METHOD AND SYSTEM TO PREVENT FRAUD IN PAYMENT SYSTEMS TRANSITIONING TO MOBILE PAYMENT AND CHIP CARDS

摘要

A payment system for reducing fraud is payment card transactions. The system includes a payment device coupled through a merchant to a payment network and a fraud prevention system coupling an issuing bank to the payment network. The fraud prevention system includes a transaction processing module and a monitor/detect module. The transaction processing module receives transaction messages from the payment network and sends transaction messages to the payment network from the issuing bank and provides transaction processing to approve or reject transactions. The monitor/detect module is coupled between the transaction module and a database module storing payment method data. The monitor/detect module compares established payment precedent of parties to a transaction to detect fraud and sends feedback to the transaction processing module.
