First of all, an intelligent lock should be designed by the product designer according to the user's needs. The designer's design concept includes the appearance design, function design, circuit design and algorithm design of the intelligent lock. Smart lock design also includes the designer's accurate grasp of the user's pain points, and its characteristics also make it a choice for more and more people.

Can not copy the traditional mechanical lock key, as long as a few minutes, low cost can get the key you want. Fingerprints are special features of human body, and their complexity is enough to provide sufficient features for identification; The fingerprint lock has the advantage that the fingerprint can't be copied, so there is no need to worry about the key being copied.    

You don't need to take a key when you go out. You don't need to worry about losing the key or changing the key when the nanny changes it. A person's fingerprint remains unchanged for life. You can use it for life by inputting it once. And a person can enter fingerprints of different fingers. Touch to open, reverse lift to lock.     

This situation often appears in movies. You can crack it by prying open the circuit board and connecting the handheld device. It also happens in China. It mainly depends on the design of the lock. Responsible manufacturers will adopt the design of separating the front and rear panel circuits. The cost is relatively high, but even if you pry open the front panel, you can't crack it, because the main digital circuit is behind. At present, there are only a few responsible manufacturers doing this, because it will bring additional costs. The above-mentioned Bida adopts dual circuit design.
