Methods of processing transactions and related systems and computer program products

A method of operating a merchant node, the method comprising:

• receiving payment information for a transaction from a user device, wherein the payment information comprises an identification for a credit/debit account and a name on the credit/debit account, wherein the identification is different than a complete account number for the credit/debit account, wherein the payment information is received by a processor of the merchant node through a network interface of the merchant node from the user device;
• responsive to receiving the payment information, transmitting transaction information for the transaction from the merchant node to an authentication node, wherein the transaction information comprises the identification for the credit/debit account, the name on the credit/debit account, a transaction identification for the transaction, and a transaction amount, and wherein the transaction information is transmitted by the processor of the merchant node through the network interface to the authentication node, wherein the identification for the credit/debit account that is transmitted to the authentication node comprises a portion of the complete account number for the credit/debit account and wherein the identification for the credit/debit account that is transmitted to the authentication node omits another portion of the complete account number;
• after transmitting the transaction information to the authentication node, receiving an authorization result for the transaction from an acquirer node, wherein the authorization result includes the transaction identification for the transaction, wherein the authorization result is received by the processor through the network interface from the acquirer node;
• and
• responsive to receiving the authorization result, processing by the processor the transaction, wherein processing the transaction comprises completing the transaction responsive to the authorization result from the acquirer node being positive.

A computer system comprising:

• a processor;
• a network interface coupled to the processor;
• and
• a memory coupled to the processor and comprising computer readable program code that when executed by the processor causes the processor to perform operations comprising:
• receiving transaction information for a transaction from a merchant node through the network interface, wherein the transaction information comprises an identification for a credit/debit account, a name on the credit/debit account, a transaction identification for the transaction, and a transaction amount for the transaction;
• transmitting a confirmation request through the network interface to a user device associated with the credit/debit account responsive to receiving the transaction information;
• receiving a positive confirmation response through the network interface from the user device associated with the credit/debit account, wherein the positive confirmation response corresponds to the confirmation request;
• determining a complete account number for the credit/debit account using the identification for the credit/debit account and the name on the credit/debit account responsive to receiving the transaction information, wherein the identification for the credit/debit account is different than the complete account number for the credit/debit account, wherein the identification for the credit/debit account that is received from the merchant node comprises a portion of the complete account number for the credit/debit account and wherein the identification for the credit/debit account that is received from the merchant node omits another portion of the complete account number;
• and
• transmitting account information through the network interface to an acquirer node responsive to receiving the positive confirmation response from the user device associated with the credit/debit account, wherein the account information comprises the complete account number for the credit/debit account, the name on the credit/debit account, the transaction identification, and the transaction amount, and wherein the account information is transmitted by the processor through the network interface to the acquirer node.

A computer program product comprising:

• a non-transitory computer readable storage medium having computer readable program code embodied in the computer readable storage medium that when executed by a processor of a computer system causes the computer system to perform operations comprising:
• receiving transaction information for a transaction from a merchant node, wherein the transaction information comprises an identification for a credit/debit account, a name on the credit/debit account, a transaction identification for the transaction, and a transaction amount for the transaction, wherein the transaction information is received by the processor through a network interface from the merchant node;
• transmitting a confirmation request through the network interface to a user device associated with the credit/debit account responsive to receiving the transaction information;
• receiving a positive confirmation response through the network interface from the user device associated with the credit/debit account, wherein the positive confirmation response corresponds to the confirmation request;
• determining a complete account number for the credit/debit account using the identification for the credit/debit account and the name on the credit/debit account responsive to receiving the transaction information, wherein the identification for the credit/debit account is different than the complete account number for the credit/debit account wherein the identification for the credit/debit account that is received from the merchant node comprises a portion of the complete account number for the credit/debit account and wherein the identification for the credit/debit account that is received from the merchant node omits another portion of the complete account number;
• and
• transmitting account information through the network interface to an acquirer node responsive to receiving the positive confirmation response from the user device associated with the credit/debit account, wherein the account information comprises the complete account number for the credit/debit account, the name on the credit/debit account, the transaction identification for the transaction, and the transaction amount, and wherein the account information is transmitted by the processor through the network interface to the acquirer node.
