How to distinguish between good and bad fingerprint locks? It is also easy to distinguish between good and bad fingerprint locks, because the good ones on the market are much better than the bad ones.

Here are some judgment principles for purchasing:

(1) Try to go to the site to experience and then buy;

(2) If you can't experience it, you can refer to the brands and models already used by acquaintances;

(3) Buy products from regular manufacturers.

So how to judge the quality of fingerprint lock on the spot when purchasing?

(1) Weigh first

The fingerprint locks of regular manufacturers are generally made of zinc alloy. The weight of this material is relatively large, so it is very heavy to weigh. Fingerprint locks are generally more than 8 kg, and some can reach 10 kg. Of course, it doesn't mean that all fingerprint locks are made of zinc alloy. Pay special attention to this when purchasing.

(2) Look at the work

Fingerprint locks made by regular manufacturers are of excellent workmanship. Some even use IML technology. In short, they look beautiful and feel smooth without paint falling off. The use of materials will also pass the test, so you can also look at the screen (if the quality of the display screen is not high, it will be blurred), the fingerprint head (most of the fingerprint heads use semiconductors), the battery (the battery can also look at the relevant parameters and workmanship), and so on.

(3) See operation

The fingerprint lock of regular manufacturers has good stability and smoothness in operation. So we need to operate the fingerprint lock from beginning to end to see if the system is better optimized.

(4) Look at the lock cylinder and key

All regular manufacturers use Class C lock cylinders, so you can also check this.

(5) See function

Generally speaking, if there are no special needs (such as networking), we recommend that you buy a fingerprint lock with simple functions, because this type of fingerprint lock has few functions, but it has been fully tested by the market and is quite stable to use; If there are too many functions, there may be many risks. However, it depends on personal needs, which does not necessarily mean that multiple functions are not good.

(6) It is better to test on site

Some manufacturers will bring relevant professional test tools to test electromagnetic interference, current overload and other phenomena.

(7) Please identify regular manufacturers

Because regular manufacturers can guarantee your product quality and after-sales service.

(8) Don't be greedy for cheap

Although some regular manufacturers also have cheap fingerprint locks, their materials and other aspects may have been deleted, so it is necessary to check whether they are suitable for themselves. Most of the low prices in the market are of poor quality or lack of after-sales service, which needs our attention.
