Biometrics
Biometrics is the technique of studying the physical characteristics of a person such as your fingerprint, hand geometry, eye structure or voice pattern.
Biometric methods of identification work by measuring unique human characteristics as a way to provide irrefutable proof of identity, for example, iris or finger scanning or dynamic signature verification.
For the effective "two-factor" security authorisation of an individual to a time and attendance system, dermal fingerprint recognition is used in conjunction with a smart card.
