The advantages and disadvantages of fingerprint lock

What is the principle of fingerprint lock? The principle of fingerprint lock technology refers to the uneven lines on the front skin at the end of the finger. Although the fingerprint is only a small part of the human skin, it contains a lot of information. These lines are different at the pattern breakpoints and intersections. In the information processing, they are called 'features'. It has been proved in medicine that these features are suitable for each hand They are all different, and these features are rare and permanent. What are the good aspects of fingerprint lock for people? It has been proved in medicine that these characteristics are different for each finger, and these characteristics are rare and permanent. Therefore, we can match a person with his fingerprint, and verify his real identity by comparing his fingerprint characteristics with the pre saved fingerprint characteristics. Therefore, the above characteristics of fingerprint become the super important evidence for identification and are widely used in the field of public security criminal investigation and justice. Fingerprint lock is an intelligent lock, which is the crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint has been widely used in the field of public security criminal investigation and judicature because it has become a super important evidence for identification. Fingerprint authentication is convenient, fast and accurate. So fingerprint locks are becoming more and more common in families. What is the advantage of fingerprint lock? The security of fingerprint lock should be judged according to the recognition ability of fingerprint lock. The recognition ability of fingerprint lock mainly depends on the algorithm accuracy of its built-in recognition software. 95% of the existing production units can not solve the problem, mainly through outsourcing. Powerful manufacturers have the ability to design and develop locks by themselves. Therefore, the lock body is the core component that truly reflects the technical level of the manufacturer, and it is also the core technology of the whole fingerprint lock. What are the disadvantages of fingerprint lock? The use of LCD can definitely make fingerprint lock more intelligent and user operation easier, which is obvious. It's like a mobile phone. The screen is black. You can still make a phone call. It's just inconvenient. The configuration of liquid crystal is not a simple material accumulation, but also involves the reasonable design of software and circuit system. Generally speaking, using this technology is just like fingerprint lock itself replacing mechanical lock, which is the inevitable development of technology and market! So is fingerprint lock worth buying? Fingerprint sensors are mainly optical sensors and semiconductor sensors. Optical sensors mainly refer to the use of optical sensors such as coms to obtain fingerprint images, which are generally made into integral modules on the market. Such sensors are relatively low in price, but large in volume, generally used in fingerprint locks, fingerprint access control and other products.
