Biometrics is a physical property recognition system that identifies and verifies specific physical characteristics of an individual. The characteristics used in biometrics range from fingerprints to voice recognition and retinal patterns, to name but a few. Biometrics has developed to an advanced level and is now widely used in the workplace, campuses, government buildings, and even at airports. With biometrics data is collected at the enrolment stage and then matching is done every time a person gets to a specific terminal. It is also possible to use biometrics simply to track who enters without using it as access control or limitation system. It uses a one to one authentication system and a one to many identification process. Fingerprint is perhaps the most common and most accepted form of biometrics used today.
