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.

Claims

1. A card verification system comprising:

a card in which a card identification code is registered;

a read unit configured to read said card identification code from said card; and

a verification apparatus configured to verify said card only when a place in which said read unit is located, corresponds 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 place, and searches and acquires said 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 having another table which shows a correspondence relation between said card identification code and said mobile phone, and

said area being 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 acquiring 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 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 a place in which said read unit is located corresponds to said card identification code, said method comprising:

acquiring from said read unit the place of said read unit which read said card;

acquiring an identification code of said card;

determining whether or not said place of said read unit corresponds to said identification code;

when said place of said read unit does not correspond to said identification code, prohibiting settlement.

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

deleting said area; and

when a second area of the card is not a recognized area, prohibiting the settlement.

9. A card verification method comprising:

registering an identification code area comprising an area where a card is located and an identification code of the card;

transmitting over a telecommunication network the identification code area to a verification module, upon request by the verification module;

reading the card identification code from a card by a read unit; and

verifying the card only when a location of the read unit corresponds to the identification code area.

10. A method of claim 9, wherein the identification code area is coincident with an area for one or more cells belonging to a mobile telephone, and

wherein a verification apparatus accesses a table that shows a correspondence relation between the card identification code and the mobile telephone.

11. A card verification system, comprising:

a position registering module configured to register a geographical place and an identification code of a card;

a verification module configured to receive over a telecommunication network the place and the identification code of the card from said position registering module, and further configured to verify the card read by a card reader requesting card verification only if a location of the card reader corresponds to the identification code of the card.

12. The card verification system according to claim 11, further comprising a mobile phone, and a table showing a correspondence between the identification code of the card and said mobile phone, wherein the area of the card is coincident with an area for one or more cells to which said mobile phone belongs.

13. The card verification system according to claim 11, wherein the card is a credit card.
