Multi-point authentication for payment transactions
View Patent ↗Authentication includes receiving an indication of physical possession of a payment card by a merchant and receiving a purchase request for an authorization of an exchange from the payment account of the cardholder to the merchant. Authentication includes assigning a randomized transaction identifier to the request for the authorization of the exchange. The method also includes transmitting the request for the authorization of the exchange from the payment account of the cardholder to the merchant and receiving the assigned randomized transaction identifier and a randomized authentication identifier associated with the randomized transaction identifier from a payment association, the payment association determining whether the request for the authorization of the exchange is valid. Authentication includes transmitting a copy of the randomized authentication identifier to the mobile device and receiving validation that the transmitted copy of the randomized authentication identifier from the mobile device matches the randomized authentication identifier.
1. A system for use with a host payment association server that is configured to validate transactions of a payment account and communicate with a linked mobile device that is configured to validate payment transactions, comprising:
one or more computer processor circuits that are configured to host a transaction validation application that is configured to:
receive, by a point-of-sale (POS) terminal, a first indication that a payment account of a cardholder is associated with a mobile device of the cardholder;
receive, by the POS terminal, after receiving the first indication, a second indication of physical possession of a payment card by a merchant;
receive, by the POS terminal, a purchase request for an authorization of an exchange of funds from the payment account of the cardholder to the merchant;
assign, by the POS terminal, a randomized transaction identifier to the request for the authorization of the exchange of funds;
transmit, by the POS terminal, the request for the authorization of the exchange of funds from the payment account of the cardholder to the merchant;
receive, by the POS terminal, the assigned randomized transaction identifier and a randomized authentication identifier associated with the randomized transaction identifier from a payment association, the payment association determining whether the request for the authorization of the exchange of funds is valid;
transmit, by the POS terminal, a copy of the randomized authentication identifier to the mobile device; and
receive, by the POS terminal, validation that the copy of the randomized authentication identifier transmitted to the mobile device from the POS terminal matches the randomized authentication identifier.
2. The system of claim 1 , wherein the POS terminal is a physical POS terminal.
3. The system of claim 1 , wherein the POS terminal is a computer-based POS terminal.
4. The system of claim 1 , wherein the transaction validation application is configured to transmit, by the POS terminal, a copy of the randomized authentication identifier through the mobile device, visually.
5. The system of claim 1 , wherein the transaction validation application is configured to transmit, by the POS terminal, a copy of the randomized authentication identifier through the mobile device, aurally.
6. The system of claim 1 , wherein the mobile device includes a mobile device application, wherein the mobile device application is configured to communicate with the payment association and the payment account of the cardholder.
7. A computer program product comprising a computer readable storage device having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:
receive, by a point-of-sale (POS) terminal, a first indication that a payment account of a cardholder is associated with a mobile device of the cardholder;
receive, by the POS terminal, after receiving the first indication, a second indication of physical possession of a payment card by a merchant;
receive, by the POS terminal, a purchase request for an authorization of an exchange of funds from the payment account of the cardholder to the merchant;
assign, by the POS terminal, a randomized transaction identifier to the request for the authorization of the exchange of funds;
transmit, by the POS terminal, the request for the authorization of the exchange of funds from the payment account of the cardholder to the merchant;
receive, by the POS terminal, the assigned randomized transaction identifier and a randomized authentication identifier associated with the randomized transaction identifier from a payment association, the payment association determining whether the request for the authorization of the exchange of funds is valid;
transmit, by the POS terminal, a copy of the randomized authentication identifier to the mobile device; and
receive, by the POS terminal, validation that the copy of the randomized authentication identifier transmitted to the mobile device from the POS terminal matches the randomized authentication identifier.
8. The computer program product of claim 7 , wherein the computer readable program further causes the computing device to:
transmit, by the POS terminal, a copy of the randomized authentication identifier through the mobile device, by a wireless transmission.
9. The computer program product of claim 7 , wherein the computer readable program further causes the computing device to:
transmit, by the POS terminal, a copy of the randomized authentication identifier through the mobile device, visually.
10. The computer program product of claim 7 , wherein the computer readable program further causes the computing device to:
transmit, by the POS terminal, a copy of the randomized authentication identifier through the mobile device, aurally.
