Fingerprint scanning is the
acquisition and recognition of a person’s fingerprint characteristics
for identification purposes. This allows the recognition of a person
through quantifiable physiological characteristics that verify the
identity of an individual.
There are basically two different types of finger-scanning technology
that make this possible.
One is an optical method, which starts with a visual image of a finger.
The other uses a semiconductor-generated electric field to image a
finger.
There are a range of ways to identify fingerprints. They include
traditional police methods of matching minutiae, straight pattern
matching, moiré fringe patterns and ultrasonic.
