Patent abstract
A card verification system in which a card identification code is registered. A read unit reads the card identification code from the card. A verification apparatus verifies the card only when an existing place of the read unit belongs to an area corresponding to the card identification code. The card is a card used for settlement, and is used when the card identification code is read by the read unit. The use place of the card is coincident with the existing place of the read unit. By adding the use place of the card to a verification condition of the card, unjust use of the card can be prevented.
