Biometrics

The process of recognizing a human being using one or more inherent physical traits. For example, one may identify a criminal using his/her fingerprints. Biometric products are used for a variety of government and commercial purposes, often for security.

Increasingly popular building security system technology that relies on automated identification of physical characteristics such as fingerprints or retinal scans in order to determine access rights.The technology and the cost have both reached the point that consumer-level biometric security devices are available,such as for use in self-storage facilities and residences.Access codes, keys, and electronic cards are becoming outdated. Developers should bear this in mind when designing new construction and spend a minor amount of extra money necessary for wiring to accommodate biometric systems.
