SYSTEMS AND METHODS TO DETECT CHANGES IN MERCHANT IDENTIFICATION INFORMATION

摘要

A system and method to detect changes in transaction parameters for the identification of a store of the merchant in a payment processing network. The system is configured to monitor input data, such as acquirer's merchant master file (AMMF), transaction records, to detect transaction parameters of a processing entity that partially match with the transaction parameters associated with an external, persistent identifier of the merchant and/or the store of the merchant, determine a change or difference introduced in the detect transaction parameters, and update the set of transaction parameters associated with the persistent identifier of the store of the merchant that can be used to identify the set of transaction parameters of the store in a communication external to the communication system of the payment processing network.

1. A method, comprising:
storing transaction records in a computing apparatus coupled with an electronic payment transaction processing network, each of the transaction records including data fields identifying merchants and transaction terminals of the merchants; storing, by the computing apparatus, identification data, the identification data associating:
an identifier uniquely identify a store of a merchant, andalternative expressions of merchant attributes obtained from the data fields of transaction records of the store of the merchant, the alternative expressions of the merchant attributes identifying one or more transaction terminals disposed in the store of the merchant; determining, by the computing apparatus, a partial match between:
the alternative expressions of the merchant attributes associated with the identifier, andfirst merchant data received within the electronic payment transaction processing network; identifying, by the computing apparatus, a mismatched merchant attribute according to the partial match; and updating, by the computing apparatus, the identification data according to the mismatched merchant attribute.
