Abstract

PURPOSE:To show the arrival of the time of a battery to be exchanged, by issuing an alarm based on the output of the battery incorporated in an IC card when it is lowered less than a prescribed voltage. CONSTITUTION:A CPU5 in an IC card processor 1, when an IC card being inserted, makes a voltage detection circuit 4 detect a voltage supplied through the contact part 2 of an IC card reader/writer. The CPU5 discriminates whether a detected voltage is lowered less than the prescribed voltage, and when it is lowered less than the prescribed voltage, it displays the alarm which represents that it is required to exchange the battery on a display unit 7. In such a way, it is possible to surely recognize the arrival of the time of the battery to be exchanged.
