Abstract

Abstract An IC card system allows a correct access by a right terminal to a specifically designated memory area of an IC card (1). Depending upon the terminal to which the IC card (1) is applied, the IC card performs identification and selection of the right area to be connected with the terminal. The IC card with a number of thus-featured areas enables a card holder to use it for many different terminals.
