Smart card access control has become a big question for almost all enterprises. Nowadays many enterprises use logical smart card access control, or in other words two factor authentications. For an enterprise, smart card access control works in two ways, card ID and biometrics. In a physical control access a PIN is only enabled. A PIN only reveals that a person knows a secret whereas biometrics can prove that the individual is true and unique from others.
Smart card access control can control logical and physical access simultaneously. Smart card access control enables the same credentials for both the cases of opening a door and accessing a computer system.
