Optical fingerprinting is wear-resistant, but the recognition rate of fingerprint images on the surfaces of dirty fingers and dry fingers is low, and cloned fake fingerprints cannot be recognized. Semiconductor fingerprint recognition only identifies living body fingerprints, the rejection rate is 0.1%, and the false-positive rate is 0.001%. It can effectively identify cloned fake fingerprints and has high safety. The lock body is very important for the security of the smart lock.
