Since every fingerprint is unique, identifying criminals was an easy process, provided it matched with their criminal list of fingerprint database. This similar technology has now further moved forward and is rampantly being used as a fingerprint recognition device which is a biometric device. Fingerprint recognition devices work on some simple principles; firstly storing information of a person’s finger e.g. ridges, loops, branches on a finger.
