FIG. 5 shows the configuration of the command file after setting personal data for the command file of FIG. Each issued command is composed of a command header 51, a data length 52, and a data 53, which become an INF (information) part of an IC card transmission message to be described later.
[0021]
FIG. 6 shows a format of a transmission message when the INF part of FIG. 5 is transmitted to the IC card. This IC card transmission message is composed of an NAD (node address) unit 61, a PCB (protocol control byte) unit 62, an LEN (length) unit 63, an INF unit 64, and an EDC (epilogue) unit 65. The format is defined in ISO / IEC7816-3 which is an international standard specification.
[0022]
Next, the flow of the IC card issuing process in such a configuration will be described with reference to the flowchart shown in FIG.
When the power of the IC card issuing system is turned on, an issuing system program 31 for controlling the entire system stored in the auxiliary storage device 3 is expanded on the memory 2 of the host computer 1 and then the host computer. The control of 1 is transferred to this program, and the processing by this system is started.
[0023]
First, in step S1, the operator performs a specific operation using the keyboard 5, for example, to open an initial value registration screen on the screen of the display device 4, and on this registration screen, the IC card P1 to be issued will be issued. An initial value written in advance in the memory in the IC chip M1 is registered. The registered initial value is stored, for example, in the memory 2 in the host computer 1 and is referred to as necessary.
[0024]
Next, in step S2, the operator executes input of issuance information such as the name of the issuance data file storing the issuance data of the IC card to be issued from the keyboard 5. These data are expanded in the memory 2 in the host computer 1 and referred to as necessary.
[0025]
Next, in step S3, it is searched whether or not the issue data file corresponding to the issue data file name specified in step S2 exists in the issue data file 33 in the auxiliary storage device 3. Here, if the corresponding issuance data file does not exist in the issuance data file 33, the process proceeds to step S4, and error processing such as displaying an error message on the display device 4 and interrupting or stopping the IC card issuance processing is performed. Execute.
[0026]
On the other hand, if the corresponding issuance data file exists in the issuance data file 33, the process proceeds to step S5, and all the personal ID numbers stored in the personal ID recording unit 12 in the issuance data file specified in step S2 are displayed on the display device 4. Is displayed. Here, the operator uses the keyboard 5 or a mouse (not shown) to select a personal ID number to be issued. In the selection of the personal ID number, one or a plurality of personal ID numbers can be selected and specified at random from all the personal ID numbers displayed on the display device 4.
[0027]
When the selection of the personal ID number by the operator is completed and the issuance start instruction is given from the keyboard 5 by the operator in step S6, the unissued IC card set in advance by the operator by operating the transport unit 25 in step S7. P1 is conveyed from the input unit 22 to the reader / writer device 21.
[0028]
Next, in step S8, by referring to the command management file of FIG. 4 stored in the memory 2 of the host computer 1, personal data to be set in the first command stored in the command file of FIG. Search for and read. Next, in step S9, it is checked whether or not the read personal data is the same as the memory initial value registered in step S1, and if it is not the same as the memory initial value, the INF section shown in FIG. If it is the same as the initial value of the memory (stored in the memory 2), the INF part is not generated (step S12), the process returns to step S8, and the next personal data is read. The same operation as above is repeated.
[0029]
In step S11, it is checked whether or not the setting of personal data has been completed for all commands defined in the command file of FIG. 3. If not, the process returns to step S8 to set personal data for the next command. And repeat the same operation as above.
[0030]
In this manner, when the setting of personal data is completed for all commands defined in the command file of FIG. 3 for a certain individual, the format shown in FIG. 5 is obtained. The example of FIG. 5 corresponds to FIGS. 3 and 4 as described above, but the case where the INF portion is not generated because the personal data with the command ID “04” matches the memory initial value. Show.
[0031]
When the setting of personal data for all commands defined in the command file is completed in step S11, the first INF part in the file of FIG. 5 is used in step S13 as shown in FIG. By generating an IC card transmission message and transmitting it to the unissued IC card P1 via the reader / writer device 21, the personal data in the first INF section is written into the memory in the IC chip M1.
[0032]
Next, in step S14, it is checked whether or not the response message from the unissued IC card P1 indicates a normal end of writing. If it does not indicate a normal end, an issuance error is determined. In steps S15 and S16, an error message is displayed. When the operator clicks a confirmation button (not shown) displayed on the display device 4, the unissued IC card P <b> 1 with an issuance error is conveyed to the reject unit 24, and the process proceeds to step S <b> 18 described later.
[0033]
As a result of the check in step S14, if the response message indicates the normal completion of writing, it is checked in step S17 whether the generation and transmission of the IC card transmission message for all INF units has been completed. As a result of this check, if the generation and transmission of the IC card transmission message for all the INF units is not completed, the process returns to step S13 to generate the IC card transmission message using the next INF unit, and perform the same operation as above. repeat. As a result of the check in step S17, if the generation and transmission of the IC card transmission message for all INF units has been completed, the process proceeds to step S18.
[0034]
In step S18, the unissued IC card P1 in which the issued data is written becomes the issued IC card P2, and is taken out from the reader / writer device 21 by the transport unit 25, transported to the stack unit 23, and proceeds to step S19. In step S19, it is checked whether the issuance data of all the personal ID numbers designated in step S5 has been written. If not, the process proceeds to step S20, and the next personal ID number is made current. Return to S7.
[0035]
The above processing is repeated for the number of designated personal ID numbers until the IC card issuance is completed. Then, when the IC card issuance processing is completed for the number of designated personal ID numbers, in step S21, as the issuance record table, the issuance date, the name of the issuance data file, the issued personal ID number, the total number of issued cards Alternatively, the normal / abnormal issue number of sheets is output by the printer 6 and the series of IC card issuance processing ends.
[0036]
As described above, according to the above-described embodiment, when the initial value of the memory in the IC card is registered in advance, when writing the personal data into the memory, it is equivalent to the initial value of the memory in the personal data. It is possible to reduce the number of commands to be issued by determining whether or not there is data, and if there is data equivalent to the memory initial value, control is performed so that the data is not written to the memory. Thereby, useless IC card transmission messages can be reduced, writing of personal data to the memory can be minimized, and the issuing time can be shortened.
[0037]
In the embodiment, by registering an initial value written in advance in the memory in the IC card, when writing personal data into the memory, the personal data is equivalent to the memory initial value. Although the case where control is performed so that the writing of the data is not performed when data is present has been described, the present invention is not limited to this, and for example, writing into the memory in the IC card is performed based on the same idea. By registering unnecessary write-unnecessary data in advance, when writing personal data to the memory, if there is data equivalent to write-unnecessary data in the personal data, do not write the data You may make it control.
[0038]
【The invention's effect】
As described above in detail, according to the present invention, it is possible to provide an IC card issuing system capable of minimizing writing of issued data to the memory and shortening the issuing time.
