Access Control & Identification
With an access control solution, persons or object (e.g. vehicles) are identified and then access is granted. It is very important to choose the right type of identification. The choice partly determines, the operation, security level and usability of the system. Identification can be done on the basis of the following three principles, or a combination thereof:
A keypad on or next to a door is an easy form of access control. Only the person who knows the Personnel Identification Number (PIN), can open the door. This is also a disadvantage; the PIN can be passed. Identification will be more accurate when several types of identification are combined.
Cards or tags are widely used to control access. It is important that you select the right card / tag and the corresponding communication protocol.
Biometric identification systems examine the specific features , s.e. iris or retina, of a person. They are perfect identifiers because they examine features that are absolutely unique. In general, these are a very reliable systems.
