Title:
SELECTING METHOD FOR IC CARD
Document Type and Number:
Japanese Patent JPH0214340
Kind Code:
A
Abstract:

PURPOSE: To connect a reading device to the IC card of the plural types of storing capacity and to eliminate the designation of a connecting position to the IC card reading device by providing identifying function in the IC card side.

CONSTITUTION: In order to execute reading and writing with a memory card reading device 1, a card selecting signal 5 is outputted and next, an address signal is outputted through an address line 3 to a memory card 3. The memory card inputs the two signals to an identifying information generating part 9 and detects coincidence between an identifying switch 12, which is set from an external part to an arbitrary address, and a specified signal line input Ax+1... of the address signal in a deciding circuit 13. Only in the case of coincident decision, an identifying signal is outputted form an identifying signal line 14. The output of an address decoder 10 can be executed with this output of the identifying signal and a semiconductor storage 11 can execute writing and reading operation to the instruction of the memory card reading device 1.
