The use of biometric technologies within physical access control systems is one of the most broadly commercialized sectors of biometrics, outside of forensic applications. A key issue for the successful integration of biometrics within a physical access control system is the interface between the biometric and the access control infrastructures. For this reason, the biometric system must be designed to interface appropriately with a wide range of access control systems. Also, the usability demands of a physical access control system are significant as, typically, all users need to be enrolled for subsequent successful usage more or less on a daily basis. The most significantly-deployed biometric types for access control are: fingerprint; hand geometry; face and iris.
