How much do you know about the fingerprint head of the electronic fingerprint lock? -Media reports

Nowadays, most of the smart door locks on the market will be equipped with a fingerprint opening method, so today I will come to a small science to popularize the knowledge of smart locks about fingerprint heads. Regarding the choice of fingerprint heads, there are currently two mainstream fingerprint heads on the market, one is an optical fingerprint head and the other is a semiconductor fingerprint head. The optical fingerprint head first talks about optics. The principle of optics is similar to taking a picture of fingerprints and then comparing them based on the fingerprints in the database. The advantage of optics is durability, the disadvantages are obvious, the recognition rate is poor, many old people, children, shallow fingerprints, fingerprint failure, will make you very annoying, and finally you can only use other opening methods to open the door lock. In addition, there is a more potential risk. Nowadays, except for a few fingerprint lock companies in China that use their own solutions or truly advanced algorithms, the others are full sets of fingerprint lock solutions made by small companies. A fingerprint lock of poor quality can be easily opened by directly using a fake fingerprint film. Although your own fingerprint film will not be easily obtained by others, this potential risk cannot be ignored. As for the so-called biometric recognition that optics also have, if someone takes your fingerprint film to identify, isn't it a biometric? Generally speaking, in this case, most of the fingerprint locks below 1,000 yuan are directly passed, but it does not rule out some manufacturers who are engaged in price wars and need to be carefully identified. Semiconductor fingerprint head Let's come back to the semiconductor fingerprint head. Relatively speaking, semiconductors will be safer and the recognition efficiency will be better. In addition, some semiconductor identifiers have radio frequency penetration function, and some have self-learning functions. These costs are higher, and the price of corresponding locks will be higher. . The semiconductor fingerprint head has an inevitable problem. Compared with optics, it is very fragile and does not have abrasion resistance. After basically one year, it will gradually appear due to wear and tear, reducing the recognition efficiency and slowing down the response speed. This is true for many small brands and even low-end locks of some big brands. In normal use, the life of the door lock depends on your care. For some better locks, a protective layer will be made on the semiconductor, so that the wear resistance will be much better. In order to protect the fingerprint head and make the door lock more durable and longer service life, Fuyu's semiconductor fingerprint heads are all made with a protective layer, which can be used with confidence. Then, when choosing a smart door lock from the perspective of the fingerprint head, comparing the optical and semiconductor fingerprint heads, the semiconductor fingerprint head has obvious advantages in terms of security and convenience. In the semiconductor fingerprint head, choosing a product with a protective layer can better extend the life of the fingerprint lock.
