FIG. 3 shows a processing flow in this case. The flowchart on the left side of FIG. 3 shows the flow of processing on the IC card terminal side, and the flowchart on the right side shows the flow of processing in the IC card. First, in step 301,
The process is started by starting the first program in the IC card terminal. For example, in the case of the above-mentioned cooperation between the prepaid card function and the point card function, this corresponds to activating the prepaid card function. Next, step 3
At 02, the first processing in the IC card terminal, in the example described above, the processing of the prepaid card function is executed. Here, a command is transmitted from the IC card terminal to the IC card in order to activate a corresponding program in the IC card. As a result, in step 307, the IC
The execution of the prepaid card function program or the like in the card starts. Thereafter, until the prepaid card function is completed, step 302 of the IC card terminal side processing and IC
Step 307 of the card-side processing transfers the command and the response. The transfer technology of the command and the response between the IC card terminal and the IC card is based on the interface defined in the ISO7816 series which is an international standard. The command is a message transmitted from the IC card terminal to the IC card.
It has the data configuration of (a). 201 includes information indicating the type of command content, for example, a data read instruction, a data write instruction, and the like. 202 is a parameter accompanying the command. On the other hand, the response is I
This is a message sent from the C card to the IC card terminal.
It has the data configuration shown in FIG. Reference numeral 204 includes processing result information indicating the success or failure of the processing requested by the command. An output result 203 of the process requested by the command includes, for example, data read in response to the data read command.

[0006] In the first processing, in the above-described example, following the end of the processing of the prepaid card function, in step 303, the point card function to be linked is activated. This step 303 is performed by an input operation such as menu selection by the operator. As a result, a point card function or the like to be linked in step 304 is executed.
Also in this case, the corresponding point card function program in the IC card is activated by the command. After that,
As before, by transferring commands and responses,
Point card processing such as addition of points in the IC card is executed. Thereafter, the start operation of the program to be linked (Step 305), the execution of the program to be linked (Step 306), and the execution of the corresponding program in the IC card (Step 309) are repeated by the number of functions to be linked.

As described above, in order to link a plurality of functions, it is necessary for the operator to sequentially start desired programs.

On the other hand, Japanese Patent Application Laid-Open No. 7-37147 discloses a "card processing apparatus with an interlocking processing function" in which a technique for automatically starting a program to be linked is presented. According to this technology, since the processing of the point processing function is automatically started after the processing of the prepaid card function, the labor of the operator can be reduced, the operation error can be prevented, and the required operation as a whole can be prevented. Time can be reduced.
