Lock means locking and closing. It is a necessary object used to block public space and private space. As early as 3000 years ago, the ancients in China used locks. It is an important manifestation of private ownership. Its intention is to maintain the safety of their own space and goods. Therefore, when choosing finger lock, we need to consider security. So how to judge the security of fingerprint lock? There are several key objectives:

A. Security level, this is the most crucial! At present, the anti-theft lock has three levels: A, B and C. The difference between the three levels is the opening time of anti skills. Class A is the opening time of anti skills for 1 minute; Class B 5 minutes; Level C 10 minutes. Don't underestimate these minutes. According to the investigation of the Ministry of public security, 90% of thieves will abandon it if they can't unlock it in one minute. Therefore, we should choose locks above level C. The longer the opening time of anti-theft skills, the better, for example, those that can reach more than 200 minutes.

B. The fingerprint system, needless to say, is also very crucial. After all, it is a fingerprint lock. If even the fingerprint system is unprofessional and unsafe, there is no need to consider it.

Now, many enterprises use the first generation optical fingerprint system, and the optical fingerprint system has expired many years ago. Now the safest and most advanced fingerprint identification system is the biological living fingerprint identification system. The Apple phone we touch every day uses the biological living fingerprint system. Now let's look at the difference between optical fingerprint system and biological fingerprint system: basically, living fingerprint system can eliminate all the hidden dangers of fingerprint security.

C. Virtual code can be useful to avoid code leakage.

D. Select the fingerprint lock with anti disassembly alarm and misoperation alarm locking function.

E. It has anti lock function.
