Access control, security and biometrics equipment is used to monitor and restrict access to equipment, parts of buildings, or entire facilities. 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.
Access control, security and biometrics equipment limits access to specific personnel and may also monitor their activity while in restricted areas. A building access control system may consist of requiring employees to show identification (ID) cards when entering and exiting a building, signing in and out, or using an access card to automatically gain entrance. Access cards and keypads used in building access controls are types of human interface devices (HID), peripheral devices that have been developed to enable people to interact with a computer or computerized system. A building access control card is the most basic form of access control, security and biometrics equipment in a restricted facility, and may also provide some tracking information such as indicating what time someone gained access to a room. Access card control HID is an emerging technology.

More sophisticated access control, security and biometrics equipment includes biometric technologies, such as retinal scans, voice recognition techniques, and fingerprint verification. Fingerprint biometrics use the statistical phenomenon that no two people have the exact same fingerprint to create secure devices and protocols for building access control. Fingerprint scanners use either optical scanning or capacitance scanning to gather individual fingerprint data. Once the image is recorded, a special algorithm compares the image with one saved in the database. Biometric building access controls can be used to compare all kinds of biological characteristics, including the patterns of people’s retinas and irises in the eye, facial patterns, and hand measurements. Other types of access control, security and biometrics equipment may provide specialized features.
