ABSTRACT:
An IC card (6) comprises a read only memory (ROM) (2) in which data specifying a financial body and a stored program for processing procedures are stored, a writable and readable random access memory (RAM) (3), and a central processing unit (CPU) (1) for writing or reading out the data and/or program. When, in a transaction processing, a customer inserts his IC card (6) into a terminal (16), the terminal (16) first reads out the financial body specifying data from the ROM 2. If the data as read out is correct, the terminal (16) further generates a signal indicating that the required transaction is possible and provides the signal to the CPU 1 in the IC card, where the stored program for processing procedures is read out from the ROM 2. A transaction is performed in accordance with the read program. If and when no stored program is stored in the ROM 2, the terminal (16) indicates an impossible transaction through a CRT (19) to inform a customer of the fact. The ROM (2) may store a plurality of stored programs for transaction processing procedures, in which case a customer has to select a desired program through an operation of a keyboard (20) in the terminal (16). If and when a version number of the read stored program does not coincide with a version number of the terminal (16), the program is executed after the version number of the read stored program is renewed.
