The CCD makes use of photosites that are sensitive to light. Optical scanners use a CCD or charge couple device much like the ones used in camcorders and digital cameras. The basic function of these two types of scanners is to get an accurate image of an individual's fingerprint and find a match for this print in the database. There are two types of fingerprint scanners, the optical scanner and the capacitance scanner. As such, fingerprints have become an ideal means of identification.
Because there are countless combinations between these two sets of factors, a person's fingerprint is unique. The person's fingerprint is determined by his or her genetic makeup and other factors in his or her mother's womb. These marks have a pattern and this pattern is called the fingerprint. These marks on the fingers are mainly for gripping things as they provide frictional resistance. Biology of a FingerprintĮvery person has marks on his fingers. Fingerprint scanners are now being used in police stations, security-intensive industries and, most recently, on computer shops as a peripheral device for computers. Fingerprint scanners are biometric security systems designed to use the distinct features of an individual's fingerprints to provide security.
