Access Control/Time & Attendant Systems

Access Control/Time & Attendant Systems

The goal of any access control system is to let authorized people, not just their credentials, into specific places. Only with the use of a biometric device can this goal be achieved.

A card-based access system will control the access of authorized pieces of plastic, but not who is in possession of the card. Systems using PINs require an individual only know a specific number to gain entry; but who actually entered the code cannot be determined. On the contrary, biometric devices verify who people are by what they are, whether by hand, eye, fingerprint, or voice recognition.

User-friendliness is a key aspect of a successful implementation. The process should be quick and easy, such as having a picture taken by a video camera or touching a fingerprint scanner. The advantage biometric authentication provides is the ability to require more instances of authentication in such a quick and easy manner that users are not bothered by the additional requirements.
