There are many different ways in which biometric technology allows for biometric authentication. Almost any part of the body can be used to identify a specific individual.

Biometric technology can also identify individuals based off of finger or hand geometry, gait, odor, vein pattern and voice. Secondary aspects of biometric authentication focus on an individual's writing, specifically the signature. All of this technology is particularly helpful in terms of police work and overall security.
