In terms of technological advancement, biometrics is one of the most creative technologies inspired by nature. Biometric identification eliminates the need for tokens such as keys, cards and passwords as well as the vulnerabilities that hinders them. Tokens can be duplicated or decoded, unique biometric characteristics such as face, fingerprint, voice iris and palm pattern on the other hand can not be duplicated or decoded.


Biometric identification utilizes this uniqueness to produce fully automated systems. When combined with computerized monitoring, it is an effective security surveillance and management system.
