Abstract

A Globally Unique IDentifier (GUID) is used to match an authorization request with an authorization response for a transaction between a merchant and a consumer upon an account within a payment processing system where the payment amount is unknown until after the merchant receives the authorization response that includes the GUID. After receiving the authorization response and when the payment amount is known, the merchant forms a transmission that has information for delivery to an issuer of the account. This information is sufficient for the issuer to forward the payment amount from the account to pay the merchant for the transaction. While including the GUID and the payment amount, the information does not include an identifier of the account.

Claims

1. In a payment processing system that includes a transaction handler module processing a plurality of transactions each characterized by a merchant and a consumer engaging in the transaction for a good or a service upon an account that an issuer has issued to the consumer, wherein the merchant submits the transaction to an acquirer for processing by the transaction handler who requests the issuer to obtain payment for the transaction from the account, and wherein the issuer forwards the payment to the transaction handler who forwards the payment to the acquirer to pay the merchant for the transaction, for each said transaction, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to execute a computer implemented method comprising:

receiving an authorization request having;

a preliminary quantity of funds to be authorized by the issuer;

a code for the transaction that is unique among a plurality of said transactions of one said merchant; and

an account identifier of the account;

associating, with the transaction, a Globally Unique IDentifier (“

GUID”

) that is unique within the payment processing system such that the GUID associated with the transaction is unique among multiple said GUIDs each associated with one said transaction among multiple said transactions of multiple said merchants;

using an algorithm to derive a plurality of said GUIDs, each associated with a corresponding respective said transaction, wherein each said GUID of the plurality of said GUIDs is derived without having a corresponding said account identifier of the account as an input to the algorithm;

forming a first transmission having information for delivery to the issuer and usable to form an authorization response responding to the authorization request, wherein the information includes the GUID;

receiving the authorization response of the issuer, wherein the authorization response includes the GUID but does not include the account identifier;

associating the authorization response with the authorization request by, at least, matching the GUID associated with the transaction with the GUID received in the authorization response;

6. The computer implemented method as defined in claim 1, further comprising forming a fifth transmission includes the GUID and a request to refund the final quantity of funds from the merchant back to the account.

7. The computer implemented method as defined in claim 1, further comprising receiving a fifth transmission addressed to a sponsor of a loyalty program and including the GUID and a request that the sponsor transfer money equal to a value of an incentive given to the consumer whose said transaction satisfies a criterion of the loyalty program.

8. The computer implemented method as defined in claim 1, wherein the preliminary quantity of funds to be authorized is selected from the group consisting of:

a value matching the final quantity of funds;

a nominal value to test whether the account is valid within the payment processing system; and

an estimate of the final quantity of funds, wherein the estimate is determined by the merchant.

9. The computer implemented method as defined in claim 1, wherein the account is selected from the group consisting of:

a credit account;

a prepaid account;

a debit account;

a line of credit account;

a deposit account;

a loan account;

a flexible spending account; and

a health savings account.

22. The computer implemented method as defined in claim 1, wherein the algorithm used to derive the GUID includes having a merchant identifier, parameter of the transaction, geographical indicator of the merchant, random or sequential identifier, or combinations thereof, as an input to the algorithm.

24. The computer implemented method as defined in claim 1 wherein the third transmission includes a remittance request from the merchant.

10. Any payment processing system, comprising a computer usable medium having a computer readable program code embodied therein, in which a merchant and a consumer engage in a transaction, a payment quantity of the transaction being unknown when the transaction is authorized by an authorization, the authorization being received by the merchant from an issuer as being payable upon an account issued to the consumer by the issuer, the account being associated with an account identifier, wherein the merchant submits the payment amount of the transaction to the payment processing system with a Globally Unique IDentifier (“

GUID”

) that identifies;

the transaction from other said transactions within the payment processing system; and

neither the account nor its associated account identifier.

11. The payment processing system as defined in claim 10, wherein the merchant is selected from the group consisting of:

a hotel operator;

a motor vehicle gasoline provider;
