METHODS AND SYSTEMS FOR PERFORMING TOKENLESS FINANCIAL TRANSACTIONS OVER A TRANSACTION NETWORK USING BIOMETRIC DATA

摘要

Systems and methods for performing tokenless financial transactions over a transaction network using biometric data. Financial transactions are completed without tokens, such as credit cards, debit cards, magnetic stripe cards, smart cards, RFID devices, and the like. A customer's identity is authenticated and the transaction is accepted by the customer using biometric information obtained at the point of sale from the customer by means of a point of sale terminal. In preferred embodiments, the customer's biometric information never leaves the point of sale terminal, but, rather, is authenticated over a transaction network in conjunction with a server that holds reference templates of the customer's biometric information, as well as account information. Transactions may be authorized directly by a participating financial institution or indirectly through payment networks such as Visa® and MasterCard®.
