ABSTRACT:
In a processing system for enabling data communication between a card reader/writer and an IC card, the card reader/writer transmits a reset signal to the IC card. When IC card receives the reset signal, a control element initiates operations to execute a self diagnosis program stored in a program memory. When the control element determines according to the self diagnosis that the IC card can be operated normally, the control element reads out initial response data from the program memory and sends it to the card reader/writer. Upon reception of the initial response data, the card reader/writer begins a predetermined operation. If the control element determines that the IC card cannot be operated normally, it inhibits transmission of the initial response data to the card reader/writer and sets the IC card in a halt state.
