Capacitive, scraping and other fingerprint heads that do not emit light after being worn are collectively called semiconductor fingerprint heads, which have the advantages of anti-counterfeiting fingerprint function and fast recognition speed. But the wear resistance is not good, because the hard objects on the body will scratch. Generally speaking, the life span is only equivalent to the life span of a mobile phone, so it is suitable for mobile phones.
Optical fingerprint head is divided into domestic and imported. Domestic optical fingerprint head has a longer service life and better wear resistance than ordinary optical fingerprint head, but the disadvantage is that it does not have anti-counterfeiting function. For example, a fake fingerprint head made of silicone can also enter the system. In other words, others can open your door by copying your fingerprints. But in fact, it is difficult for others to record one of your fingerprints, so it is better to just knock on the door at home. The other is imported fingerprint head, which is currently used by only one in China. This kind of fingerprint head has Korean and American anti-counterfeiting patents, as well as sapphire mirror with hardness similar to Rolex watch, which is very scratch-proof. Of course, the price will be more expensive than ordinary fingerprint heads 1000 yuan.
Therefore, in terms of durability, the optical fingerprint head is better because of its good stability and long service life. If you are worried about the anti-counterfeiting function, use the gold finger code to open the anti-theft fingerprint lock K9 1.
