What is a fingerprint lock

Fingerprint refers to the uneven lines on the frontal skin of the fingertip. Although the fingerprint is only a small part of the human skin, it contains a lot of information. These lines are different in patterns, breakpoints, and intersections. We call them "characteristics." Medically these characteristics have been proved to be different for each finger, and these features are unique and permanent, so we can associate a person with his fingerprint and compare His fingerprint features and pre-saved fingerprint features can verify his true identity. Therefore, the above features of fingerprints have become the most important evidence for identification and are widely used in public security criminal investigation and judicial fields. Fingerprint authentication is convenient, fast, and accurate.

We are no stranger to fingerprint locks, and many televisions have played it. The safest place is a fingerprint lock when entering the door. And it is understood that the fingerprint lock is currently the most secure lock.

Fingerprint lock is a kind of intelligent lock with human fingerprint as the carrier and means of identification. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint locks generally consist of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replicability of the fingerprint determines that the fingerprint lock is the safest kind of lock among all current locks. In addition to fingerprint identification, fingerprint locks, according to national regulations, should be equipped with emergency mechanical keys. The product quality specification is based on the “General Public Safety Industry Standard for Fingerprint Anti-Theft Locks (GA701-2007)” of the Public Safety of the People's Republic of China.

Each person's fingerprint is different, each person's finger fingerprint is not the same, the world has not yet found two identical fingerprints. This ensures the uniqueness of the fingerprint. Fingerprint lock security is also guaranteed.

The English name of the fingerprint lock is Fingerprint Lock.

The core function of fingerprint lock is nothing but fingerprint opening and fingerprint management. There are a lot of manufacturers in their products integrated doorbell, voice prompts, networking, telephone alarms and other 20 kinds of functions. At first glance, the user has a lot of functions, so it seems that other unnecessary expenses can be saved and it may be tempting. Personally think that this is an irresponsible design of the manufacturer. The main function of the fingerprint lock is security and convenience. In addition to the door lock function, the fingerprint lock generally has function of adding, deleting, and clearing fingerprints. The high-performance fingerprint lock is also equipped with a human-machine dialogue system such as a liquid crystal display screen, which has a high level of intelligence, relatively convenient operation, and operation guidance. Query usage records and built-in parameters, setting status and other functions.

Fingerprint management generally implements hierarchical management. Administrators have all the functions such as opening the door, adding fingerprints, deleting fingerprints, emptying fingerprints, querying usage records, setting system parameters, etc., while ordinary users only have door opening functions.
