The principle of the safes with fingerprint recognition.

Fingerprints are the uneven lines on the skin at the end of the finger, although fingerprints are only a small part of the human skin, it contains a lot of information.

These lines are different in the pattern, breakpoints, and intersections, in information processing they are called “features”, medical has proved that these features are different for each finger, and these features have uniqueness and permanence.

Therefore, we can match a person with his fingerprint features and verify his true identity by comparing them with pre-saved fingerprint features.

Automatic Fingerprint Identification System (AFIS) through special photoelectric conversion equipment and computer image processing technology, can collect, analyze and compare a person’s fingerprints, thus automatically, quickly, and accurately identifying individuals.
