1. An apparatus for processing a transaction, comprising:
- an electronic processor programmed to execute a set of instructions which, when executed by the processor, cause the apparatus to process the transaction by;
receiving, from a point of sale terminal, an authorization request message for the transaction comprising an account identifier that identifies an account used to conduct the transaction, the account identifier not including information identifying a first issuer for the account, and an issuer identifier data string separate from the account identifier that identifies the first issuer for the account, wherein the account identifier is extracted, by the point of sale terminal, from a first data field of a payment device associated with the account that does not store the issuer identifier data string, and wherein the issuer identifier data string is extracted, by the point of sale terminal, from a second separate data field of the payment device, after the payment device interacts with the point of sale terminal;
determining the first issuer for the account based on the issuer identifier data string;
routing the authorization request message to the first issuer using the issuer identifier data string;
receiving from the first issuer for the account an authorization response message containing a decision from the first issuer whether to approve or deny the transaction; and
forwarding the authorization response message to the point of sale terminal, wherein the account used to conduct the transaction is later identified with a second issuer different from the first issuer and used to conduct a second transaction.

Abstract
A system, apparatus, and method for providing and using a payment account or payment device identifier when conducting a transaction. The bank identification number (BIN) is decoupled from the primary account number (PAN) or other form of device identifier when generating the payment account or payment device identifier. The payment account or payment device identifier is used to access information regarding the issuer, with that information being used to route a transaction authorization request message to the appropriate entity.

4. A method for processing a transaction, comprising:
-
receiving, by a server computer from a point of sale terminal, an authorization request message for the transaction comprising an account identifier that identifies an account used to conduct the transaction, the account identifier not including information identifying a first issuer for the account, and an issuer identifier data string separate from the account identifier that identifies the first issuer for the account, wherein the account identifier is extracted, by the point of sale terminal, from a first data field of a payment device associated with the account that does not store the issuer identifier data string, and wherein the issuer identifier data string is extracted, by the point of sale terminal, from a second separate data field of the payment device, after the payment device interacts with the point of sale terminal; determining, by the server computer, based on the issuer identifier data, the first issuer for the account; routing, by the server computer, the authorization request message to the first issuer using the issuer identifier data string; receiving, by the server computer, from the first issuer for the account, an authorization response message containing a decision from the issuer whether to approve or deny the transaction; and forwarding the authorization response message to the point of sale terminal, wherein the account used to conduct the transaction is later identified with a second issuer different from the first issuer and used to conduct a second transaction. - View Dependent Claims (12, 13, 14)
