressed by the color density, the color density when the remaining number of codes exceeds the upper limit is the same as the same color as when the remaining number of codes is the same as the upper limit. It may be expressed by the density of.

<Second modification (2)>
As described in the first modification (2), the terminal display code displayed on the code display screen can be excluded from the count of the remaining number of codes.

In this case, as described above, when one terminal display code is read from the terminal display code stored in the terminal display code stock data 2831 and displayed, the terminal display code data is stored. It is moved to the active storage area of unit 28 and deleted from the terminal display code stock data 2831.

After that, the total number of terminal display codes stored in the terminal display code stock data 2831 is counted as the remaining number of codes. By doing so, the terminal display code displayed on the code display screen is excluded from the count of the remaining number of codes. Then, based on the code remaining number counted in this way, the code remaining number information can be displayed in the manner shown in FIGS. 5-1 to 5-6, for example.

<Second modification (3)>
The process that combines the display of the zero code remaining number information described in the first embodiment and the display of the code remaining number information described in the second embodiment may or may not be executed. Good.

FIG. 5-8 shows an example of the flow of the third code display processing executed by the code display processing unit 2113 of the terminal 20 according to the third code display processing program which is an example of the code display processing program 2823 in this modification. It is a flowchart which shows. This third code display process is executed in step A250 of the process of FIG. 3-4 as an example but not a limitation.
The same steps as those in the above-described processing are designated by the same reference numerals, and the description thereof will be omitted again.

The process of FIG. 5-8 is a combination of the first code display process (FIG. 4-14) and the second code display process (FIG. 5-7).

After D110, when it is determined that the remaining number of counted codes is zero (D120: YES), the code display processing unit 2113 ends the third code display process after performing the processes of D130 to D180.

On the other hand, when it is determined that the remaining number of counted codes is not zero (D120: NO), the code display processing unit 2113 ends the third code display process after performing the processes of E130 to E190.

<Second modification (4)>
A terminal display code generated by the server 10 is set with an expiration date (hereinafter referred to as "code expiration date") at which payment can be made using the terminal display code, and this code expiration date is set. Information can be displayed in a manner recognizable by the user of the terminal 20.

The code expiration date can be an expiration date managed on the server 10 side for each generated terminal display code. For example, the date and time when the server 10 generates the terminal display code is defined as the "code generation date and time", and the valid time of the code set by the server 10 is defined as the "code valid time". In this case, as an example, not limited, "the period from the code generation date and time until the code valid time elapses" is set as the code expiration date.

FIG. 5-9 is a flowchart showing an example of the flow of processing executed by each device in this modified example. From the left side, an example of a process executed by the control unit 21 of the terminal 20, a process executed by the control unit 51 of the store code reader device 50, and a process executed by the control unit 11 of the server 10 is shown.

The flowchart of FIG. 5-9 is a partial rewrite of the flowchart of FIG. 3-4. The flowchart of FIG. 3-4 is different from the flowchart of FIG. 3-4 in steps such as A330 to A350, B350, B360, C320, C330, and C370 as an example without limitation.

In this process, as an example, the terminal 20 or the identification information for identifying the user of the terminal 20 will be described as the application ID described above.

After C110, the control unit 11 of the server 10 performs a terminal display code generation process (C320). Specifically, as an example, not limited, a random number with a predetermined number of digits is used by using a method (algorithm) for generating a random number with a predetermined number of digits (for example, about 10 to 12 digits). Is generated as a payment number. Then, as an example, not a limitation, a terminal display code image including at least a payment number as original information is generated. More specifically, at least the payment number is encoded (encoded) and graphicized (imaged) to generate a terminal display code image represented by a two-dimensional code (for example, QR code) image.

Further, the control unit 11 is not limited to the code management data of the application ID included in the received code generation request information in the code management database 159, but as an example, the code generation date and time based on the timekeeping information of the clock unit 19 is used. , The code No., the generated payment number, and the code expiration date set for the generated terminal display code are stored in association with each other.

Next, the control unit 11 communicates the generated terminal display code (terminal display code image in this example) and the code expiration date set for the terminal display code together with the code No. as an example, not limited to the control unit 11. It is transmitted to the terminal 20 by the I / F 14 (C330).

When the terminal display code (terminal display code image in this example) and the code expiration date are received from the server 10 by the communication I / F 22 (A330), the control unit 21 of the terminal 20 receives the received terminal display code. (In this example, the terminal display code image) is stocked (A340). Specifically, the code data of the received terminal display code and the received code expiration date are associated with the code reception date and time and the code No., and stored in the terminal display code stock data 2831.

In the offline state, as an example, not limited to, when the code display operation is performed by the user of the terminal 20, the code display processing unit 2113 performs the code display processing (A350).

Specifically, the code display processing unit 2113 reads out the code data of the terminal display code stored in the terminal display code stock data 2831 as an example, and is not limited to the code display processing unit 2113, and displays the code including the terminal display code image. The screen is displayed on the display unit 24. At this time, the code display processing unit 2113 displays the code remaining number information and the code expiration date information in association with each other on the code display screen, not by limitation but as an example.

After that, when the terminal display code image displayed on the display unit 24 is presented to the store clerk or the like by the user of the terminal 20, the control unit 51 displays the terminal display code image displayed on the display unit 24 of the terminal 20. Is controlled to be read by the code reader 58 (B350).

After that, the control unit 51 accesses the server 10 by the communication I / F 54 using the above-mentioned application interface (API) or the like, and at least the payment number obtained by decoding from the read terminal display code image and the store identification. The payment request information including the information, the scheduled payment amount, and the time when the terminal display code image is read (hereinafter referred to as "code reading time") is transmitted to the server 10 by the communication I / F 54 (B360). ..

When the payment request information is received from the store code reader device 50 by the communication I / F 14 (C160), the control unit 11 performs the payment processing (C370).

Specifically, it is determined whether or not the payment number included in the received payment request information is stored in the code management database 159 in association with the application ID. Then, when it is determined that it is stored, the code reading time included in the received payment request information is within the code expiration date stored in association with the payment number in the code management data of the application ID. Determine if it exists. Then, when this condition is satisfied, it is determined that "settlement is possible", and the scheduled settlement amount is subtracted from the balance stored in the settlement management data of the application ID in the settlement management database 157A to settle the settlement.

FIG. 5-10 is a diagram showing an example of a code display screen in this modified example. This code display screen is not limited, but is displayed as an example in the process A350 of FIG. 5-9.
In this code display screen, as in the code display screen of FIG. 5-1, the code represented by, for example, a rectangle for the remaining number of counted codes is placed on the area where the one-dimensional terminal display code is displayed. The remaining number of images are displayed. However, unlike the code display screen shown in FIG. 5-1, the remaining number of codes corresponding to each terminal display code The color density of the image is dark based on the code expiration date associated with the corresponding terminal display code. It is displayed by.

In this case, the code display processing unit 2113 displays, as an example, not limited to, the color of the remaining code image corresponding to the terminal display code having a shorter remaining time of the code expiration date is made lighter in color. On the contrary, the remaining number of codes corresponding to the terminal display code having a longer remaining time of the code expiration date is displayed in a darker color.

In addition, instead of changing the color density of the code remaining number image based on the code expiration date, the color of the code remaining number image may be changed based on the code expiration date, or it may not be changed. Good. For example, the color of the remaining code image can be changed in the order of "red → orange → yellow → green → blue" in ascending order of the remaining time of the code expiration date.

By doing so, the terminal has the number of first information (code information) stored in the storage unit and the expiration date information (for example, expiration date) associated with each first information (code information). The remaining time) can be notified to the user of the terminal.

This method is effective, for example, when the terminal display code is acquired from the server 10 at a staggered time, or when the terminal display code is replenished from the server 10 at a staggered time. This is useful because the user of the terminal can grasp the deadline information at a glance.

In the above process, the server 10 transmits the terminal display code and the code expiration date (not limited, but an example of information on the expiration date) to the terminal 20, and the terminal 20 receives the code. However, it is not limited to this.

Specifically, the code valid time is stored in advance in the payment application data 283 of the terminal 20 as an example, not limited. Then, as an example rather than a limitation, the code generation date and time (an example of information regarding the expiration date, not the limitation) may be transmitted from the server 10, and the terminal 20 may receive the code generation date and time from the server 10. You may or may not have to do so. In this case, the terminal 20 can specify the code expiration date based on the received code generation date and time and the code validity time stored in the payment application data 283.

Further, the date and time when the code expiration date starts is not set as the code generation date and time, but may be set as the date and time when the terminal display code is transmitted from the server 10 to the terminal 20 (hereinafter, referred to as "code transmission date and time"). it can. In this case, the terminal 20 can specify the code expiration date based on the code transmission date and time and the code validity time stored in the payment application data 283, not by limitation but as an example.

In addition to this, as an example, not limited to this, information on the date and time when the code expiration date ends is transmitted from the server 10 to the terminal 20 as information on the expiration date. Then, the terminal 20 can specify the code expiration date based on the code expiration time and the date and time when the received code expiration date ends.

Further, the code expiration date associated with the terminal display code may not be transmitted from the server 10 to the terminal 20, and the terminal 20 may not know the code expiration date set by the server 10. In this case, the terminal display code stock data 2831 does not store the code expiration date, and is not limited, but as an example, the code reception date and time, the code No., and the code data can be stored in association with each other. ..

Further, in this case, the terminal 20 may or may not set a temporary code expiration date (hereinafter, referred to as "temporary code expiration date"). Specifically, as an example, instead of limiting, "the period from the date and time when the code was received (or the date and time when the code was stored) until the time when the code was valid" may be set as the temporary code expiration date, or so. It does not have to be.

<Third Example>
In the second embodiment, the code remaining number information is displayed on the code display screen, but as described above, there are two methods for counting the code remaining number. For this reason, it is difficult for the user to understand whether the terminal display code displayed on the code display screen is included in the code remaining number recognized from the code remaining number information or not included. There is.

The contents described in the third embodiment can be applied to any of the other embodiments and the other modifications.
Further, the same components as those already described will be designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 6-1 is a diagram showing an example of a code display screen in this embodiment.
In this code display screen, a first guide image represented by a rectangle with a number inside, for example, for the remaining number of counted codes, is displayed on the area where the one-dimensional terminal display code image is displayed. Is displayed.

In this display example, five first guide images are displayed, and as an example, the color of the first guide image displayed on the far left changes to black and rises to the front side. It is highlighted as a state. The remaining four first guide images are displayed in the default state. When any of the remaining four first guide images is touch-operated, the terminal display code image corresponding to the first guide image is displayed in the center of the screen.

FIG. 6-2 is a diagram showing another example of the code display screen in this embodiment.
On this code display screen, a second guide image that is a schematic (simulation) of, for example, a two-dimensional code for the remaining number of counted codes is displayed on the area where the one-dimensional terminal display code image is displayed. Has been done.

In this display example, five second guide images are displayed, and when any of the second guide images is touch-operated by the user, the touch-operated second guide is not limited, but as an example. Based on the terminal display code data corresponding to the image, the terminal display code image is displayed in the center of the screen by animation.

In this display example, since the leftmost second guide image is touch-operated, the entire image including the terminal display code image is displayed with reference to the display position of the leftmost second guide image. The enlargement processing is gradually performed so as to become a specified size based on the size of the display screen of the display unit 24, and finally, when the specified size is reached, the enlargement processing is completed and the image is on the right side of the drawing of FIG. 6-2. It is displayed in the indicated state. When the enlargement process is completed, the display of the corresponding second guide image is erased, and the remaining four second guide images are displayed packed to the left.

As in this example, after erasing the display of the guide image corresponding to the displayed terminal display code image, the remaining guide image is not packed and displayed, but the displayed terminal display code image. The display of the guide image corresponding to is erased, but the remaining guide images may or may not be displayed at the same position as they are without being packed.

FIG. 6-3 is a diagram showing another example of the code display screen in this embodiment.
In this code display screen, as in the code display screen of FIG. 6-2, the remaining number of counted codes, for example, a rectangle is represented on the area where the one-dimensional terminal display code image is displayed. The third guide image is displayed, but in this example, the touch-operated third guide image is displayed as it is (active state), and the remaining third guide image changes to the inactive state. The point that is displayed is different.

Specifically, in this display example, five third guide images are displayed, and when any third guide image is touch-operated by the user, the touch is performed as in FIG. 6-2. Based on the terminal display code data corresponding to the operated third guide image, the terminal display code image is displayed in the center of the screen by animation.

In this display example, since the leftmost third guide image is touch-operated, the entire image including the terminal display code image is displayed with reference to the display position of the leftmost third guide image. The enlargement processing is gradually performed so as to become a specified size based on the size of the display screen of the display unit 24, and finally, when the specified size is reached, the enlargement processing is completed and the image is on the right side of the drawing of FIG. 6-3. It is displayed in the indicated state. Further, the leftmost third guide image that has been touch-operated is displayed as it is (active state), and the remaining four third guide images are changed to the inactive state and displayed.

The second guide image and the third guide image described above are icons (marks) simulating a two-dimensional code image (for example, a QR code image), and are not real code images. Therefore, as a matter of course, these guide images cannot be read by a code reader and cannot be used for payment.

FIG. 6-4 is a diagram showing another example of the code display screen in this embodiment.
In this code display screen, a plurality of terminal display codes (terminal display code images) stored in the terminal display code stock data 2831 are not limited, but as an example, the user of the terminal 20 swipes. , It is configured so that it can be switched and displayed in a sliding manner.

Specifically, as an example, not limited, the same number as the terminal display code stored in the terminal display code stock data 2831 (that is, the code remains) on the area where the one-dimensional terminal display code image is displayed. A fourth guide image of a number (the same number as the number of stocks), for example, represented by a circle (◯), is displayed side by side in the horizontal direction.

The fourth guide image is not limited, but as an example, corresponding to the first terminal display code, the second terminal display code, the third terminal display code, and so on, in order from the left. Therefore, when the code image of the corresponding terminal display code is displayed in the center of the screen, the fourth guide image represented in white is changed to black and displayed.

In this display example, since the number of remaining codes (stock number) is 5, the 5 terminal display codes can be switched and displayed in a slide manner, and are represented by 5 circles corresponding to each. The fourth guide image to be displayed is displayed.

The left side of the drawing shows a state in which the first code image including the two-dimensional terminal display code image QC1 is displayed, the fourth guide image first from the left is displayed as a black circle, and the other fourth guide images are displayed. The guide image of 4 is indicated by a white circle.
The center of the drawing shows a state in which the user of the terminal 20 touches the display screen and then swipes to the left from that position. By swiping to the left, the display of the first code image including the two-dimensional terminal display code image QC1 is displayed, and the display of the second terminal display code including the two-dimensional terminal display code image QC2. Switch to.
The right side of the drawing shows the state in which the second terminal display code including the two-dimensional terminal display code image QC2 is displayed by this swipe operation, and the fourth guide image second from the left is a black circle. The other fourth guide images are displayed as white circles.

The various guide images illustrated above are code remaining number information (not limited, but an example of information on the number of first information stored in the storage unit), as well as the displayed terminal display code image and the original. This is an example of guidance information (guide information) for guiding (notifying) the user of the terminal 20 the correspondence relationship with the information (not limited, but an example of the first information).

The display order of the guide image and the terminal display code image in the above display example is not limited, but as an example, among the terminal display codes stored in the terminal display code stock data 2831, in order from the left. The acquisition can be in chronological order.

However, the display order is not limited to this. For example, among the terminal display codes stored in the terminal display code stock data 2831, the acquisition is displayed in the order of newest from the left. You may or may not have to do so.
It may or may not be displayed in a completely random order.

<Effect of the third embodiment>
In the third embodiment, a guide image (not a limitation, but an example of information on the number) based on the remaining number of codes is displayed on the code display screen displayed on the display unit 24 of the terminal 20, and the display position of the guide image is displayed. As a reference, the entire image including the terminal display code image is gradually enlarged so as to fill the display screen of the display unit 24 (not limited, but at the position where information about the number is displayed in the display area). An example of displaying the first code image in the nearby first area), and finally, when the size of the display screen of the display unit 24 reaches the full size, the enlargement ends and the terminal display code image is displayed (). An example of displaying the first code image in the second area farther than the first area from the position where the information about the number is displayed in the display area after the first code image is displayed in the first area without limitation. ) Shows the configuration.
As an example of the effect obtained by such a configuration, the terminal allows the terminal user to easily grasp the correspondence relationship between the information regarding the number of first information stored in the storage unit and the displayed first information. Can be displayed in (recognizable).

<Third modification (1)>
In the third embodiment, the display method when the terminal display code displayed on the code display screen is included in the count of the remaining number of codes is illustrated, but the terminal display code displayed on the code display screen is the code remaining. The same applies when excluding from the number count.

As described in the second modification (2), a method of excluding the terminal display code displayed on the code display screen from the count of the remaining number of codes and displaying the remaining number of codes information is also conceivable.
In this case, it is necessary to notify the user that the terminal display code (code image) displayed on the code display screen is not included in the remaining number of codes. Therefore, the following display can be performed as an example rather than a limitation.

For example, if a method of displaying a rectangular guide image is applied as shown in FIG. 6-1, the control unit 21 codes a code image of a stocked terminal display code as an example, not a limitation. It is displayed in the center of the display screen, and the guide images for the remaining number of counted codes are displayed by excluding the displayed one terminal display code. At this time, the control unit 21 displays all the guide images in the default state (no highlighting of any of the guide images).

Further, if a method of displaying a guide image simulating a two-dimensional code is applied as shown in FIGS. 6-2 and 6-3, the control unit 21 is not limited, but as an example, one terminal display. The code image of the code is displayed in the center of the code display screen, and the guide images for the remaining number of codes counted by excluding the displayed one terminal display code are displayed. At this time, the control unit 21 displays all the guide images in the inactive state (none of the guide images are displayed in the active state).

More specifically, for example, when the remaining number of codes counted by excluding the terminal display code displayed on the code display screen is "5", the guide of "5" in the above display mode. Display the image on the code display screen.

By doing so, the user can recognize that the displayed terminal display code image does not correspond to the guide image (it does not correspond), and as a result, the displayed code (code image). ) Can be understood by the user as not being included in the remaining code.

<Third modification (2)>
As described above, the terminal display code in the present disclosure can be used not only in the online state but also in the offline state. In the online state, the terminal 20 can receive the terminal payment completion notification from the server 10 immediately after the payment is made by the server 10. Therefore, the terminal 20 is not limited, but as an example, after receiving the terminal payment completion notification, the terminal display code data used for the payment can be deleted from the terminal display code stock data 2831.

However, in the offline state, the terminal 20 cannot receive the payment completion notification for the terminal from the server 10 until the terminal 20 returns to the online state, so that it is not possible to know whether or not the payment has been made by the server 10. Therefore, in the offline state, for example, even if the user of the terminal 20 uses one terminal display code displayed on the code display screen for payment (even if the store code reader device 50 reads it), the terminal 20 Cannot delete the terminal display code. Therefore, for example, the user of the terminal 20 may redisplay the terminal display code once used for payment on the code display screen and try to use it for payment again.

Therefore, for example, on the code display screen shown in FIG. 6-4, when the control unit 21 of the terminal 20 detects the swipe operation of the user and switches the display to the next terminal display code image, the display is displayed before the switching. The data of the terminal display code that has been used may be deleted (destroyed) so that it cannot be displayed again, or it is not necessary to do so.

This also applies to other display methods (for example, the display methods of FIGS. 6-1 to 6-3). That is, the terminal display code that has been once displayed and hidden can be deleted so that it cannot be displayed again (that is, it cannot be used for payment).

In addition, as another method, the following can be performed.
When the terminal 20 detects that it is in the online state, the terminal display code that has been once displayed and hidden can be redisplayed without being deleted.
On the other hand, when the terminal 20 detects that it is in the offline state, the terminal display code that has been once displayed and hidden cannot be deleted and redisplayed.

<Third modification (3)>
In addition to the various methods for displaying the remaining number of codes described above, the user of the terminal 20 swipes (for example, for example) a page on which one terminal display code is displayed, such as a so-called daily calendar, without limitation. It is also possible to apply a display method in which a page displaying the next terminal display code appears when the flip operation is performed by swiping from bottom to top).

Also, in this case, as in the third modification (2), once the page is turned, the terminal display code data displayed on the previous page cannot be displayed again by deleting it. It may or may not be.

<Third modification (4)>
In the third embodiment, an example in which a terminal display code image is displayed by using a touch operation on the guide image as a trigger is shown, but the present invention is not limited to this. Specifically, the various guide images described above are used as information (code remaining number information) indicating the remaining number of codes (stock number), and the code image for terminal display is triggered by an operation different from the touch operation on the guide image. May or may not be displayed.

The terminal 20 displays a code display screen including code images for the remaining number of codes based on the touch operation of the code icon displayed on the top screen of the payment application as an example, not limited to the terminal 20. At this time, as an example, not limited to, operation images such as a button for displaying / switching code information (including code image and original information) and a button for displaying / switching page are also displayed on the code display screen. Let me.

Then, each time the terminal 20 detects an operation (for example, a touch operation) on the above-mentioned operation image, the terminal 20 is not limited, but as an example, the random order or acquisition is old from the terminal display code corresponding to the guide image. The terminal display code images are displayed in order, and the display mode of the guide image is changed.

<Fourth Example>
The fourth embodiment is an embodiment relating to the replenishment of the stock of the terminal display code stocked by the terminal 20 and the user interface thereof.

The contents described in the fourth embodiment can be applied to any of the other embodiments and the other modifications.
Further, the same components as those already described will be designated by the same reference numerals, and the description thereof will be omitted again.

<Processing>
FIG. 7-1 is a flowchart showing an example of the flow of processing executed by each device in this embodiment. The left side shows the first terminal side code replenishment process executed by the control unit 21 of the terminal 20, and the right side shows the first server side code replenishment process executed by the control unit 11 of the server 10.

These processes are not limited, but as an example, are processes executed as sub-processes of the payment application process of the terminal 20 described above and the payment management process of the server 10 described above (for example, executed in the background). is there.

First, the control unit 21 performs a code replenishment condition determination process (F110). As the code replenishment condition, for example, the following conditions can be defined.
(1) Displaying zero code remaining information & detecting an approval operation.
(2) The code replenishment operation has been detected.
(3) The electromagnetic wave environment (communication environment) of the terminal has changed.
(4) The code update timing and update time have come.

The condition (1) is that the code is replenished when the control unit 21 displays the code remaining zero information on the display unit 24 and then detects an approval operation by the user of the terminal 20 for the code remaining zero information. It is a condition to show that.
It should be noted that the detection of the approval operation may not be included in the condition. Specifically, when the control unit 21 displays the zero code remaining number information on the display unit 24, the code may or may not be automatically replenished.

The condition (2) is a condition indicating that the code is replenished when the operation for replenishing the code by the user of the terminal 20 (hereinafter referred to as "code replenishment operation") is detected.

The condition (3) is a condition indicating that the code is replenished when the electromagnetic wave environment (communication environment) of the terminal 20 changes. Since radio waves are generally used for communication, the change in the radio wave environment may be used instead of the change in the electromagnetic wave environment.

As an example, not a limitation, if it is detected that the electromagnetic wave environment of the terminal 20 has changed from the "medium electromagnetic wave environment" to the "weak electromagnetic wave environment" based on the strength of the electromagnetic wave, it may go offline. The terminal display code can be replenished.

The condition (4) is a condition indicating that the code is replenished at a regular timing (for example, once every 12 hours or 24 hours) or at a specific time (for example, midnight). ..

In F110, the control unit 21 determines, for example, whether or not at least one of the above-mentioned plurality of code replenishment conditions is satisfied, not as a limitation.

It should be noted that the above code replenishment condition is merely an example, and conditions other than these can be defined.
Further, as an example, not a limitation, a condition in which two or more of the above code replenishment conditions are combined may be defined as a code replenishment condition.
Further, as an example, not limited to the above, it is possible to set which of the above code replenishment conditions is to be applied by letting the user of the terminal 20 select.

If it is determined that the code replenishment condition is satisfied (F120: YES), the control unit 21 determines whether or not it is in the online state (F130). Then, if it is determined that the user is online (F130: YES), the control unit 21 transmits, for example, code replenishment request information including at least the application ID to the server 10 by the communication I / F22 (F130: YES). F140).

Instead of the code replenishment request information, the code generation request information described above may or may not be transmitted from the terminal 20 to the server 10.

The control unit 11 of the server 10 determines whether or not the code replenishment request information has been received from the terminal 20 (G110). Then, if it is determined that the signal has been received (G110: YES), the terminal display code generation process is performed (G120). Then, the control unit 21 transmits the generated terminal display code to the terminal 20 by the communication I / F 14 (G150).

After that, the control unit 11 determines whether or not to end the process (G190), and if it determines that the process is to be continued (G190: NO), returns the process to G110. If it is determined that the process is terminated (G190: YES), the first server-side code replenishment process is terminated.

If the code generation request information is not received from the terminal 20 (G110: NO), the control unit 11 shifts the process to the G190.

When the terminal display code is received from the server 10 by the communication I / F 22 (F150), the control unit 21 adds and stores the received terminal display code in the terminal display code stock data 2831 (F160).

After that, the control unit 21 performs code replenishment notification processing (F170). In this code replenishment notification process, information for notifying that the stock of the terminal display code has been replenished (hereinafter, referred to as "code replenishment notification information") is displayed on the display unit 24.

Specifically, as an example, not limited to, when the payment application is not being executed, the code replenishment notification information is displayed on the display unit 24 by the push notification associated with the payment application.
On the other hand, when the payment application is being executed, the code replenishment notification information is displayed on the screen (for example, the code display screen) in the payment application.

After that, the control unit 21 determines whether or not to end the process (F190), and if it determines that the process is to be continued (F190: NO), returns the process to F110. If it is determined that the process is to be completed (F190: YES), the first terminal-side code replenishment process is terminated.

If it is determined that the code replenishment condition is not satisfied (F120: NO), or if it is determined that the code replenishment condition is not satisfied (F130: NO), the control unit 11 shifts the process to F190.

The code replenishment request information may be information for requesting replenishment of one terminal display code, or may be information for requesting replenishment of a plurality of (two or more) terminal display codes. Specifically, as an example, not limited, the number of codes requested by the terminal 20 to be replenished at one time on the terminal 20 side or the server 10 side, instead of replenishing the terminal display codes one by one. The upper limit of (the number of codes generated by the server 10 for replenishment at one time) is set. Then, the user of the terminal 20 may replenish the terminal display code of the upper limit number at once by one operation. In this case, the server 10 generates a plurality of terminal display codes, the generated plurality of terminal display codes are transmitted to the terminal 20, and the received plurality of terminal display codes are replenished by the terminal 20. do it.

<Display screen example>
FIG. 7-2 is a diagram showing an example of a code display screen in this embodiment.
Similar to the code display screen shown in FIG. 6-3, the code display screen is a schematic two-dimensional code as an example of the remaining code information on the area where the one-dimensional terminal display code image is displayed.

It shows a configuration in which a request for transmission of the first information) is transmitted to the server 10 via the communication I / F 22.
As an example of the effect obtained by such a configuration, the terminal can transmit a request for transmission of the first information to the server based on the display of the second information, and can acquire the first information from the server.

<Fifth Example>
The fifth embodiment is an embodiment in which the stock of the terminal display code is replenished from the offline state.

The contents described in the fifth embodiment can be applied to any of the other embodiments and the other modifications.
Further, the same components as those already described will be designated by the same reference numerals, and the description thereof will be omitted again.

In this embodiment, the fact that the terminal 20 and the server 10 cannot communicate with each other by the first communication method described above is defined as an "offline state". Further, by using the second communication method described above, the terminal 20 can communicate with the server 10.

<Processing>
8-1 and 8-2 are flowcharts showing an example of the flow of processing executed by each device in this embodiment. The second terminal-side code replenishment process executed by the control unit 21 of the terminal 20 is shown on the left side, and the first server-side code replenishment process executed by the control unit 11 of the server 10 is shown on the right side.
These processes are not limited, but as an example, are processes executed as sub-processes of the payment application process of the terminal 20 described above and the payment management process of the server 10 described above (for example, executed in the background). is there.

The flowcharts of FIGS. 8-1 and 8-2 are obtained by adding the processing (F210 to F280) in the case of F130: NO to the flowchart of FIG. 7-1.

If it is determined in F130 that the state is not online (F130: NO), the control unit 21 determines whether or not the number of remaining codes is zero (F210).

If it is determined that the number of remaining codes is zero (F210: YES), the control unit 21 performs a notification of zero remaining codes and an offline notification (F220). Specifically, as an example, not limited, the display unit 24 displays information indicating that communication with the server 10 by the first communication method is impossible (offline state) together with the code remaining number zero information.

On the other hand, if it is determined that the remaining number of codes is not zero (F210: NO), the control unit 21 performs an offline notification (F230). Specifically, the display unit 24 displays information indicating that communication with the server 10 by the first communication method is impossible (offline state), not as a limitation but as an example.

After F220 or F230, the control unit 21 gives a code replenishment confirmation notification by the second communication method (F240). Specifically, as an example, not limited, information for confirming to the user of the terminal 20 whether or not to replenish the terminal display code by communicating by the second communication method is displayed on the display unit 24. Let me.

Next, the control unit 21 determines whether or not the code replenishment by the second communication method is selected by the user of the terminal 20 (F250), and if it is determined that it is selected (F250: YES), the second Attempts to communicate using the communication method (F260).

If the communication by the second communication method is successful (F270: YES), the control unit 21 performs the code replenishment process (F280). Specifically, the above-mentioned code replenishment request information is transmitted to the server 10, the terminal display code is acquired from the server 10, and the terminal display code stock data 2831 is stored and replenished. Then, the control unit 21 shifts the processing to F190.

In order to replenish the code by the second communication method, as an example, not limited to, a wireless LAN (for example, WiFi (registered trademark)) which is an example of the second communication method is used as an application that can be linked with the payment application. A search application for searching a place (spot) such as a possible store or facility is downloaded in advance from the terminal 20 and stored in the storage unit 28.

Then, for example, when the user of the terminal 20 selects to perform code replenishment by the second communication method as a result of giving the code replenishment confirmation notification by the second communication method of F240, the control unit 21 sends the terminal 20 to the terminal 20. The stored search application may or may not be started to search for spots that can use the second communication method.
