Identification is the technology that makes it possible to identify someone by their fingerprints. The person has to place his/her finger on the optical reader and the result will be the display of the person’s name. Verification is the technology that compares someone’s fingerprint with the fingerprint of whoever this person claims to be. Because of that, this method requires also a password or an access card. The Identification technology compares (in an efficient way) the requested fingerprint with all the recorded fingerprints in the system. The Verification technology compares the person’s fingerprint with the already recorded fingerprint of this person. That is why the technologies are also called 1:N (one X all) and 1:1 (one X one).
