Explanation:
A biometric device is used for uniquely recognizing humans based upon one or more intrinsic,
physical, or behavioral traits. Biometrics is used as a form of identity access management and access
control. It is also used to identify individuals in groups that are under surveillance.
Biometric characteristics can be divided into two main classes:

1.Physiological: These devices are related to the shape of the body. These are not limited to the
fingerprint, face recognition, DNA, hand and palm geometry, and iris recognition, which has largely
replaced the retina and odor/scent.
2.Behavioral: These are related to the behavior of a person. They are not limited to the typing
rhythm, gait, and voice.
