ABSTRACT:
In a multi-application IC card system which is loaded with a plurality of applications and is provided with a platform allowing deletion of the applications, the platform (1) contains an AID control table for controlling the correspondence between each application and its application identifier (AID), and the change of each AID is conducted by rewriting the corresponding AID in the AID control table. Alternatively, the platform (1) has a function of applying an alias AID in addition to the application identifier (AID) assigned to each application and controls the correspondence among each application, its AID, and its alias AID by using an AID control table.
