Yes, the fingerprint lock is not only convenient, but also equipped with mechanical performance devices to prevent theft. The Ministry of Public Security requires that any door lock, such as fingerprint lock, password lock, hotel induction lock and remote control lock, must carry the machine key to prevent the lock from being out of power or malfunctioning, and the door can be opened with the machine key. According to the classification of anti-theft performance, popular fingerprint locks are divided into ordinary fingerprint locks and anti-theft fingerprint locks. There is not much difference between the ordinary fingerprint lock and the original electronic lock, which mainly adopts fingerprint authentication, but it cannot be used on the existing security doors in China. This kind of fingerprint lock has no hook of heaven and earth pole, so it is impossible to use the world anti-theft system of security door (some imported fingerprint locks on the market do not meet the national industry standards and can only be used for wooden doors).
