Hence in this paper i introduce some combinational techniques of securing the smart card using a biometric algorithm. This algorithm uses fingerprint recognition as a reliable method among biometric feature recognition technology which is widely applied in personal identification for the purposes of high degree of security that can be used to authenticate and secure the transactions using smart card.
