IC CARD

摘要

PURPOSE:To reduce the memory capacity of a terminal by storing and managing the guidance information of application names, the guidance information of service names and scenario information in/by an IC card itself. CONSTITUTION:A memory 6 in an IC card 4 is logically divided into a common data field (CDF) and three applification data fields (ADF) ADF1-ADF3. A guidance information record 10 indicating application names is stored in the CDF. An intra-memory address information record 11 of ADFs corresponding to respective application is also stored in the CDF. A record 13 recording service names and scenarios corresponding to respective service is stored in the ADF1. A reference program for reading out the information records 10, 13 from the IC card 4 and a reference program 5 for informing the application and service to the IC card 4 are stored in the memory 3 of a control part 1.
