1. Functional safety (virtual password, anti-tailing, anti-cat eye opening, one-key escape, etc.) Utilizing the fast processing CPU to improve the response speed of the switch lock, it can be turned on in one second. The black technology smart fingerprint lock is a new generation of smart fingerprint locks. This kind of black technology lock has a built-in high-performance CPU chip. People only need to store fingerprints in the CPU in advance, and the user can quickly get a response when they open it again. There is no such high-performance chip inside traditional locks, so switch locks are Ask people to do it manually. 2. Information security (information storage, data transmission, biometric point processing, etc.) Use powerful memory to increase fingerprint storage space. Some users worry that the storage space of the Black Technology smart fingerprint lock is limited and cannot store multiple sets of different fingerprints at the same time. In fact, the internal chip of the Black Technology smart fingerprint lock contains powerful memory, which can meet the fingerprint storage needs of a family. With the smart fingerprint lock, the opening records of the elderly and children at home can be accessed in the storage space in real time.
