Biometric Access Control
Once limited to military use in the most sensitive of locations, biometric security is now inexpensive and a viable security solution for many businesses. Biometric readers are based on reading a unique pattern within the human body, either the fingerprint or the pattern of blood vessels within the eye or hand. This is incredibly secure as these patterns are unique to each individual person. The ideal solution for highly sensitive areas or protecting high-value assets, biometrics entirely remove any security loopholes in access control systems. By individually identifying each and every person people entering and leaving controlled areas based on their individual characteristics you avoid any problems caused by cards and tokens being forgotten, lost, or stolen. You also prevent people clocking each other in or out.
How do biometric readers work?
Biometric readers require that a an accurate image of a specific physical feature of each user entered into the system. This is stored electronically and whenever someone uses a controlled doorway the reader checks the stored image against that presented. The most common biometric reader uses geometric patterns within a fingerprint, but other methods are available using the eyes (specifically the retina or iris), hand and palm vein, face recognition, fingerprint matching, and even voice pattern. Each method has its own benefits. Biometric access control requiring the hand is less convenient where users of the system are likely to not have their hands free for instance.
