Why do you need to keep a mechanical key for Fingerprint Recognition Time Attendance?

 Many people often have such doubts when they come into contact with Fingerprint Recognition Time Attendance, and even wonder why they still need to keep mechanical keys for Fingerprint Recognition Time Attendance. Necessity.

To put it simply, Fingerprint Recognition Time Attendance with a mechanical key is like an airplane with an autopilot function with a manual pilot design, just in case. This is because the current Fingerprint Scanner are powered by batteries, and when the batteries run out, if you do not pay attention to replacing or charging them, you may not be able to enter the door through fingerprints, passwords, etc. at critical moments. At this time, if you have a mechanical key, you don't have to worry about not being able to enter the door.
It must be reminded that as a door lock, the Fingerprint Scanner is closely related to the safety of the family, so leaving a mechanical key is also a national standard requirement. Just ask, if some major accidents such as fires, earthquakes, etc. have taken place, but at this time you encounter the embarrassing situation of no electricity, then the mechanical key may be a life-saving straw. Therefore, Fingerprint Scanner must have mechanical lock holes and mechanical keys, otherwise they cannot enter the market. So keeping the mechanical key is not too LOW, but considerate.
It is worth noting that the current Fingerprint Scanner all adopt a concealed keyhole design, which is perfectly integrated with the panel. If you do not observe carefully, it is really difficult to find the position of the keyhole, which increases the time cost for thieves to steal. With the C-level lock cylinder, alloy panel and explosion-proof alarm function, it can effectively prevent violent lock picking. So keeping the mechanical key will not affect the appearance, not to mention the high practicality.
