Abstract

PURPOSE:To prevent an illegal access by applying discriminating information to respective areas obtained by dividing a data memory part in the same card correspondingly to various types of systems, recognizing the applied system and making access only to the corresponding data area. CONSTITUTION:An IC card has a data memory 3 formed into blocks every applied system and the respective blocks A, B, C have respectively the discriminating information 4. The recognition of the relevant system is performed by a collating means 21, according thereto, the data area made access is controlled. Namely, an applied operation system 'A' makes access to an area set in the system 'A' and in this case, other area set in the same card cannot be made access. In this manner, the respective applied systems can be made access without considering the other systems and an illegal access such as a destruction or the like of the data by the other system can be prevented.
