Access Cards And Biometric Readers
Limiting Entry With Access Cards And Biometric Readers
Access cards and biometric readers both need to work in conjunction with automated door locks or gate and garage door motors. There are basically two types of automated door locks and these are magnetic and electronic. Both work on the same principal that requires a signal to be sent from the scanner for access cards and biometric readers before the lock will be released and the door or gate opened.
While most people are quite au fait with the way access cards work, biometric scanners are more complicated and newer on the market. Both access cards and biometric readers have the same application though and that is to limit access to an entire property or specified restricted areas within a building. Access cards and biometric readers are more commonly used in office, commercial, industrial and other work related environments.
Many of these types of establishments are starting to replace their systems for access cards and replacing them with biometric readers. This is mainly due to the fact that biometric readers are nearly infallible whereas the duplication or unauthorised production of access cards has become relatively easy. Theft of access cards is also possible whereas biometrics cannot be stolen and duplication is difficult and nearly impossible.
There are 3 types of biometric scanners that are being commonly used. The first and most well known of these is a fingerprint scanner that can be attached to an electronic door lock or to a computer to limit access. Iris scanners and hand mapping technology are becoming more and more popular and can be applied in the same way as a fingerprint scanner.
All these biometric readers work in much the same way using an infrared light to read the unique qualities of a fingerprint, iris or entire hand. The biometric readers then access a data base that stores the information regarding the fingerprints, irises or hands of persons authorised to gain entry. If the reader finds the information stored in the databanks, the door lock is released but the door will remain locked for persons who have no authorisation for access.
Probably the best way to ensure that you security measures are optimised is to use access cards and biometric readers in conjunction with one another throughout the work environment.
