Title: BIOMETRIC VERIFICATION SYSTEMS AND METHODS FOR PAYMENT TRANSACTIONS
Abstract:
According to some embodiments, a point of sale device may read a user's biometric information. The point of sale device may then execute an encryption algorithm on the biometric information read to create a token key value. The point of sale device may also receive a personal identification number value from the user and transmit the token key value and the personal identification number value to an authentication server. The authentication server may determine that the received token key value and the personal identification number value match a verified token key value and a verified personal identification number value in a registered user database. The authentication server may then transmit a signal to the point of sale device indicating that the received token key value and the personal identification number value match the verified token key value and the verified personal identification number value in the registered user database.
