In payment card applications, using biometrics is of primary interest because it makes the cardholder verification method (CVM) simpler with a higher level of security. Instead of personal identification numbers (PINs) or signatures, individual and unique physical information is applied in the payment procedure. Among several biometric alternatives, the use of fingerprint recognition is becoming the most popular method in plastic smart card applications, because of user convenience and compatibility with the current payment infrastructure without modifications or additional devices [1]. Nevertheless, several challenges should be overcome for a payment method using
