In the IC card 11, the arithmetic processing unit 13 of the IC card processes the received signal to update the data in the read / write memory unit 16. The read data is similarly input to the display device 69 via the IC card read / write unit 8, but is further sent to the personal computer 23 via the IC card read / write unit 9.

In this way, by using the display device as an IC card reader / writer,
Reading of balance data in the IC card, reading of transaction history information, and the like can be performed using a personal computer. In the above description, data is exchanged with a personal computer via the IC card read / write unit 9 of the display device 69. However, as shown in FIG. 3, the personal computer and data are transmitted using the communication driver unit 6 and the external terminal 46 of the display device. It is also possible to exchange

Next, a method for displaying an application name on the display unit when the user selects an installed application will be described.

FIG. 11 is a diagram showing a list of applications displayed on the display device 1 of the present embodiment. FIG. 11 shows only one example, but here, for example,
Application A relates to an electronic money card, application B relates to a credit card, application C relates to a point card, and application D relates to an airline mileage card. Here, in order to display each application data, a card application program stored in the IC card and a device application program stored in the display device 1 are required. In FIG. The name of the program is shown.

First, the data structure in the IC card will be described with reference to FIG. The IC card is standardized by ISO7816, and the Master file (
Hereinafter, referred to as MF), Directory file (hereinafter referred to as DIR file), Answer To Reset file (hereinafter referred to as ATR file), Dedicated file (hereinafter referred to as DF), Elemental
It is composed of five types of files, y files (hereinafter referred to as EF).

When a clock signal and a reset signal are supplied after powering on the IC card, I
The C card is activated, and various applications in the IC card can be used. Then, immediately after the activation of the IC card, the MF 51 in FIG. 12 is selected.

When the IC card is activated, an answer to the IC card is received from the IC card.
Although a t signal (hereinafter referred to as ATR) is returned to the display device 1, the additional data that could not be stored is limited in FIG.
Stored in the ATR file 53. Furthermore, the card application list information stored in the IC card is stored in the DIR file 52 for each record number. Each card application shown in the DIR file is stored in the DFs 54 to 56 in FIG. 12, but the unique data related to each application can be stored and used in the EFs 57 to 59 in FIG. is there.

The record number starts from 1 and increases every time another application is written to the IC card. Thus, for example, when three types of applications are stored in the IC card, the record number is 1,
2 and 3.

When the user selects the desired application, first of all ISO7
The DIR file is selected using the Select File command defined in 816, and the MF is moved from the MF to the DIR file in the IC card. Similarly, the DIR is set by the Read DIR Record command defined in ISO7816.
Application I stored in the IC card by looking at the list information in the file
D (hereinafter referred to as AID) is read. With this AID, the device application program can determine the name of the card application. If a desired application is stored, the AID of each application read by the DIR file is set in the Select File command, and the DIR file is moved to the DF of an arbitrary application. Then, each application program is operated to display application data.

The AID is an alphanumeric ID number of up to 16 characters, and is determined for each application as shown in an example corresponding to FIG. The device application identifies the read AID, determines the name of the application, and causes the display unit to display the name of the application.

Next, the application name display method according to the present embodiment will be specifically described with reference to FIG. Here, as shown in FIG. 14, for example, the card application programs A, B, and D are stored in the IC card, and the device application programs AA, BB, and CC are stored in the display device. To do. In FIG. 12, it is assumed that applications A, B, and D are stored in DFs 54, 55, and 56, respectively.

In this case, the following (1) to (4) are conceivable as a method for displaying the application name on the display unit 3 of the display device 1.

First, (1) is a case where the names of applications that match between the card application and the device application are displayed. In this example, application A and application B are displayed. In the case of FIG. 14, since the cursor line displayed in black and white inversion is at the position of application A, application A is selected and executed when the user presses the enter key in this state. on the other hand,
When the user moves the cursor line to the position of application B by operating the scroll key, application B is selected by pressing the enter key,
And executed.

Next, (2) is a case where the name of the application stored in the display device is displayed. In this case, the application A and the application B can be similarly selected by the user, but the card application program related to the application C is an IC card. The user cannot select this application to display the data because it is not stored inside.

Next, (3) is a case where the name of the application stored in the IC card is displayed. In this case, the application A and the application B can be selected by the user, but the device application program related to the application D is displayed in the display device. Similarly, since it is not stored, the user cannot select this application to display data.

Finally, (4) is a case where all the names of applications stored in the IC card or the display device are displayed. In this case, the user cannot select application C and application D.

As described above, in order to display the application data on the display device 1,
It is necessary to store related application programs in the IC card and the display device. In the case of (1), all the applications shown on the display unit can be selected by the user, but on the other hand, there is an application (in this case, application D) that is not displayed despite being stored in the IC card. It is expected that it will be confused without being able to choose. This is a scene that is sufficiently assumed when the user uses another person's display device. In the case of (2), the same thing can occur.

In the case of (2), even if the user selects the application C, data cannot be displayed because there is no related card application in the IC card. Therefore, in order to distinguish between an application that can be displayed and an application that cannot be displayed, for example, an asterisk may be displayed next to an application name that cannot be displayed (in this case, application C).

On the other hand, in the case of (3), for the applications A and B, the device application program can display the name of the application by determining the AID. However, since there is no device application program for application D, the display device cannot determine the name of application D from the read AID.

In the above case, instead of displaying the name of application D, the read AID (in this case, ABCD444444444444) can be displayed as it is. However, since the user cannot identify an application only with this AID, it is inconvenient.

Therefore, as shown in FIG. 15, an application list information storage unit 49 is provided in the display device 1, and a correspondence table as shown in FIG. 13 is stored in the application list information storage unit 49. By identifying the AID read from, it is possible to determine and display the name of the application even when there is no device application program. In this case, the application list information storage unit 49 records the correspondence (correspondence table) of all the applications that can be used at that time, and the application list information management unit 50 of the terminal 29 in the service center periodically records it. By downloading and constantly updating to the latest data, even when new application data is registered in the IC card, it can be handled. Connection to the modem is possible by using an external terminal of the display device, but as shown in FIG. 25, it can also be made via an IC card read / write unit of the display device. The application list information storage unit 49 can be stored in the IC card.

FIG. 16 is a diagram illustrating an example of a processing flow when the application name is determined and displayed using the above-described AID. When the user turns on the power of the display device 1 and inserts the IC card into the display device (301, 302), the display device sends a Select File command and moves from the MF to the DIR file (303). In DIR file, first set record number 1 (
304), and a Read DIR Record command is transmitted (305). Thereafter, the display device receives the response from the IC card (306), and if the response is received normally, the AID in the DIR file relating to the record number 1
Is read (307).

If the device application program can identify the AID (308), the application name is displayed on the display unit 3 (310).
If the AID cannot be identified (308), the data in the application list information storage unit 49 in the display device is read (309), the name of the application is determined, and the application name is displayed on the display unit 3 (310). .

Thereafter, the record number is incremented by 1 (311), and the same processing is performed. In addition,
If an error is returned when the Read DIR Record command is sent (
306) Since there is no more card application in the IC card, the processing relating to the display of the application name is terminated (312).

The case where the name of the application is determined using the AID has been described above.
In addition to the method described above, the application name can be recognized by directly recording the application name in the IC card. In this case, by recording in a common format in a common area in the IC card,
All application names in the IC card can be read by a unified method.

For example, by recording each application name with an ASCII code in the above-mentioned DIR file or ATR file, the display device can easily read all application names in the IC card. In addition, the Sel
Select any application with the ect File command and select DIR file
It is also possible to record the application name in the response signal from the IC card when moving from e to an arbitrary DF. Further, each application name can be recorded in the ATR.

Here, an example in which an application name is stored in the DIR file will be described with reference to FIG. Rea shown in FIG.
When the d DIR Record command is sent, the IC card sends Read DIR Record response data of length 2 bytes shown in (b) of FIG. 17 to the display device, and then shows whether the response data is normal or abnormal in FIG. The status information (Status) of (c) is sent out 2 bytes. This command and response data is standardized by ISO7816, and x1 contains DIR file.
Enter the record number of the application you want to read in e.

Here, the structure of the response data is also standardized by ISO7816. Information (Tag) for identifying data is 1 byte, followed by information (Length) indicating the record data length is 1 byte, and further is Length. A structure composed of three pieces of information of the indicated record data information (Records) (hereinafter referred to as T
(Referred to as LV configuration).

The response data for each application starts with a tag that begins with “61”, and then the value obtained by subtracting 2 bytes from the response data length (x2 bytes) is Length.
indicated by th. Thereafter, the AID is indicated by a tag “4F”. Here, in order to store more detailed information of the application, other information may be stored in the TLV configuration.

Thereafter, the application name is stored in the DIR file. Here, for example, it is assumed that the application name is stored in a TLV configuration having a head of “50”. In this case, for example, by storing the application name in ASCII code and displaying the character information of the ASCII code as it is on the display device, various application names can be read out in a unified manner.

In the above description, the application name is stored in the DIR file, but it is also possible to store the application name in the ATR file based on the same concept. In this case, data is acquired using the Read Binary command and response defined in ISO7816.

As described above, by recording in a common area in the IC card in a common format, the display device can read the application name of the IC card in a unified manner, so that the device application program is stored in the display device. Even if there is not, at least only the application name in the IC card can be displayed.

In this case as well, since the user cannot select the application, as described above, for example, it is desirable to display the asterisk separately from other selectable applications by displaying it next to the application name. .

The display method when displaying the application name on the display device 1 has been described above. Finally, the display order when displaying a plurality of applications will be described. In the case where a plurality of application names are displayed on the display unit 3, for example, the following can be considered as a display method.

  (1) Display in the order of record numbers in the IC card.

(2) Display in the order of memory addresses where device applications are stored in the display device.

(3) Display the application names in alphabetical order or in order.

  (4) Display the application usage frequency in order.

  (5) Display the applications in order of installation date.

(6) The user sets the display order.
In the case of (4) above, as shown in FIG. 18, for example, an application usage count storage unit 60 is provided in the display device 1, and the usage count of each application is counted each time the user selects an application. Then, when displaying the list of application names, for example, the application names are displayed in descending order. Similarly, the cases (5) and (6) can be easily realized by providing a storage unit for storing the date of installation or a storage unit for storing user setting values in the display device. In the above description, the storage unit is provided in the display device. However, the storage unit may be provided in the IC card.

The name of the application in the above embodiment does not necessarily need to be a formal name, and it is sufficient that the user has sufficient information to recognize the application. Therefore, information other than character information such as an application abbreviation and graphic information representing the application is treated as an application name as described above. For example, in an application named XYZ Camera Point, without displaying the formal name XYZ Camera Point on the display device, XYZ,
Even if abbreviations such as XYZ cameras and XYZ points are displayed, the user can fully
It can be recognized that the application is a Z camera point. Further, the number of display characters may be limited depending on the size of the display unit of the display device. Also in this case, it is useful to display abbreviations such as XYZ power. In addition to displaying characters, the user can recognize the application by displaying graphic information such as a camera or graphic information such as a logo mark.

As described above, in the embodiment shown in FIG. 1 to FIG. 25, the connection between the IC card and the IC card read / write unit has been described with respect to the contact type IC card that exchanges signals by the contact point. The same connection can be made in the system to be used. For example, the connection may be made using RFID or the like. Further, in the embodiments of the present specification, an IC card is taken as an example, but the shape is not necessarily limited to a card shape, and a thick shape, a rod shape, or other shapes may be used as the IC of the present specification. It can be used like a card.

1 to 25, the application related to the money amount information such as electronic money and points has been described. For example, schedule management, health / health card, membership card or game may be performed as an application. it can.

Here, when application data is newly added to the IC card, the data added to the IC card cannot be viewed on the same display device unless the display control device application program is added to the display device.

Therefore, in the present invention, the device application program can be easily added by installing the device application program from a personal computer or modem via a communication driver such as RS-232C. When new application data is added, it can be easily handled, improving versatility and convenience.

Further, in the present invention, the device application program can be similarly installed and exchanged with a personal computer through the contact of the IC card. In this case, a special external terminal or communication driver is provided on the display device side. This is unnecessary, and the cost of the display device can be further reduced.

Furthermore, when the user selects an application, the type of application data in the IC card may not match the type of device application program in the display device. is necessary. Therefore, in the present invention, when displaying only the name of the application whose type matches the application in the IC card and the device application on the display device, or displaying all the names of the application in the IC card or the device application, It is made possible to make it selectable, which increases convenience for the user.

When displaying all the names of applications in the IC card, it is impossible to determine the name of the application by identifying the AID read from the IC card for data for which there is no device application program in the display device. Therefore, in the present invention, a name list is stored in advance in a display device or an IC card for all applications that are widely used in the world.
Even if there is no device application program, A read from the IC card
It is also possible to identify the ID information and display the application name, which is also convenient in this respect.

Furthermore, in the present invention, as another method, by storing the application name in the common format in the common area in the IC card, the application name can be displayed at any time in the same manner, which is similarly convenient. It will be a thing.
In this case, it is possible to store the ASCII character code in the DIR file, for example.
