Fingerprint scanners - Access Control Products

A fingerprint reader or scanner is a type of electronic security system that uses fingerprints for biometric authentication to grant a user access to information or to approve transactions. It used to be that fingerprint scanners are mostly used in access control and time and attendance devices.
Biometrics are unique physical characteristics, such as fingerprints, that can be used for automated recognition. ... This system, called the Automated Biometric Identification System or IDENT, is operated and maintained by OBIM.

Fingerprint scanners work by capturing the pattern of ridges and valleys on a finger. ... As a finger rests on the touch-capacitive surface, the device measures the charge; ridges exhibit a change in capacitance, while valleys produce practically no change at all. The sensor uses all this data to accurately map out prints.
Fingerprint scanners are security systems of biometrics. They are used in police stations, security industries, smartphones, and other mobile devices

The main purpose of biometrics in these applications is to determine or verify someone's identity in order to prevent unauthorized people from accessing protected resources.
