Abstract: A memory region on an IC card has a hierarchical structure. Each application allocated on the memory region is registered in a directory, and the memory region is managed in directory units. A personal identification code is set for each application and directory, and the access right is controlled in application units or directory units. If a mobile terminal is lost, the right to access each application in the IC card automatically disappears. Therefore, the right to access each application allocated to the memory region on the IC card is efficiently controlled.

Abstract: An electronic money system terminates communication to a management center indistinguishably from a case in which the communication to the management center is completed within a predetermined period when it is impossible to complete the communication to the management center within the predetermined period. By switching an operation mode, a predetermined portable terminal is used instead of a communication line to upload and download data. When it is impossible to obtain data required for processing through the communication line, processing is performed based on data possessed up until that time.
