PURPOSE:To reduce time and labor when plural transactions are performed by an automatic transaction device by providing a storage part which stores the data of plural transaction contents at a transaction medium. CONSTITUTION:The system is comprised of an LSI in which the contact part 62 of IC memory 66 as a storage element, an input/output control part 67, a central control part 68, and the storage part 69 are integrated with high density, and the storage part 69 is comprised of a program memory 69a which stores a control procedure, programmable data memory 69b, and key data memory 69c protected so as to prohibit read/write from the outside of a card. In such a way, the data of plural accounts are stored in the data memory of the IC card. Thereby, it is possible to select the data from the plural accounts stored in the IC card at every transaction in one time of transaction. |
