Some questions about Fingerprint Scanner

Theoretically speaking, one more function means one more program, so the possibility of product damage is greater. But this is a comparison between manufacturers with the same technical strength. If the technical strength is high, then their products can have more functions and better quality than those with poor technical strength.

It is very useful to manage user rights. Users can freely authorize, allow or prevent certain people from entering. This function is more practical for users who have nannies or tenants at home. When the nanny or tenant moves out, their fingerprints can be deleted immediately so they can't open the door without access rights. On the contrary, if there are new nannies or tenants, their fingerprints can be entered at any time so that they can open the door freely. For a product with such good functions, people will definitely have some related questions. Let`s talk about it with the fingerprint anti-theft lock manufacturer.
1. Is it unsafe if fingerprints are taken away
If you accidentally leave fingerprints on a used glass, will it copy my fingerprints and make my home unsafe? I sincerely advise you, you really think of yourself as the leading actor in a movie, so wake up quickly. Today's Fingerprint Recognition Time Attendance is equipped with a living fingerprint recognition module. Unless he holds you and presses your finger on the lock, it is difficult for me to imagine how to crack it.
Of course, I don't deny that there are fake fingerprint film services now, but you can try to verify it. Anyway, I have tested it and it doesn't work at all. After all, the black technology in this is something that laymen like me cannot learn. If you really understand the key points, I'm afraid there's no need to be a thief anymore.
2. What should I do if the Fingerprint Recognition Time Attendance system runs out of battery
If the Fingerprint Recognition Time Attendance battery runs out, it doesn`t mean you have to sleep on the road. According to standards, all qualified Fingerprint Recognition Time Attendance cards on the market have one hand, and you can use a spare key to open them in extremely hidden places. With Fingerprint Recognition Time Attendance, 99% of people will no longer go out with their keys. Then you can go to the supermarket to buy a 9V battery, then charge it outside, and it will unlock and open the door after a short wait.
3. Even if it is a Fingerprint Scanner, why is there a mechanical key
There is no Fingerprint Scanner, but there is an emergency mechanical key. This is a requirement of the Ministry of Public Security that electronic locks must be equipped with mechanical keys. This is based on safety considerations. If there is an emergency such as a fire, it is safer to have a mechanical key. Emergency mechanical keyholes are generally hidden and will not be used normally.
