Abstract

A card verification system is composed of a card 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.

Claims

1. A card verification system comprising:

a card in which a card identification code is registered;

a read unit which reads said card identification code from said card; and

a verification apparatus which verifies said card only when an existing place of said read unit is within an area corresponding to said card identification code.

2. The card verification system according to claim 1, wherein said read unit has a read unit identification code, and notifies said read unit identification code to said verification apparatus, and

said verification apparatus has a table which shows a correspondence relation between said read unit identification code and said existing place, and searches and acquires said existing place corresponding to said notified read unit identification code from said table.

3. The card verification system according to claim 2, further comprising a mobile phone,

said verification apparatus has another table which shows a correspondence relation between said card identification code and said mobile phone, and

said area is coincident with an area for one or more cells to which said mobile phone belongs.

4. The card verification system according to claim 3, further comprising a storage unit which stores data showing said area corresponding to said mobile phone, and

said verification apparatus acquires said area data from said storage unit.

5. The card verification system according to claim 4, wherein a user of said mobile phone deletes said area data from said storage unit by operating said mobile phone, and

said verification apparatus does not verify said card when said area data is not stored in said storage unit.

6. The card verification system according to claim 1, wherein said card is a credit card.

7. A card verification method using a card verification system which comprises a card that a card identification code is registered, a read unit which reads said card identification code from said card, and a verification apparatus which verifies said card only when an existing place of said read unit belonging to corresponds to said card identification code, said method comprising the steps of:

acquiring from said card, an existing place of said read unit which read said card;

acquiring said area from said recorder;

determining whether or not said existing place is in said area;

when said existing place does not belong to said area, prohibiting settlement.

8. The card verification method according to claim 7, further comprising the steps of:

deleting said recorded area; and
