Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a communication line,
Suitable for applications such as selling tickets and coupons, and for managing entry (exit) to a certain place,
The present invention relates to a portable terminal device having a recognition code display function and a program therefor.

[0002]

2. Description of the Related Art Recently, mobile phones and PDAs (Personal Digital Assistants) having a communication environment and an Internet connection environment have been developed.
With the advent of mobile terminal devices such as Assistants), services have been provided such that a clerk checks the ticket displayed on the screen of the mobile terminal device and permits entry into the event venue. This eliminates the need for a conventional ticket or coupon ticket sales counter or store, reduces the burden on the parties involved in holding the event, and facilitates information management.

[0003] Taking a step further, a system that displays a recognition code such as a bar code on a screen of a portable terminal device, reads the code with a bar code reader, and realizes a service defined in the bar code has appeared. For example, it can be used for services such as entrance check-in for movie previews, event information such as bargains and concerts at department stores.

[0004]

However, the display screens of the portable terminal devices have different resolutions, respectively.
Various measures have been devised for each maker in order to improve visibility, and there are types that are easy to read with a barcode reader and types that are difficult to read, and are not practical because of lack of uniformity. That is, since barcode reading is not performed well, for example, when the barcode is used for checking the entrance to the event venue, it is expected that the staff will be confused to check the ticket. When a barcode is displayed on the screen of the mobile terminal device, the data may be transferred to a third party by e-mail or the like. That is, the same barcode can be displayed on the transferred third-party mobile terminal device. In this case, it is necessary to give consideration to misuse, such as diversion and tampering.

On the other hand, recently, in a foldable mobile phone model whose main display screen is openable and closable through a hinge mechanism with respect to a main body portion including a key switch, a folded date and time of a date and Time display, missed call display,
A small-screen private window, that is, a sub-screen, which allows the user to check the telephone status such as the number and name of the other party at the time of an incoming call, has appeared. We displayed the barcode on this subscreen and read it, and obtained experimental results that barcode reading was easier than on the main display screen. In addition, since this sub-screen has not been widely used, it has been concluded that standardization is easy.

An object of the present invention is to pay attention to the characteristics of the above-described sub-screen, display a recognition code represented by a bar code or the like on the sub-screen, and make it difficult to transfer or falsify to a third party. It is an object of the present invention to provide a portable terminal device with a recognition code display function and a program therefor.

[0007]

[MEANS FOR SOLVING THE PROBLEMS] (Portable terminal device) In order to solve the above-mentioned problems, the invention according to claim 1 is a portable terminal having a recognition code display function connected to a recognition code distribution server via a communication line. A terminal device, which is provided independently of a main display screen and includes a dedicated sub-screen for displaying a recognition code distributed from the recognition code distribution server.

[0008] The invention described in claim 2 is the first invention.
In the portable terminal device with a recognition code display function according to the above, in order to display a recognition code on the sub-screen, a recognition code requesting unit that requests the recognition code distribution server to distribute a recognition code, and the recognition code And a recognition code display control means for displaying the code on the sub-screen when it is received.

Further, the invention according to claim 3 is the invention according to claim 2.
3. In the portable terminal device with a recognition code display function described in 1., the recognition code deletion data received after the recognition code is used is displayed on the sub-screen and / or the received recognition code is deleted. Means,
It is characterized by having.

In the above configuration, for example, the user accesses the site to request the download of the recognition code, and when the response returns, displays it on the sub screen instead of the main display screen. For this purpose, for example, the data of the header part (main screen display prohibition flag) attached to the recognition code is read to prohibit display on the main display screen, or different telephone numbers are used for the main display screen and the sub screen. It is conceivable to connect the sub-screen with the recognition code distribution server. Further, the recognition code displayed on the sub-screen is read by the barcode reader, and after executing the defined service, the recognition code is deleted based on the deletion data transmitted from the recognition code distribution server.

As a result, since the recognition code is received so as to be displayed on the sub-screen, unlike the main display screen, it is difficult to transfer the recognition code to a third party or falsify the contents. That is, it is difficult to perform an unauthorized operation such as transferring the recognition code received from the recognition code distribution server to a third party or falsifying the content. Further, the problem of inconsistency in reading barcodes is eliminated as compared with the main display screen. In other words, as for the sub screen, there are few models currently installed,
In addition, since a high-level display is not required at present, it is easy to unify specifications unlike the main screen, thereby improving bar code readability.

Hereinafter, the operation of the embodiment of the present invention shown in FIGS. 1 to 5 will be described in detail with reference to FIGS. 6 to 8.

First, the operation sequence of the portable terminal device 3 and the recognition code distribution server 1 will be described using the operation sequence chart shown in FIG. First, the mobile terminal device 3
To perform the site access of the recognition code distribution server 1 (step S61). Upon receiving this, the recognition code distribution server 1 performs a recognition code distribution process, and distributes the recognition code to the portable terminal device 3 that has made the request (step S62). When there is a request for delivery of search data other than the recognition code, the search result is delivered similarly. The portable terminal device 3 that has received the distribution of the data, if it is a kind of the ordinary search data, is the main LC
If D is the recognition code, it is displayed on the sub LCD 43 (step S63). For this purpose, when the recognition code distribution server 1 distributes the recognition code to the portable terminal device 3, a header of at least one bit is added to the beginning of the recognition code, and the portable terminal device 3 detects the header. Display on the main LCD 42 is prohibited and the sub LC
It is necessary to display on D43. Or the main L
A different telephone number is assigned to each of the CD 42 and the sub LCD 23, and the sub LCD 4 of the portable terminal device 3 requested when the recognition code distribution server 1 distributes the recognition code.
3 may be connected.

The recognition code displayed on the sub LCD 43 in this manner is read by, for example, a bar code reader provided in the ticket issuing terminal 2 shown in FIG. 1 (step S64). As a result, the mobile terminal device 3
Sends the used data to the recognition code distribution server 1 and requests transmission of the deleted data. Upon receiving this, the recognition code distribution server 1 generates deletion data (step S65), and transmits the data to the portable terminal device 3 that has made the request. The mobile terminal device 3 receives the deletion data and deletes the recognition code displayed on the sub LCD 43 according to the deletion data (step S66). In addition, sub LCD
The timing of deleting the recognition code displayed at 43 differs depending on the application. For example, in the case of a ticket, it is immediately after the reading is completed, and in the case of a commuter pass, it is after the period expires.

The detailed operation of the portable terminal device 3 will be described with reference to the operation flowchart of the portable terminal device 3 shown in FIG. The user operates the mobile terminal device 3 to access the site of the authentication code distribution server 1 (step S71). Further, a downline load request (DLL; Down) for the recognition code or the search data
Line Load) is performed (step D72). This is performed by the recognition code request unit 303. If the data obtained from the recognition code distribution server 1 is the recognition code (step S73), that is, if the header added to the head of the data indicates that the data is the recognition code, the data, that is, The recognition code is displayed on the sub LCD 43 (step S74). If it is not a recognition code, it is displayed on the main LCD 42 (step S75). this is,
The recognition code display control unit 304 executes.

Here, it is assumed that the recognition code is discriminated on the side of the portable terminal device 3 and the display on the sub LCD 43 is controlled.
The identification code may be displayed directly on the sub LCD 43 by directly connecting the call to the telephone number dedicated to the incoming call attached to D43 and distributing. Next, the sub LCD 43
Is read by the bar code reader (step S76), and after it is used (step S76).
77), receives the deletion data transmitted from the recognition code distribution server 1 (step S78), and performs a process of deleting the recognition code (step S79). The recognition code is deleted by the recognition code deletion unit 305.

Referring to the operation flowchart of the recognition code distribution server 1 shown in FIG.
Will be described in detail. First, the recognition code distribution server 1 receives a site access from the mobile terminal device 3 (step S81), and distributes the recognition code. Here, of course, in addition to the recognition code, distribution of ordinary search data and the like is also performed. When distributing the recognition code, the telephone number assigned to the sub LCD 43 of the requested portable terminal is used, and for the normal data, the phone number assigned to the main LCD 42 of the requested portable terminal device 3 is used. A call connection is made (steps S82 to S84). This is performed by the recognition code distribution request receiving unit 11 receiving the distribution request and the recognition code distribution unit 12 distributing the recognition code based on the request. Here,
The recognition code is displayed on the sub LCD 43 by the recognition code distribution server 1 making a call connection using the telephone number allocated to the sub LCD 43 separately from the main LCD 42. The requested portable terminal device 3 identifies the header (main screen display inhibition flag attached to the header) and identifies the main LCD.
The display on the display 42 may be prohibited.

Then, the recognition code and the program data are transmitted to the portable terminal device 3 which has made the request (steps S85 and S86), and after the recognition code has been used, the deletion data is transmitted to prompt the deletion of the recognition code. Remove (steps S87, S88). The transmission of the deletion data is performed by the recognition code deletion data transmission unit 13.

As described above, according to the present invention, the user accesses the site to request the download of the recognition code,
When the response is returned, it is displayed on the sub screen instead of the main display screen. For this purpose, for example, the header attached to the recognition code is read and displayed on the main display screen. In this case, different telephone numbers are assigned to the main display screen and the sub-screen, and the recognition code distribution server connects to the sub-screen. Further, the recognition code displayed on the sub-screen is read by a bar code reader, and after executing the defined service, the recognition code is deleted based on the deletion data transmitted from the recognition code distribution server. Further, when a download request is made again after the recognition code is displayed on the sub-screen, the erasure data may be transmitted from the recognition code distribution server to the portable terminal device.

As a result, since the recognition code is received on the sub-screen, unlike the main display screen, it is difficult to transfer the data to a third party or deal with tampering with the contents. This eliminates the problem of bar code reading inconsistency. Regarding sub-screens, since there are few models currently installed, it is easy to standardize specifications, which improves bar code readability.

In the embodiment of the present invention, only an example in which the recognition code is used as a ticket is shown.
D can also be used as a commuter pass, point card,
Application to an electronic wallet is also possible. Although only a mobile phone is shown as the mobile terminal device 3, other mobile terminals such as PDAs can be similarly applied. Further, the mobile phone has been described by taking a two-fold model as an example, but the present invention is not limited to the two-fold model. It goes without saying that the sub-screen may be attached to any part of the mobile phone (portable terminal device). In addition, assuming the open Internet as a communication line, Pointto Point
Needless to say, a two-point direct communication line may be used.
