Hand geometry recognition is used heavily for which access control?

• A. PC access
• B. door access
• C. watch list access
• D. server access

Answer: (B)

Hand geometry recognition measures the size and shape of the hand—finger lengths, widths, and palm dimensions—to verify identity. This biometric is well suited for physical entry because it works quickly at a doorway, is comfortable for users, and doesn’t rely on fingerprints or iris patterns that can be worn down or damaged. In access control, the goal is to grant or deny entry to a building or room, so a hand-geometry reader is typically paired with a door controller to unlock the door for authorized personnel. It’s not commonly used for computer or server access, which usually require credentials or more highly distinctive biometrics for remote or high-security authentication. “Watch list” access isn’t a standard method of granting entry. For these reasons, hand geometry is used heavily for door access.
