Abstract

A method for validating an electronic payment by a credit/debit card in a transaction system. The method includes registering a purchase of an article by a buyer using a credit/debit card associated with at least one PIN code, checking that the at least one PIN code is associated with the number of said credit/debit card provided by said buyer to said seller terminal, checking, by said electronic payment center, whether or not said at least one PIN code is valid, and one of: after the at least one PIN code is found to be valid, checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party; after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting that the third party validate the purchase; and after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting said at least one PIN code from the third party. The third party is a prime owner of the credit/debit card.

Claims

1. A method for validating an electronic payment by a credit/debit card in a transaction system, comprising:

registering a purchase of at least one article by a buyer using a credit/debit card associated with at least one PIN code at a seller terminal connected to an electronic payment center by a communication network;

checking, by the electronic payment center, that the at least one PIN code which is provided by said buyer to said electronic payment center is associated with the number of said credit/debit card provided by said buyer to said seller terminal;

checking, by said electronic payment center, whether or not said at least one PIN code is valid; and

one of;

after the at least one PIN code is found to be valid, checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party;

after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting that the third party validate the purchase, and

after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting said at least one PIN code from the third party,

wherein the third party is a prime owner of the credit/debit card.

2. The method according to claim 1, wherein said buyer has a terminal which is connected to the communication network and said terminal is configured to transmit the number of the credit/debit card.

3. The method according to claim 1, wherein the credit/debit card number and the at least one PIN code which have been provided to said seller terminal by said buyer are transmitted to said electronic payment center to check whether the at least one PIN code is associated with said credit/debit card number.

4. The method according to claim 3, wherein said electronic payment center checks in at least one profile table whether said PIN code is associated with the credit/debit card number.

5. A system for validating an electronic payment by a credit/debit card comprising means adapted for carrying out the steps of the method according to claim 1.

6. The method of claim 1, wherein each PIN code of the at least one PIN code is used only once and a different PIN code of the at least one PIN code is used for a later transaction.

7. The method of claim 1, wherein the at least one PIN code is associated with two or more members of a group and the group is associated with the number of the credit/debit card.

8. The method of claim 7, wherein the at least one PIN code is different for different members of the group, and wherein the at least one PIN code authorizes a different purchasing amount for the different members of the group.

9. The method of claim 7, wherein the third party is a member of the group and the third party limits a transaction involving the credit/debit card to a pre-determined purchasing amount.

10. The method of claim 1, wherein the third party is a living human being and wherein the method comprises not contacting the third party but instead checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from the third party.

11. A method for validating an electronic payment by a credit/debit card in a transaction system, comprising:

registering a purchase of at least one article by a buyer using a credit/debit card associated with at least one PIN code at a seller terminal connected to an electronic payment center by a communication network;

checking, by the electronic payment center, that the at least one PIN code which is provided by said buyer to said electronic payment center is associated with the number of said credit/debit card provided by said buyer to said seller terminal;

checking, by said electronic payment center, whether or not said at least one PIN code is valid; and

after the at least one PIN code is found to be valid, one of;

checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party; and

contacting a third party via a communication network and requesting that the third party validate the purchase,

wherein the third party is a prime owner of the credit/debit card.

12. A system for validating an electronic payment by a credit/debit card comprising means adapted for carrying out the steps of the method according to claim 11.

13. The method according to claim 11, wherein each PIN code of the at least one PIN code is used only once and a different PIN code of the at least one PIN code is used for a later transaction.

14. The method according to claim 11, wherein the at least one PIN code is associated with two or more members of a group and the group is associated with the number of the credit/debit card.

15. A method for validating an electronic payment by a credit/debit card in a transaction system, comprising:

registering a purchase of an article by a buyer using a credit/debit card associated with at least one PIN code at a seller terminal connected to an electronic payment center by a communication network, checking, by the electronic payment center, that the at least one PIN code provided by said buyer is associated with a number of said credit/debit card provided by said buyer to said seller terminal;

checking, by said electronic payment center, whether or not said at least one PIN code is valid; and

after the at least one PIN code is found to be valid, one of;

checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party; and

contacting a third party via a communication network and requesting that the third party validate the purchase,

wherein the third party is a prime owner of the credit/debit card.

16. The method according to claim 15, further comprising transmitting, with the seller terminal, the number of the credit/debit card.

17. The method according to claim 15, further comprising checking, by the electronic payment center, whether the at least one PIN code is associated with the credit/debit card number in at least one profile table.

18. A system for validating an electronic payment by a credit/debit card comprising means adapted for carrying out the steps of the method according to claim 15.

19. The method according to claim 15, wherein each PIN code of the at least one PIN code is used only once and a different PIN code of the at least one PIN code is used for a later transaction.

20. The method according to claim 15, wherein the at least one PIN code is associated with two or more members of a group and the group is associated with the number of the credit/debit card.
