What are Fingerprint Scanners?
Fingerprint scanners are security systems of biometrics. They are now used in police stations, security industries and most recently, on computers.
Every person has marks on his or hers fingers. They can not be removed or changed. These marks have a pattern and this pattern is called the fingerprint. Every fingerprint is special, and different from any other in the world. Because there are countless combinations, fingerprints have become an ideal means of identification.
There are two types of fingerprint scanners: the optical scanner and the capacitance scanner. The basic function of these two types of scanners is to get an image of a person’s fingerprint and find a match for this print in the database. The capacitance scanner is better, because the images are more exact and precise.
