Abstract

PURPOSE:To extend the life of a battery of a terminal equipment of an IC card which is driven by the battery and is portable, by distinguishing between a clock which operates the IC card and a clock which operates a microcomputer in the terminal equipment of the IC card. CONSTITUTION:The terminal equipment consists of a read/write part 2, a clock 3 for an IC card 1, a microcomputer 4 which controls the read/write part 2, a clock for the microcomputer 4, and the driving battery. That is, the clock which operates the IC card and the clock which operates the microcomputer in the terminal equipment of the IC card are distinguished to operate the microcomputer in the terminal equipment of the IC card at a low speed, and therefore, the life of the battery of the terminal equipment of the IC card which is driven by the battery and is portable is extended.
