Card holder-type balance display

A card holder (1) provides a balance display (20) for an IC card (80) utilized for a system for settling cash utilizing the IC card. A balance display is provided with the card holder-type body (10) having a card slot provided in the body. A liquid-crystal display and at least one push-button (30) are arranged on the body for user interface. A cover member (40) is attached to the body via a hinge (50) so that it can be opened or closed. When an IC card is inserted into the body and the push-button is pressed, the liquid-crystal display is lit and the current balance of currency is displayed on the liquid-crystal display. When the cover member is opened and the IC card is extracted, the display of the balance is switched to a blinking display. When a settlement is performed using the IC card, a microcomputer in the body can operate to displace the balance after the settlement as well as a paid or received amount, in addition to the previous balance before the settlement.
