Enables running of programs in IC. In the memory area 1902 in the IC card, an application program (AP) for online business, the telephone number of the partner host at the time of online service, the identification information of the AP in the partner host, the node of itself and the partner (host, terminal, etc.) Store the address.

In the program area 1903 of the MPU in the card,
As a basic program, an AP communication processing program, a terminal communication processing program, a terminal and a host communication processing program are stored. In the IC card terminal 1910, communication processing programs 1911 and 1912 for the paired card and the host exist respectively, but no application program exists. The IC card terminal is provided with a keyboard 1913.
The remote host 1920 has a terminal and card communication processing program 1921 and an application program.
1922 is stored.

[0005] With such a system configuration, an online job is executed in the following procedure. That is, after inserting the IC card 1901 into the IC card terminal 1910, the card holder inputs a desired application name or service name from the keyboard 1913. The card-to-card communication processing program 1911 transmits this information to the program area 1903 in the card. The basic program of 1903 in the program area is
The application program (AP) is started while referring to the memory management table in the memory area 1902, and the execution right of the business process is given. The AP first causes the IC card terminal 1910 to establish a communication link with the partner host via the basic program. Then, the AP information in the host is transmitted to the partner host 1920 via the basic program of the card, the IC card terminal 1910, and the line 1930, and the application program is transmitted.
Start 1922. Subsequent business processing is basically performed by the AP in the memory area 1902 in the card and the AP 1922 in the partner host 1920.
It is performed by end-to-end communication between them.

At this time, the basic program in the memory area 1902 in the card, the card / host communication processing programs 1911 and 1912 in the IC card terminal 1910, and the communication processing program 1921 in the partner host 1920 are end nodes as intermediate nodes. Support end communication. Each end node and intermediate node has its own node address, and knows the partner node address. All information transferred between the nodes has a format as shown in FIG. 20, and describes an information transmitting node address and an information receiving node address. This ensures that the intermediate node transmits the information to the legitimate receiving node.

As is apparent from the above description, if this system is used, no application program is required in the IC card terminal 1910. The card owner can receive an online service with the desired partner host 1920 or another IC card terminal 1910 by storing in the card 1901 an application program that can execute the service desired by the card owner.
