PAYMENT PROCESSING SYSTEM TRUSTED AGENT IDENTIFICATION

摘要

Compliance with data security requirements is determined for an agent that processes transactions for merchants. An authorization request received from the agent for a transaction on an account that includes a bank identification number (BIN) licensed to an acquirer and an agent unique account result (AUAR) for the agent. The AUAR is valid when a primary account number (PAN) corresponding to the account and an agent identifier can be derived from the AUAR. The AUAR is invalid when the PAN lacks such correspondence or when the agent identifier lacks uniqueness among other agent identifiers. The acquirer receives the identify of the agent and the BIN when the AUAR is invalid, when the agent isn't registered to use the BIN, and when the agent identifier is invalid. When the agent is not registered to use the BIN, the acquirer will be informed.
