Description

Lock with fingerprint identification function

Technical Field

The invention relates to the technical field of fingerprint identification, in particular to a lockset with fingerprint identification.

Background

Traditional mechanical locks are easily unlocked by techniques. The traditional password combination lock has the advantages that the password is too simple, the password combination is less, and the lock can be opened after a certain number of times of trial unlocking. The safety is not high. If a key is lost or a password is forgotten, the traditional lockset can not be unlocked. The fingerprint identification is adopted, and a key and a password are not required, so that the use is convenient. The unlocking of the lock is controlled by adopting a fingerprint identification technology, the characteristic that the fingerprint of a person has uniqueness is utilized, the safety of the lock is enhanced, and the defect that the traditional key lock is easily unlocked by the technology is overcome. The defect that the password of the traditional password combination lock is too simple is avoided. The fingerprint identification is adopted without a key and a code. Is convenient to use. The safety is good. At present, a gun lock adopts a mechanical and simple password combination mode, so that the gun lock is inconvenient to use, and the gun lock cannot be unlocked due to the fact that a key is lost or a password is forgotten.
