Abstract
An IC card system according to this invention adopts a so-called intelligent-type IC card which has an internal power source of its own, can store designation data using the power source, and can display the storage content on a display unit. When the IC card is inserted in a terminal, the presence/absence of designation data is judged from the ON/OFF state of the power source of the card and, thereafter, a predetermined processing operation corresponding to the designation data is executed.
