A biometric fingerprint scanner is a biometric device that uses a scanner to scan the fingerprint of an individual and then compares it to a ready database before displaying the result on the unit or on an attached computer. While scanners in the past were heavy and large, the latest scanners are small enough to be incorporated on a mouse, a keyboard or even a laptop. Since fingerprints are unique to each person on earth including twins, such scanners can be used not only as a security tool to allow access to only approved people but also to track their movements while also noting down the time when such authentication might have taken place.
