Building access controls include security devices such as entry key cards and fobs, entry key locks and pads, and biometric techniques such as fingerprint, face, and voice recognition. Biometric access control systems use special scanners or devices, as well as building access control software that includes recognition algorithms and databases. Other types of access control, security and biometrics equipment are commonly available.
