<System overview>
FIG. 1 is a schematic diagram for explaining the outline of the trading system according to the present embodiment. The trading system according to the present embodiment includes one or a plurality of information processing devices such as a portable information processing device 1 or a stationary information processing device 2, a sales server device 3, and a payment server device 5. There is. The portable information processing device 1 and the stationary information processing device 2 are devices used by the user when purchasing a product. The portable information processing device 1 is, for example, a device such as a portable game device, a mobile phone, a smartphone, a tablet terminal device, or a notebook computer. The stationary information processing device 2 is, for example, a device such as a stationary game device, a desktop personal computer, or a tower type personal computer. The portable information processing device 1 and the stationary information processing device 2 can communicate with the sales server device 3 and the payment server device 5, respectively, via a wired or wireless network. Further, the portable information processing device 1 and the stationary information processing device 2 according to the present embodiment have a non-contact communication function and can communicate with the IC card 7.

In the trading system according to the present embodiment, the sales server device 3 sells goods or rights via a network, and the user uses the portable information processing device 1 or the stationary information processing device 2 to sell the goods or rights. It is a so-called online trading system that makes purchases. That is, in the trading system according to the present embodiment, the seller and the purchaser (consumer) do not face each other, and the consumer uses the portable information processing device 1 or the stationary information processing device 2 to connect to a network such as the Internet. It is a system for purchasing goods or services through the Internet. Therefore, the portable information processing device 1 and the stationary information processing device 2 are not store-installed devices but non-face-to-face devices. That is, the portable information processing device 1 and the stationary information processing device 2 are not devices operated by the seller of the goods or rights, but devices operated by the purchaser of the goods or rights.

The products sold by the sales server device 3 may be various articles such as books or electronic devices that are delivered to the user's home or the like at a later date by mail or the like. Further, the product may be some kind of service provided to, for example, a purchasing user. In addition, the product is digital such as software or data (including item data that can be used only in specific software) that is downloaded to the portable information processing device 1 or the stationary information processing device 2 or another device by purchase. It may be content or various other things.

Further, the right to sell by the sales server device 3 is, for example, a right to use virtual currency in a service such as a virtual currency service in which the server device mainly manages increase / decrease of numerical information (for example, balance information). For example, by giving a virtual currency or points used in a specific sales site or game to the user in an amount corresponding to the consideration (for example, the payment amount of the user), the virtual currency or points The right to use etc. can be sold to the user. In the following, the goods or rights sold by the sales server device 3 are simply referred to as goods.

When the product sold by the sales server device 3 is digital content, the portable information processing device 1 and the stationary information processing device 2 can download and use the purchased digital content. Examples of digital contents include video works such as movies or television broadcasts, games, applications, databases, websites, program software, text data, comics, music, animations, photographs, art, computer graphics or characters. For example, when a video work is purchased as digital content, the portable information processing device 1 or the stationary information processing device 2 downloads the video data of the video work from the sales server device 3 or another server device, and downloads the video data. It is possible to perform a process of playing back and displaying it on a display unit or the like. Digital contents such as video works or music may be provided by so-called streaming distribution. Further, for example, when a game is purchased as digital contents, the portable information processing device 1 or the stationary information processing device 2 can download and execute a game program, data, and the like. As described above, the portable information processing device 1 and the stationary information processing device 2 can perform processing for using the purchased digital contents.

Further, for example, the product sold by the sales server device 3 may be used as a virtual currency. For example, virtual currency includes points and virtual coins that can be used to purchase goods on a specific website, or points and virtual coins that can be used to purchase items or additional scenarios in a specific game. The portable information processing device 1 and the stationary information processing device 2 can purchase virtual currency on the sales server device 3 and purchase products using the virtual currency on a specific website or in a game. ..

Further, in the trading system according to the present embodiment, the user who has purchased the product can use the IC card 7 for payment of the price. The user can charge electronic money or points that can be used for purchasing the product at, for example, a store. The IC card 7 may be used in combination with a card used for payment of a fare in public transportation such as a train or a bus. The IC card 7 stores the balance of charged electronic money or points in an internal memory or the like. The IC card 7 has a non-contact communication function, and can perform payment processing with the payment server device 5 via the portable information processing device 1 or the stationary information processing device 2.

Hereinafter, the case where the user uses the portable information processing device 1 will be described, but the same applies to the case where the stationary information processing device 2 is used. The user who uses online sales first operates the portable information processing device 1 to access the sales server device 3 and performs a login process for this system. By this login process, the trading process by the trading system according to the present embodiment (sales processing by the sales server device 3 and purchase processing by the portable information processing device 1) is started. If the login is successful, information such as a list of products sold is transmitted from the sales server device 3 to the portable information processing device 1, and a list of products that can be purchased is displayed on the display unit of the portable information processing device 1. Will be done. The user operates the portable information processing device 1 to select a product to be purchased, and gives a purchase request to the sales server device 3 (see (1) in the figure). The sales server device 3 to which the purchase request is given from the portable information processing device 1 calculates the total amount of the products to be purchased and transmits the payment request for this amount to the portable information processing device 1 as a payment request. (See (2a) in the figure). The portable information processing device 1 that has received the payment request from the sales server device 3 transmits the received payment request to the payment server device 5 (see (2b) in the figure).

The payment server device 5 that receives the payment request from the portable information processing device 1 communicates with the IC card 7 owned by the user via the portable information processing device 1, and obtains a product from the balance stored in the IC card 7. A process of reducing the amount corresponding to the price (settlement execution process) is performed (see (3a) and (3b) in the figure). (As will be described later, when the balance is stored and managed in the payment server device 5 without storing the balance in the IC card 7, the payment server device 5 does not perform the process of deducting the balance from the IC card 7 here. At this time, the portable information processing device 1 urges, for example, the IC card 7 used for payment to be brought close to a predetermined location of the portable information processing device 1. A message or the like is displayed on the display unit, and non-contact communication with the IC card 7 is performed. The portable information processing device 1 transmits the information received from the payment server device 5 to the IC card 7, and also transmits the information received from the IC card 7 to the payment server device 5. Communication between the payment server device 5 and the IC card 7 via the portable information processing device 1 is performed a plurality of times, whereby the product price is reduced from the balance of the IC card 7.

The payment server device 5 that has completed communication with the IC card 7 transmits the result of the payment process to the portable information processing device 1 (see (4a) in the figure). If the product price can be reduced from the balance of the IC card 7, the result that the payment process is successful is transmitted. On the other hand, if the product price cannot be reduced due to factors such as insufficient balance or communication problems, the result that the settlement process has failed is transmitted. The portable information processing device 1 that has received the payment result from the payment server device 5 transmits the received payment result to the sales server device 3 (see (4b) in the figure). Upon transmission of this settlement result, the settlement process by the trading system according to the present embodiment is completed. The sales server device 3 performs further processing for selling the product based on the payment result received from the portable information processing device 1. For example, if the settlement process is successful, the sales server device 3 determines that the price of the product to be sold has been paid, and proceeds with the sale process to the stage of preparation for shipping the product or permission to download the product. Further, for example, when the payment processing has failed, the sales server device 3 notifies the portable information processing device 1 that the payment processing has failed or that the payment processing is to be performed again. The trading process by the trading system according to the present embodiment is terminated, for example, when the user logs out of the system.

As described above, in the trading system according to the present embodiment, the sales server device 3 and the payment server device 5 do not directly communicate with each other, but communicate with each other via the portable information processing device 1. Therefore, there is no risk that the trading process will fail due to a communication failure between the sales server device 3 and the payment server device 5, and smooth trading processing can be realized. However, this system configuration is an example and is not limited to this. For example, the sales server device 3 directly transmits a payment request to the payment server device 5, the payment server device 5 performs a reduction process of the IC card 7 via the portable information processing device 1, and the payment server device 5 is a sales server. The payment result may be directly transmitted to the device 3. Further, for example, the payment server device 5 may be configured to perform a reduction process of the IC card 7 via the sales server device 3 and the portable information processing device 1. The trading system may have a configuration other than these.

Further, in the trading system according to the present embodiment, the portable information processing device 1 is equipped with a function for preventing unauthorized access (reading / writing of data, etc.) to the IC card 7. In the present embodiment, the stationary information processing device 2 is not equipped with an unauthorized access prevention function. This is because the portable information processing device 1 is easy for the user to carry, and is more likely to be illegally used than the stationary information processing device 2. However, the stationary information processing device 2 may also be configured to be equipped with the same unauthorized access prevention function.

The unauthorized access prevention function included in the portable information processing device 1 according to the present embodiment includes the following three.
(1) Limitation of device posture (2) Limitation of standby time for communication with IC card 7 (3) Limitation of communication distance with IC card 7

The unauthorized access prevention function according to the present embodiment is a function for preventing a malicious user from illegally accessing the IC card 7 of another person by using the portable information processing device 1. The above (1) is a function of restricting the posture, movement, or mounting state (hereinafter, simply referred to as posture) of the portable information processing device 1 when accessing the IC card 7. The portable information processing device 1 has an acceleration sensor and the like, and can detect the posture of its own device. For example, if the housing of the portable information processing device 1 has a substantially rectangular plate shape, access to the IC card 7 is permitted only when the housing is in a substantially horizontal state. As a result, it is possible to limit the posture when a malicious user illegally uses the portable information processing device 1, and it is possible to suppress unauthorized use.

In the above (2), for example, the portable information processing device 1 starts the payment process, displays a message prompting the IC card 7 to come close to a predetermined location on the display unit, and then performs non-contact communication with the IC card 7. It is a function to limit the time to maintain the standby state until is started. The portable information processing device 1 according to the present embodiment has a shorter standby time than the stationary information processing device 2 and the conventional portable information processing device that does not have an unauthorized access prevention function. .. As a result, the time for a malicious user to illegally use the portable information processing device 1 can be shortened, and unauthorized use can be suppressed.

The above (3) is compared with the portable information processing device 1 as compared with the communication distance when, for example, a data storage medium for a game having a non-contact communication function and the portable information processing device 1 perform non-contact communication. This is a function that limits the distance between the IC card 7 and the IC card 7 for non-contact communication related to payment processing. With this function, the user needs to bring the IC card 7 into contact with the portable information processing device 1 or bring it close to the portable information processing device 1 in order to perform payment processing using the IC card 7. As a result, it is possible to prevent a malicious user from using the portable information processing device 1 to illegally access an IC card 7 or the like existing at a remote location.

The portable information processing device 1 according to the present embodiment limits the payment processing due to unauthorized access to the IC card 7 by performing the restriction processing of the above (1) to (3). In the present invention, the "restriction process for restricting payment by (portable information processing apparatus 1) payment process" may be, for example, the following processes (a) to (c).
(a) Prevent the payment process from being executed by preventing the transition to this payment process before the payment process is executed. For example, in the process of requesting the operation for confirming the purchased product, the process of confirming the detection result of the detection unit may be executed so that the operation for confirming the purchased product is not accepted. For example, when the portable information processing device 1 enters the standby state for non-contact communication for non-contact communication with the IC card 7 in response to a read command from the payment server device 5, the standby state is stopped (held). (Including) or termination, and processing that hinders the transition to subsequent payment processing may also be included in the processing of (a).
(b) A process of limiting the payment process by suspending (including holding; the same shall apply hereinafter) or terminating the payment process by executing a process of confirming the detection result of the detection unit during the execution of the payment process. For example, the payment method selection operation may not be accepted by executing the process of confirming the detection result of the detection unit in the process of requesting the operation for selecting the payment method.
(c) The settlement process is restricted by stopping or terminating the settlement process by executing the process of confirming the detection result of the detection unit during the execution of the settlement process. For example, the payment process is stopped or terminated by executing the process of confirming the detection result of the detection unit during the execution of the IC card reading process and / or during the communication for payment with the payment server. The payment process is restricted by letting it.
(d) Processing that restricts payment processing by canceling this payment processing after the payment processing is completed.
In addition to these, after a part of the payment process is performed in the portable information processing device 1, the payment server device 5 or the communication between the portable information processing device 1 and the payment server device 5 is intervened. When another part of the payment process is further executed in the device (hereinafter referred to as "payment server device 5 etc."), in order to prevent the execution of another part of the payment process in the payment server device 5 etc. The process of transmitting information, commands, etc. from the portable information processing device 1 to the payment server device 5 or the like in order to give an opportunity to prevent the payment server device or the like is also the above-mentioned "restriction process for limiting payment by the payment process". include. However, these restriction processes are merely examples, and the present invention is not limited to these, and the settlement process may be restricted by a method other than these. (Processing may be performed to prevent payment from being made by payment processing.)

<Device configuration>
FIG. 2 is a block diagram showing the configuration of the portable information processing device 1. The portable information processing device 1 according to the present embodiment includes a processing unit (processor) 10, a storage unit 11, a storage medium mounting unit 12, a display unit 13, an operation unit 14, a communication unit 15, a non-contact communication unit 16, and a posture. It is configured to include a detection unit 17, a sound output unit 18, and the like. The processing unit 10 of the portable information processing device 1 is configured by using an arithmetic processing unit such as a CPU (Central Processing Unit). The processing unit 10 reads and executes the client program 91a stored in the storage medium 91 mounted on the storage medium mounting unit 12 or the client program 91a stored in the storage unit 11 to purchase and settle the product. It performs various information processing related to the above.

The storage unit 11 is configured by using a volatile or non-volatile semiconductor memory element, a hard disk drive, or the like. The storage unit 11 stores various programs such as the client program 91a and data necessary for executing this program. Further, the storage unit 11 can store the digital contents purchased by the sales server device 3. The storage medium mounting unit 12 is configured so that a storage medium 91 such as a card type, a cassette type, or a disk type can be attached and detached. The processing unit 10 can read the client program 91a and various data from the storage medium 91 mounted on the storage medium mounting unit 12. Further, the processing unit 10 may be configured to be able to write a program, data, or the like to the storage medium 91.

The display unit 13 is configured by using a liquid crystal panel or the like, and displays an image given by the processing unit 10. The operation unit 14 is, for example, a press-type button or a touch panel provided on the display unit 13, and gives a signal to the processing unit 10 according to the content of the operation performed by the user (for example, pressing or releasing the button). The communication unit 15 is a sales server device 3, a payment server device 5, another server device, or another portable type via a network 99 using a wireless signal such as a wireless LAN (Local Area Network) or a mobile phone communication network. Information is sent and received to and from the information processing device 1 and the like. For example, the portable information processing device 1 can communicate with the server device by the communication unit 15, download the client program 91a and the like, and store it in the storage unit 11.

The non-contact communication unit 16 wirelessly transmits and receives non-contact data to and from an IC card 7 or the like by using, for example, a so-called Near Field Communication (NFC) technology. (Note that the "IC card" also includes a so-called "NFC card".) The communication distance of the non-contact communication unit 16 is typically about several mm to several cm. When the user brings the IC card 7 close to the communication distance of the non-contact communication unit 16, non-contact communication between the portable information processing device 1 and the IC card 7 is performed. The non-contact communication unit 16 transmits a signal instructing to read the stored data to the IC tag 70 built in the IC card 7, and receives desired data as a response to the signal. The non-contact communication unit 16 has a function of a so-called IC tag reader. Further, the non-contact communication unit 16 can make the IC tag 70 write the data by transmitting a signal instructing the writing together with the written data. That is, the non-contact communication unit 16 has a function of a writer for an IC tag. Further, the non-contact communication unit 16 has a function of periodically repeating transmission of a wireless signal until a response from the IC card 7 is obtained when an instruction to perform non-contact communication with the IC card 7 is given from the processing unit 10. It has a so-called polling function.

The communication method by the non-contact communication unit 16 is not limited to NFC, and may be various communication methods such as RFID, which are adopted for non-contact communication, short-range wireless communication, and the like. Further, the communication unit 15 and the non-contact communication unit 16 both perform communication using wireless signals, but the frequencies and communication protocols of the wireless signals used are different, and the communication distance of the communication unit 15 is non-existent.

The sales server device 3 that has received the payment result from the portable information processing device 1 updates the payment result of the sales history information 31a of the storage unit 31 to complete payment, payment failure, or processing incomplete based on the received payment result. .. If the settlement result is a successful settlement, the sales processing unit 41 proceeds to the next process of processing the product sales. For example, if the product is digital content, the sales processing unit 41 permits the download of the digital content. After performing the sales processing, the sales processing unit 41 transmits the sales result to the portable information processing device 1. When the portable information processing device 1 receives the sales result from the sales server device 3, the sales and settlement processing of the product by the trading system according to the present embodiment is completed. As a result, transaction processing related to payment is completed between the portable information processing device and the payment server device.

The "payment process" is a process related to the settlement of purchased goods and rights, and is used for communication between the portable information processing device 1 and the payment server device 5 (in addition, the terminal device and the payment server device). Includes processing performed in each of the intervening other terminal devices and server devices). That is, the "payment process" is not necessarily a process performed in cooperation with the portable information processing device 1 and the payment server device 5, but is a process performed in the portable information processing device 1 (locally). It may be a process performed by the payment server device 5. Further, the settlement process may be any process related to the settlement of the goods or rights to be purchased, and may include the process related to the preparation for making the settlement. For example, when reading various data used for making a payment from the IC card 7 (at the request of the payment server device 5), the standby process of waiting until non-contact communication with the IC card 7 becomes possible is also settled. Can be included in the process of preparing to perform (ie, can be included in the settlement process).

In the trading system according to the present embodiment, as a function of preventing unauthorized access of the portable information processing device 1, a process of restricting non-contact communication with the IC card 7 is performed. In the present embodiment, the portable information processing device 1 receives a read command from the payment server device 5, and then transmits the first response by non-contact communication from the IC card 7 to the payment server device 5. Is set as the limit period, and the limit process is performed during this period. In other words, in the trading process and the settlement process according to the present embodiment, there are a limited period (first period) that restricts non-contact communication and a period (second period) that does not restrict other than the restricted period. Is provided.

However, the restriction period shown in FIG. 9 is an example and is not limited to this. For example, the start time of the restriction period is when the portable information processing device 1 transmits a purchase request to the sales server device 3, when the portable information processing device 1 receives a payment request from the sales server device 3, or when the portable information processing device 1 receives a payment request from the sales server device 3. The type information processing device 1 may be at a time when the payment request is transmitted to the payment server device 5, and may be at a time other than these. Further, for example, at the end of the restriction period, the time when the portable information processing device 1 transmits the last response from the IC card 7 to the payment server device 5, or the completion notification from the payment server device 5 is sent by the portable information processing device. It may be the time when 1 is received from the payment server device 5, or the like, and may be a time other than these. Further, in the present embodiment, the portable information processing apparatus 1 imposes three types of restrictions, but different restriction periods may be provided for each.

Further, in the present embodiment, the portable information processing device 1 relays the payment request and the payment result transmitted / received between the sales server device 3 and the payment server device 5, but the present invention is not limited to this. .. The sales server device 3 and the payment server device 5 may be configured to directly send and receive payment requests and payment results without going through the portable information processing device 1.

Further, in the present embodiment, the reduction process is performed by reducing the balance information stored in the IC card 7, but the present invention is not limited to this. For example, the payment server device 5 stores the balance information for each IC card 7, performs non-contact communication with the portable information processing device 1, and based on the card ID obtained from the IC card 7, itself. It may be configured to reduce the amount from the stored balance information. In this case, the payment server device 5 may register the balance information related to the IC card 7 when the IC card 7 is used for the first time, or the balance information is registered before the IC card 7 is used. You may. Further, for example, both the IC card 7 and the payment server device 5 may be configured to store the balance information. In this case, the payment server device 5 can detect unauthorized rewriting of the balance information of the IC card 7 by determining whether or not the balance information of the IC card 7 and the balance information stored by the self-confidence match. ..

When the cancel operation is performed on this screen, the display processing unit 25 returns the display to the payment method selection screen shown in FIG.

When the OK operation is performed on the warning message display screen, the purchase processing unit 26 of the portable information processing device 1 sends a purchase request to the sales server device 3 as shown in FIG. 9, and sells in response to the purchase request. The payment processing unit 21 transmits the payment request given by the server device 3 to the payment server device 5. After that, when a read command is given from the payment server device 5, the payment processing unit 21 of the portable information processing device 1 starts non-contact communication by the non-contact communication unit 16 and performs non-contact communication with the IC card 7. stand by. At this time, the display processing unit 25 displays a standby screen on the display unit 13 for waiting for the user to use the IC card 7.

FIG. 12 is a schematic diagram showing an example of a standby screen displayed by the portable information processing device 1. On the illustrated standby screen, the message "Please touch this screen with the IC card" is displayed. When the user brings the IC card 7 closer to the display unit 13 while the standby screen is displayed, the portable information processing device 1 can perform non-contact communication with the IC card 7 by the non-contact communication unit 16. It becomes. When the cancel operation is performed on the standby screen, the display processing unit 25 returns the display to the payment method selection screen shown in FIG. For communication with the IC card 7 by the non-contact communication unit 16, it is not always necessary to bring the IC card 7 into contact with the display unit 13, and the IC card 7 is brought close to the display unit 13 to the extent that radio waves can reach in both directions. Just attach it. However, in order to make the user easily understand how to use the IC card 7, in the present embodiment, a message prompting the user to operate the display unit 13 of the IC card 7 is displayed on the standby screen.

When it becomes possible to perform non-contact communication with the IC card 7, the portable information processing device 1 relays information exchange between the IC card 7 and the payment server device 5. As a result, the reduction process shown in FIG. 9 is performed. After the reduction processing is completed, in the portable information processing device 1, the payment processing unit 21 notifies the sales server device 3 of the payment result from the payment server device 5, and also notifies the user of the payment result (not shown). ) Is displayed on the display unit 13. Since the settlement result may have various patterns such as success or failure of settlement, the display processing unit 25 displays a message according to the settlement process.

The portable information processing device 1 may output various voice messages by the voice output unit 18 together with the screen display of the display unit 13. Further, the portable information processing device 1 may be configured to output only a voice message by the voice output unit 18 without displaying the screen.

<Posture restriction>
The portable information processing device 1 according to the present embodiment limits the posture of the device when performing non-contact communication with the IC card 7 as a function of preventing unauthorized access to the IC card 7. 13 and 14 are schematic views for explaining the posture restriction by the portable information processing device 1. The portable information processing device 1 according to the present embodiment is assumed to perform non-contact communication with the IC card 7 in a state of being placed on a horizontal surface 100 such as on a desk or a floor.

As shown in the figure, the portable information processing device 1 has a housing having a substantially rectangular plate shape. That is, the housing of the portable information processing device 1 has a shape having two wide surfaces on the front and back surfaces and four peripheral side surfaces. A display unit 13 is provided in the center of one wide surface (this surface is referred to as a surface) of the housing, and one or a plurality of buttons or switches constituting the operation unit 14 are provided around the display unit 13. In the non-contact communication unit 16 of the portable information processing device 1 according to the present embodiment, for example, an antenna for non-contact communication is arranged on the surface of a liquid crystal panel constituting the display unit 13, and a predetermined state is determined from the surface of the display unit 13. Non-contact communication with the IC card 7 can be performed within a range. However, in the portable information processing device 1 according to the present embodiment, radio waves for non-contact communication are shielded from the other wide surface (back surface) and four side surfaces of the housing, and the IC card 7 is brought closer. However, it is configured so that non-contact communication cannot be performed.

The portable information processing device 1 according to the present embodiment can detect the posture of the device by the posture detection unit 17. The posture limiting unit 22 of the portable information processing device 1 allows the non-contact communication unit 16 to perform non-contact communication with the IC card 7 when the posture of the device detected by the posture detection unit 17 is a predetermined posture. When the posture of the device is not a predetermined posture, the posture limiting unit 22 prohibits non-contact communication with the IC card 7. The posture limiting unit 22 can realize the prohibition of non-contact communication by ending or stopping the standby process of waiting for the response from the IC card 7. At this time, the posture limiting unit 22 may completely end the standby process or temporarily suspend the standby process.

In the present embodiment, the posture detection unit 17 is a wide surface of a housing provided with a display unit 13 or the like (that is, a surface for non-contact communication with the IC card 7 or a surface for the user to contact the IC card 7). , Hereinafter referred to as the non-contact communication surface) detects the angle with respect to the gravitational direction. Based on the detection result of the posture detecting unit 17, the posture limiting unit 22 is not connected to the IC card 7 by the non-contact communication unit 16 when the non-contact communication surface of the housing is facing upward and is kept substantially horizontal. Allow contact communication. Specifically, the posture limiting unit 22 is a non-contact communication unit when the non-contact communication surface of the housing faces the direction opposite to the direction of gravity and the angle of the non-contact communication surface is horizontal ± 15 °. The non-contact communication with the IC card 7 by 16 is permitted, and the non-contact communication with the IC card 7 is prohibited when the range is outside the horizontal ± 15 ° range.

In the present embodiment, the posture condition restricted by the posture limiting unit 22 is set so that the non-contact communication surface faces upward and the angle of the non-contact communication surface is within a range of horizontal ± 15 °. This condition is a condition set for determining that the portable information processing apparatus 1 having the shapes shown in FIGS. 13 and 14 is placed on a horizontal surface. Therefore, the condition of the posture to be restricted is an appropriate condition that can determine that the housing is placed on a horizontal place according to the shape of the housing of the portable information processing device 1. Can be set.

For example, the IC card 7 may be placed on a horizontal surface, and the posture may be restricted on the condition that the portable information processing device 1 is placed on the IC card 7. In this case, the attitude limiting unit 22 makes a determination on the condition that, for example, the non-contact communication surface faces the direction of gravity (that is, downward) and the non-contact communication surface is within the horizontal ± 15 ° range. It can be configured.

The posture limiting unit 22 of the portable information processing device 1 has a posture after the operation detecting unit 30 detects that a predetermined operation, for example, an OK operation has been performed on the operation unit 14 on the warning message display screen shown in FIG. The acquisition of the detection result of the detection unit 17 and the determination of the posture based on the acquired detection result are started. In the portable information processing device 1, after the start of processing such as determination by the posture limiting unit 22, the settlement processing unit 21 starts non-contact communication by the non-contact communication unit 16, and the display processing unit 25 waits as shown in FIG. The screen is displayed on the display unit 13. While the standby screen is displayed, the posture limiting unit 22 continuously acquires the detection result of the posture detecting unit 17 and determines the posture based on the acquired detection result. During this period, the non-contact communication unit 16 continuously detects the IC card 7 by polling.

When it is determined that the posture of the device is the predetermined posture, the posture limiting unit 22 performs the portable information processing device 1 until the non-contact communication unit 16 starts the non-contact communication with the IC card 7. The standby state of non-contact communication with the IC card 7 (for example, the state of polling) is maintained. As a result, as shown in FIG. 12, the state in which the standby screen is displayed on the display unit 13 of the portable information processing apparatus 1 is maintained.

On the other hand, when it is determined that the posture of the device is not a predetermined posture, the posture limiting unit 22 interrupts the standby state of non-contact communication with the IC card 7. That is, the posture limiting unit 22 stops polling by the non-contact communication unit 16. As a result, the payment processing unit 21 of the portable information processing device 1 stops the non-contact communication by the non-contact communication unit 16. Further, the display processing unit 25 returns the display of the display unit 13 from the standby screen shown in FIG. 12 to the warning message display screen shown in FIG. As a result, the portable information processing device 1 requests a predetermined operation on the warning message display screen (for example, an operation of selecting OK again on the warning message display screen), and when the user accepts the predetermined operation, the IC card 7 The standby processing restart unit 27 of the processing unit 10 restarts the standby processing of the non-contact communication with. The method of requesting a predetermined operation from the user is not limited to this method, and for example, the user is urged to put the portable information processing device 1 in a predetermined posture, a stationary state (described later), or the like. A message (different from the warning message display screen shown in FIG. 11) may be displayed.

FIG. 15 is a flowchart showing a procedure of posture restriction processing by the portable information processing device 1. The processing unit 10 of the portable information processing device 1 displays a warning message display screen on the display processing unit 25 when electronic money is selected as the payment method on the payment method selection screen shown in FIG. 10, for example. The process of displaying in 13 is performed (step S1). The processing unit 10 determines whether or not the OK operation has been performed on the warning message display screen (step S2). If the OK operation has not been performed (S2: NO), the processing unit 10 returns the processing to step S1 and continues to display the warning message display screen.

When the OK operation is performed (S2: YES), the processing unit 10 performs a process of displaying the standby screen on the display unit 13 by the display processing unit 25 (step S3). Next, the posture limiting unit 22 of the processing unit 10 acquires the device attitude detected by the attitude detecting unit 17 (step S4). The posture limiting unit 22 determines whether or not the acquired posture is a predetermined posture (step S5). When the device posture is not a predetermined posture (S5: NO), the posture limiting unit 22 interrupts the standby state for non-contact communication with the IC card 7 (step S6), returns the processing to step S1, and returns the processing to the display processing unit. The display process on the display unit 13 of the warning message display screen by 25 is performed. When the device posture is a predetermined posture (S5: YES), the posture limiting unit 22 determines whether or not the non-contact communication with the IC card 7 by the non-contact communication unit 16 has been started (step S7). When the non-contact communication has not been started (S7: NO), the posture limiting unit 22 returns to step S3 and continues to display the standby screen. When the non-contact communication is started (S7: YES), the posture limiting unit 22 ends the posture limiting process.

(Modification example 1)
In the present embodiment, the posture limiting unit 22 is configured to limit non-contact communication with the IC card 7 when the non-contact communication surface of the housing is not within the horizontal ± 15 ° range. Is not limited to this. (Also, it does not have to be ± 15 °, and may be ± any number of times as long as it can be said to be in a substantially horizontal state.) For example, the posture limiting unit 22 is a housing of the portable information processing device 1. It can be configured to limit depending on whether or not the body is in a stationary state. The posture limiting unit 22 according to the first modification is based on the posture first acquired from the posture detecting unit 17 after the OK operation is performed on the warning message display screen and the state shifts to the standby state. After that, the posture limiting unit 22 repeatedly acquires the detection result of the posture detecting unit 17, and when the change in posture from the reference posture exceeds the threshold value (predetermined limit), the posture limiting unit 22 waits for non-contact communication with the IC card 7. Suspend the state.

Furthermore, the posture restriction unit 22 may be configured to perform posture restriction processing under various conditions. For example, the posture limiting unit 22 detects the posture at a predetermined cycle instead of changing from the reference posture, and interrupts the standby state of non-contact communication when the difference between the previous posture and the current posture exceeds the threshold value. May be. That is, the posture limiting unit 22 may be configured to interrupt the standby state when the movement of the portable information processing device 1 exceeds a predetermined limit.

Further, for example, the portable information processing device 1 may be configured to perform posture detection and posture restriction based on an captured image of a camera, an image sensor, or the like. In this case, the posture limiting unit 22 compares a plurality of images obtained by periodically performing imaging, calculates the displacement amount of the object captured in the image by image processing, and compares it with the threshold value. Can be configured to perform.

Further, for example, when a camera is mounted on the back surface of the housing of the portable information processing device 1, the portable information processing device 1 described above indicates that the desk surface, the floor surface, or the like is imaged by the camera. It may be added to the condition for determining that the product is placed on a surface, floor surface, or the like.

Further, for example, the posture may be restricted on the condition that the non-contact surface of the housing is maintained in a substantially horizontal state for a predetermined period. For example, the portable information processing device 1 confirms that a substantially horizontal state is maintained for a predetermined period (for example, 15 seconds) after an OK operation is performed on the warning message display screen, and then non-contact communication is performed. The configuration may be such that the unit 16 starts communication with the IC card 7.

In the present embodiment, the posture limiting unit 22 limits the posture in the settlement processing performed by the settlement processing unit 21. The posture restriction unit 22 does not restrict processing (non-payment processing) other than the payment processing performed by the purchase processing unit 26. The portable information processing device 1 may be configured so that the posture detection unit 17 does not detect the posture during the non-payment processing, and the posture detection unit 17 detects the posture but processes the detection result. The configuration may be such that the posture detection unit 17 does not notify the 10th, the processing unit 10 ignores the detection result notified by the posture detection unit 17, or the posture restriction unit 22 determines the posture condition based on the detection result. The configuration may not be performed.

<Waiting time limit>
The portable information processing device 1 according to the present embodiment limits the waiting time until the start of non-contact communication with the IC card 7 as an unauthorized access prevention function for the IC card 7. As shown in FIG. 9, in the trading system according to the present embodiment, a standby time is specified when a read command of the IC card 7 is given from the payment server device 5 to the portable information processing device 1 or the stationary information processing device 2. I do. In the present embodiment, the standby time specified by the payment server device 5 is the same time regardless of whether the payment processing partner is the portable information processing device 1 or the stationary information processing device 2, and is, for example, 60 seconds. can do.

When the payment server device 5 gives the designation of the standby time, the stationary information processing device 2 waits for the non-contact communication with the IC card 7 for the designated standby time. If the non-contact communication with the IC card 7 is not performed within this standby time, the stationary information processing device 2 interrupts the payment process. Further, the payment server device 5 interrupts the payment process when a response from the stationary information processing device 2 is not obtained within the designated standby time.

On the other hand, in the portable information processing device 1 according to the present embodiment, a time shorter than the waiting time designated by the payment server device 5 is set as a waiting time for waiting for non-contact communication with the IC card 7. .. For example, the standby time specified by the server device 5 is 60 seconds, whereas the standby time of the portable information processing device 1 can be set to 30 seconds. The standby time of the portable information processing device 1 may be a time determined in advance in the trading system, or may be a time calculated by calculation such as 50% of the standby time specified by the server device 5.

The time limit unit 23 of the portable information processing device 1 selects electronic money on the payment method selection screen shown in FIG. 10, and then performs an OK operation on the warning message display screen of FIG. 11 which is displayed. Start timing the waiting time. The time limit unit 23 continuously clocks the standby time while the standby screen shown in FIG. 12 is displayed on the display unit 13. If the non-contact communication with the IC card 7 is not performed within the standby time, the time limit unit 23 interrupts the payment process. When the payment process is interrupted, the portable information processing device 1 according to the present embodiment returns the display of the display unit 13 to the payment method selection screen shown in FIG. That is, when the payment process is interrupted, the payment processing unit 21 of the portable information processing device 1 according to the form returns the transaction processing to the stage of selecting the payment method.

The portable information processing device 1 displays a product selection screen (not shown) displaying a list of products that can be purchased, for example, at a stage prior to the payment method selection screen, and a user can select a product. The trading process may be returned to the stage of accepting. The portable information processing device 1 returns the trading process to a stage that requires at least one operation reception by the user before reaching the stage of performing non-contact communication with the IC card 7.

FIG. 16 is a flowchart showing a procedure of standby time limitation processing by the portable information processing apparatus 1. Note that this flowchart partially overlaps with the flowchart shown in FIG. Of the entire payment processing performed by the portable information processing device 1, the flow chart of FIG. 16 extracts the processing related to the time limit, and the flowchart of FIG. 15 extracts the processing related to the posture restriction. Because there is. Actually, the portable information processing device 1 simultaneously performs the processes shown in FIGS. 15 and 16 as one payment process.

The processing unit 10 of the portable information processing device 1 performs a process in which the display processing unit 25 displays the payment method selection screen shown in FIG. 10 on the display unit 13 (step S11). The processing unit 10 determines whether or not electronic money has been selected as the payment method on the payment method selection screen (step S12). When the electronic money is not selected (S12: NO), the processing unit 10 returns the processing to step S11 and continues to display the payment method selection screen. The description of the processing when another payment method is selected on the payment method selection screen will be omitted.

When electronic money is selected on the payment method selection screen (S12: YES), the processing unit 10 performs a process of displaying the warning message display screen on the display unit 13 on the display processing unit 25 (step S13). The processing unit 10 determines whether or not the OK operation has been performed on the warning message display screen (step S14). If the OK operation has not been performed (S14: NO), the processing unit 10 returns the processing to step S13 and continues to display the warning message display screen.

When the OK operation is performed (S14: YES), the standby time limiting unit 23 of the processing unit 10 starts timing the predetermined standby time by using, for example, a built-in timer function (step S15). Further, the processing unit 10 performs a process of displaying the standby screen on the display unit 13 by the display processing unit 25 (step S16). The standby time limiting unit 23 determines whether or not a predetermined standby time (for example, 30 seconds) has elapsed from the start of time counting in step S15 (step S17). When the waiting time has elapsed (S17: YES), the waiting time limiting unit 23 returns the processing to step S11 and returns the payment processing stage to the display of the payment method selection screen. At this time, the processing unit 10 may display the payment method selection screen after displaying an error message or the like.

When the standby time has not elapsed (S17: NO), the standby time limiting unit 23 determines whether or not the non-contact communication with the IC card 7 by the non-contact communication unit 16 has been started (step S18). When the non-contact communication is not started (S18: NO), the standby time limiting unit 23 returns the process to step S16 and continues to display the standby screen. When the non-contact communication is started (S18: YES), the standby time limiting unit 23 ends the standby time limiting process.

Further, as a method of limiting the standby time for non-contact communication with the IC card 7 by the portable information processing device 1, the methods shown in the following modifications 2 to 3 can be adopted.

(Modification 2)
The portable information processing device 1 according to the second modification changes the standby time according to the type of the application program executed by the processing unit 10. In the portable information processing device 1 according to the present embodiment, in addition to the client program 91a for using the online trading system, the processing unit 10 transmits various application programs stored in the storage unit 11 or the storage medium 91. Can be executed. The portable information processing device 1 can perform information processing related to a game by, for example, executing a game program. In this case, the portable information processing device 1 can realize a game using a data storage medium such as an IC card or a figure in which an IC tag is embedded.

The portable information processing device 1 according to the second modification is an application program (non-contact with the data storage medium) executed by the processing unit 10 when the non-contact communication unit 16 performs non-contact communication with the data storage medium. The waiting time for non-contact communication with the data storage medium is changed according to the application program that requested the communication). For example, the portable information processing device 1 stores a table or the like in which an application program and a waiting time are associated with each other in a storage unit 11, and determines the waiting time by referring to this table based on the running application program. can do. As the standby time, a short time (for example, 30 seconds) is set for the application program that performs payment processing with the payment server device 5, and a long time (for example, 60 seconds) is set for the application program that does not perform payment processing. do.

(Modification example 3)
The portable information processing device 1 according to the third modification changes the standby time according to the processing content even in the non-contact communication with the IC card 7 according to one client program 91a. The portable information processing device 1 that executes the client program 91a can perform payment processing with the payment server device 5 as described above by non-contact communication with the IC card 7, and for example, inquires about the balance of the IC card 7. As described above, processing that does not require communication with the payment server device can be performed. The portable information processing device 1 according to the third modification sets the standby time in the case of non-contact communication with the IC card 7 when performing payment processing with the payment server device 5 to a short time, and is other than the payment processing. The standby time in the case of non-contact communication with the IC card 7 is set to a long time.

(Modification example 4)
The portable information processing device 1 according to the fourth modification changes the standby time according to the type of data storage medium that performs non-contact communication. For example, when IC cards 7 that can be used for payment processing by electronic money are provided by a plurality of companies, the portable information processing device 1 uses contactless communication depending on which company's IC card 7 is used for payment processing. Change the waiting time of.

The portable information processing device 1 according to the modification 4 has an IC card 7 such as "electronic money of company A" and "electronic money of company B" on the payment method selection screen displayed on the display unit 13 in the payment process. Display the options for each provider. By operating the operation unit 14 of the portable information processing device 1, the user selects the provider of the IC card 7 to be used from the options displayed on the payment method selection screen. In the portable information processing device 1, the waiting time is set for each provider of the IC card 7, and the waiting time is determined according to the user's selection.

Further, in addition to the above-mentioned limitation of the standby time, the portable information processing apparatus 1 (or separately) relates to a time for maintaining non-contact communication with the IC card 7 as shown in the following modification 5. Limits may be set.

(Modification 5)
The portable information processing device 1 according to the modification 5 is in a state where non-contact communication with the IC card 7 is possible for a predetermined time as a condition for starting the payment process with the payment server device 5 using the IC card 7. It is required to be maintained for (for example, 30 seconds). The portable information processing device 1 according to the modified example 5 has a predetermined cycle (for example, 1 second) when the non-contact communication unit 16 enables non-contact communication with the IC card 7 within the above-mentioned standby time. It is determined whether or not non-contact communication with the IC card 7 is possible once (such as once). When the portable information processing device 1 determines that non-contact communication with the IC card 7 is possible continuously for a predetermined number of times (for example, 30 times), the portable information processing device 1 proceeds to the next stage of the payment process.

FIG. 17 is a flowchart showing a procedure of processing performed by the portable information processing apparatus 1 according to the modified example 5. The process shown in this flowchart is, for example, a process performed following FIGS. 15 and 16. Further, in this processing, a counter for counting the number of times the determination is made is used, and this counter is realized by using, for example, an internal memory of the processing unit 10 or a part of the storage area of the storage unit 11.

The processing unit 10 of the portable information processing apparatus 1 according to the modification 5 first initializes the counter value to 0 (step S21). Next, the processing unit 10 performs non-contact communication with the IC card 7 at the non-contact communication unit 16 (step S22). The processing unit 10 determines whether or not communication with the IC card 7 is possible from the result of the non-contact communication in step S22 (step S23). When communication with the IC card 7 is impossible (S23: NO), the processing unit 10 interrupts the payment process (step S24) and ends the process.

When communication with the IC card 7 is possible (S23: YES), the processing unit 10 adds 1 to the value of the counter (step S25). Next, the processing unit 10 determines whether or not the value of the counter exceeds 30 (step S26). If the value of the counter does not exceed 30 (S26: NO), the processing unit 10 returns the processing to step S22. When the value of the counter exceeds 30 (S26: YES), the processing unit 10 performs the subsequent settlement processing (step S27), and ends the processing.

<Communication distance limit>
The portable information processing device 1 according to the present embodiment limits the distance at which non-contact communication with the IC card 7 is possible as a function of preventing unauthorized access to the IC card 7. For example, in non-contact communication by NFC or the like, it is not necessary to bring the IC card 7 into contact with the housing of the portable information processing device 1, and communication can be performed even at a distance of about several cm from the housing. When the portable information processing device 1 according to the present embodiment performs payment processing with the payment server device 5, the non-contact communication is performed by reducing the strength of the wireless signal output by the non-contact communication unit 16. Make the distance that can be done shorter than usual. For example, the portable information processing device 1 reduces the strength of the wireless signal when performing non-contact communication in the payment process to about 50% with respect to the strength of the wireless signal when performing non-contact communication in the payment process.

The non-contact communication unit 16 of the portable information processing device 1 according to the present embodiment can change the strength of the wireless signal in response to a command from the processing unit 10. The non-contact communication unit 16 changes the strength of the radio signal in two steps, for example. The communication distance limiting unit 24 of the processing unit 10 issues a command to the non-contact communication unit 16 to reduce the strength of the wireless signal when performing non-contact communication with the IC card 7 in response to a read command from the payment server device 5. give. As a result, the strength of the wireless signal output by the non-contact communication unit 16 is reduced, and the distance between the portable information processing device 1 and the IC card 7 that can be contactlessly communicated is shortened.

FIG. 18 is a flowchart showing a procedure of communication distance limitation processing by the portable information processing device 1. The communication distance limiting unit 24 of the processing unit 10 of the portable information processing device 1 determines whether or not an access request (that is, a read command) to the IC card 7 is given from the payment server device 5 (step S31). When the request from the payment server device 5 is not given (S31: NO), the communication distance limiting unit 24 waits until the request is given. When the request from the payment server device 5 is given (S31: YES), the communication distance limiting unit 24 gives an instruction to reduce the signal strength to the non-contact communication unit 16 (step S32).

After that, the communication distance limiting unit 24 determines whether the payment process using the IC card 7 is completed (step S33). The termination of the settlement processing here includes not only the normal termination of the settlement processing but also the abnormal termination such as the interruption of the settlement for some reason. When the settlement process is not completed (S33: NO), the communication distance limiting unit 24 waits until the settlement process is completed. When the settlement process is completed (S33: YES), the communication distance limiting unit 24 gives a command to the non-contact communication unit 16 to return the signal strength to the original strength (step S34), and ends the process.

Although the non-contact communication between the portable information processing device 1 and the IC card 7 is performed a plurality of times in one payment process, the communication distance limiting unit 24 limits the first non-contact communication. The configuration may be such that the second and subsequent non-contact communications are not restricted. Further, as a method of limiting the distance capable of non-contact communication with the IC card 7, in addition to the method of reducing the strength of the radio signal output by the non-contact communication unit 16 as described above, for example, the following modification 6 The method shown in the above can also be adopted.

(Modification 6)
The non-contact communication unit 16 of the portable information processing device 1 according to the sixth modification has a function of measuring the signal strength of the wireless signal when the wireless signal related to the non-contact communication is received from the IC card 7. There is. When the non-contact communication unit 16 receives the wireless signal from the IC card 7, the non-contact communication unit 16 gives the data related to the wireless signal to the processing unit 10 and notifies the processing unit 10 of the measured signal strength.

The communication distance limiting unit 24 of the processing unit 10 determines whether or not the signal strength notified from the non-contact communication unit 16 exceeds the threshold value. If the signal strength does not exceed the threshold value, the communication distance limiting unit 24 invalidates the received signal and does not perform payment processing based on the data from the IC card 7 included in the received signal. When the signal strength exceeds the threshold value, the communication distance limiting unit 24 makes the received signal valid and performs the settlement process.

FIG. 19 is a flowchart showing a procedure of communication distance limitation processing by the portable information processing device 1 according to the modified example 6. The non-contact communication unit 16 of the portable information processing device 1 according to the sixth modification determines whether or not a wireless signal from the IC card 7 has been received (step S41). When the radio signal is not received (S41: NO), the non-contact communication unit 16 waits until the radio signal is received. When the radio signal is received (S41: YES), the non-contact communication unit 16 measures the signal strength of the received radio signal (step S42).

The communication distance limiting unit 24 of the processing unit 10 of the portable information processing device 1 determines whether or not the signal strength measured by the non-contact communication unit 16 exceeds a predetermined threshold value (step S43). When the signal strength exceeds the threshold value (S43: YES), the communication distance limiting unit 24 validates the signal received by the non-contact communication unit 16 (step S44), and makes a payment process using the data included in the received signal. (Step S45), and the process is returned to step S41. When the signal strength does not exceed the threshold value (S43: NO), the communication distance limiting unit 24 invalidates the signal received by the non-contact communication unit 16 (step S46), and proceeds to step S41 without performing the settlement process. return.

<Summary>
In the trading system according to the present embodiment, the portable information processing device 1 or the stationary information processing device 2 and the server device 5 communicate with each other, and the settlement processing related to the goods sold and sold via the sales server device 3 is performed by the IC. The configuration is performed using the card 7. The portable information processing device 1 according to the present embodiment includes a non-contact communication unit 16 that performs non-contact communication with the IC card 7, and also has a function of preventing unauthorized data acquisition from the IC card 7. ..

The portable information processing device 1 according to the present embodiment includes a posture detection unit 17 that detects the posture of the device using an acceleration sensor, a gyro sensor, or the like. The posture limiting unit 22 of the portable information processing device 1 limits the settlement process when the posture detected by the posture detecting unit 17 does not satisfy a predetermined posture condition. At this time, the posture limiting unit 22 limits the settlement process by limiting the data acquisition by non-contact communication from the IC card 7. As a result, the posture of the device when performing payment processing using the IC card 7 can be restricted, so that a malicious user illegally uses the portable information processing device 1 to use the IC card of another user. It is possible to prevent 7 from being used for own settlement without permission.

Further, the portable information processing device 1 makes a payment based on the posture detected by the posture detection unit 17 after the non-contact communication with the IC card 7 is completed in the payment processing, for example, after the reduction processing shown in FIG. 9 is completed. No processing restrictions are applied. By limiting the posture restriction when performing non-contact communication with the IC card 7, it is possible to suppress the reduction in convenience of the portable information processing device 1 due to the posture restriction.

Further, the display processing unit 25 of the portable information processing device 1 displays an image prompting the posture of the own device to satisfy the posture condition, for example, the warning message display screen shown in FIG. 11 on the display unit 13. Further, the portable information processing device 1 displays a warning message display screen on the display unit 13 when the posture restriction unit 22 restricts the payment process. As a result, it is possible to notify the user that the portable information processing device 1 needs to satisfy the posture condition in order to perform the payment processing.

Further, the posture limiting unit 22 of the portable information processing device 1 limits the payment processing on the condition that the own device is placed on a substantially horizontal plane as a posture condition. For example, the posture limiting unit 22 performs payment processing on the condition that the surface of the housing of the portable information processing device 1 that performs non-contact communication with the IC card 7 is substantially horizontal (within a range of horizontal ± 15 °). Limit. As a result, the portable information processing device 1 cannot be used for payment processing in a posture such as substantially vertical, so that unauthorized use of the portable information processing device 1 by a malicious user can be suppressed.

Further, the posture limiting unit 22 of the portable information processing device 1 may limit the payment processing on the condition that the own device is in a substantially stationary state. For example, the posture limiting unit 22 can make the posture condition in a substantially stationary state that the change in the posture detected by the posture detecting unit 17 does not exceed the threshold value. This makes it difficult to carry out payment processing while carrying the portable information processing device 1, so that unauthorized use of the portable information processing device 1 by a malicious user can be suppressed.

Further, the portable information processing device 1 and the stationary information processing device 2 may have a configuration capable of performing information processing related to a game by executing a game program. That is, the portable information processing device 1 and the stationary information processing device 2 may be a portable game device and a stationary game device. By equipping the game device with a function for performing payment processing using the IC card 7, the user can purchase a game program or an item in the game using the IC card 7, which is convenient for the game device. The sex can be improved.

Further, the IC card 7 may be shared with an IC card that can be used for fare payment of transportation such as a train or a bus. As a result, the user does not need to have a dedicated IC card for payment of the online trading system, and the convenience of using the system can be improved.

Further, in the portable information processing device 1 and the stationary information processing device 2, for example, after performing an OK operation on the warning message display screen shown in FIG. 11, the non-contact communication unit 16 performs non-contact communication with the IC card 7. If contactless communication is not performed within this waiting time, the payment process is interrupted. In the trading system according to the present embodiment, the standby time is set to be different between the portable information processing device 1 and the stationary information processing device 2. For example, the standby time of the portable information processing device 1 is shorter than the standby time of the stationary information processing device 2. Further, the payment server device 5 specifies the standby time for the portable information processing device 1 and the stationary information processing device 2. However, in the present embodiment, a time shorter than the waiting time specified by the payment server device 5 is set as the waiting time of the portable information processing device 1. As a result, it is possible to suppress unauthorized use of the portable information processing device 1 and prevent the convenience of the stationary information processing device 2 which is difficult to be illegally used from being lowered.

Further, the portable information processing device 1 displays a screen for accepting input from the user on the display unit 13 before the stage of performing non-contact communication with the IC card 7 in the payment process, and accepts the input on this screen. Later, it shifts to the stage of performing non-contact communication. If the payment process fails after that, the portable information processing device 1 returns the display to the input reception screen. The input reception screen may be, for example, the payment method selection screen shown in FIG. 10, the screen for selecting the product before that, or the like. This makes it difficult to continuously attempt non-contact communication with the IC card 7, so that unauthorized use of the portable information processing device 1 can be suppressed.

Further, the portable information processing device 1 acquires data from the IC card 7 and performs payment processing when the state in which the non-contact communication unit 16 can perform non-contact communication with the IC card 7 is maintained for a predetermined time. I do. As a result, it is necessary to keep the IC card 7 close to the portable information processing device 1 for a long time, so that unauthorized use of the portable information processing device 1 can be suppressed.

Further, the payment server device 5 stores the payment history information 51a in the storage unit 52, and the payment history information 51a includes information related to the correctness of the payment process. By storing such a history, it is possible to later search for information on a user who has attempted unauthorized use, a portable information processing device 1, or the like.

Further, the portable information processing device 1 performs wireless communication at the communication unit 15 over a distance longer than the communication distance between the non-contact communication unit 16 and the IC card 7. The portable information processing device 1 communicates with the server device 5 by wireless communication of the communication unit 15. This makes it possible to improve the convenience of the portable information processing device 1.

Further, the portable information processing device 1 limits the communication distance of the non-contact communication when performing the non-contact communication with the IC card 7 regarding the payment processing. For example, the communication distance limiting unit 24 of the portable information processing device 1 can shorten the communication distance of non-contact communication by reducing the strength of the wireless signal output by the non-contact communication unit 16. Further, for example, the communication distance limiting unit 24 measures the strength of the received signal from the IC card 7 and invalidates the received signal when the strength does not exceed the threshold value, thereby shortening the communication distance of non-contact communication. Can be done. As a result, it is necessary to bring the IC card 7 closer to the portable information processing device 1 at the time of payment processing, so that unauthorized use of the portable information processing device 1 can be suppressed.
