Abstract

Abstract 57 A card (10) contains an IC chip having a CPU (20), a memory (24), etc. When the card (10) is inserted into a terminal device, it is connected to a host computer. Under this condition, the data in the memory (24) of the IC card is processed by the host computer. The memory (24) is manufactured in such a way that the memory area is segmented into a plurality of zones. An access controller (22) for the memory (24) is provided in the IC chip. In issuing the card (10), the access condition of each zone (for example, an assortment of access people and/or a type of access terminal) is programmed into the access controller (22) by a card issuer.
