SYSTEM FOR DATA FIELD AREA ACQUISITION IN IC CARD FOR MULTIPLE SERVICES ABSTRACT OF THE DISCLOSURE Information indicating the limit of size of area which is permitted to a service provider and an authentication code of the service supplier are stored in an IC card upon issuance. When a service is to be added, a service supplier is authenticated, and thereafter, acquisition of a data field area within a predetermined size of data field area is permitted. Thus, in the IC card for multiple services, upon addition of a new service after card issuance, the use of a remainder vacant area in the IC card by an unauthenticated service supplier and the exclusive use of the vacant area by a specific service supplier are prevented.
