Abstract

PURPOSE:To enable connecting a single card to the external devices of plural different characteristics by providing a means for converting to a cipher capable of being mutually inputted and outputted between plural different signal connecting mechanisms and a CPU. CONSTITUTION:The signal connecting mechanisms 2-5 of different char acteristics are disposed on the front and the back of a plastic card 1 and select ed according to the inserting direction of the card. A signal switching machine 8 outputs a selecting signal 10 to the CPU so as to decide a selected connecting mechanism by a CPU 7. Namely, the card 1 selects one signal connecting mechanism according to a direction for inserting to the external device and the selecting signal 10 is outputted to the CPU 7 by a power source supplied from the selected signal selecting mechanism. The CPU 7 decides a specified interface from a program interface with the plural external devices existing on a memory 6 according to this information to exchange data with the external device by the use of the interface.
