Thermal scanners sense the temperature differences on the contact surface, in between fingerprint ridges and valleys.Īll fingerprint scanners are susceptible to be fooled by a technique that involves photographing fingerprints, processing the photographs using special software, and printing fingerprint replicas using a 3D printer.Ultrasonic fingerprint scanners use high frequency sound waves to penetrate the epidermal (outer) layer of the skin.This type of scanner tends to excel in terms of precision. Capacitive or CMOS scanners use capacitors and thus electrical current to form an image of the fingerprint.Optical scanners take a visual image of the fingerprint using a digital camera.The measure of the fingerprint image quality is in dots per inch (DPI). The basic function of every type of scanner is to obtain an image of a person's fingerprint and find a match for it in its database. ![]() There are four types of fingerprint scanners: optical scanners, capacitance scanners, ultrasonic scanners, and thermal scanners. Because there are countless combinations, fingerprints have become an ideal means of identification. Fingerprints are uniquely detailed, durable over an individual's lifetime, and difficult to alter. Everyone has patterns of friction ridges on their fingers, and it is this pattern that is called the fingerprint.
