What are some facts about fingerprint access control?


Quick Answer

Biometric readers are different depending on the design and the technology used to manufacture them. No biometric scanners are equal, as each variation is specifically designed for a different function. Common biometric scanners include face, hand geometry, iris and finger scans, states ExplainThatStuff.

The most popular scanner is the optical finger due to its durability, and it is user friendly. There are different variations of biometric algorithms. Highly efficient algorithms provide accurate search results at shorter periods, recounts Humanity.

Biometric technology is not fit for every industry. For instance, in the case of a builder who handles blocks every day, the system may deny the builder access after some period, says Humanity.

This is because once a finger is introduced into the system, the system stores a master file, and each time the builder transacts, the system compares both images. Since the nature of the builder’s work is to lay bricks, most probably, the physical characteristics of the finger may change, hence the denied access alert, points out ExplainThatStuff.

Generally, the biometric system access location requires the fingerprint scanner to be away from direct sunlight or extreme industrial lighting, a flat and level floor surface, enough elbow room to make the transaction comfortable and natural for users, and the reader must be mounted about 1.5 meters above the floor, says Humanity.
