ABSTRACT:
An IC card having a plastics card body which mounts a CPU, a RAM, a ROM, a solar battery mounts also to EEPROM (electrically erasable programmable read only memory), which is used for identification of a card owner. Due to high power consumption of said EEPROM, a tandem type solar battery in which a plurality of opto-electric conversion cells are laminated on a substrate is used. The present IC card can operate with only the solar battery mounted inside of the IC card, and has no secondary battery.
