ABSTRACT:
The data for setting the operating conditions of an IC card is transferred from the IC card to the card terminal, and stored in it. The IC card is driven by the stored data. A signal for checking a state of the compatibility of the IC card with the card terminal is exchanged with each other between the IC card and the card terminal, thereby checking the compatibility between them.
