How are biometrics helpful?

Answer 1

Biometrics are helpful tools for security and identity verification. They are especially useful to establish the identity where a person might be stranger to the other, for example huge databases like banks. Biometrics identify on the basis of features unique to an individual, like signature, finger print, iris etc. These are difficult to forge. Biometrics used in home doors do not require carrying a key, or the fear of the key getting stolen. Biometrics are also used to identify criminals and determine their identity.

Answer 2

Biometrics are helpful as they provide a secure method for identifying individuals based on unique biological traits such as fingerprints, facial features, or iris patterns. This technology is difficult to forge or steal, increasing security in applications like access control or device authentication. Biometrics also offer convenience by eliminating the need for passwords or tokens, enhancing user experience.
