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

Here are some principles for you to judge your purchase:

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

(2) If you can‘t experience it, you can refer to the brands and models already in use by your acquaintances;

(3) Purchase products from regular manufacturers.

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

(1) Consider first

The normal manufacturer‘s fingerprint lock is generally made of zinc alloy. The fingerprint lock made of this material is heavy, so it is very heavy. Fingerprint locks are generally more than 8 jin, and some can reach 10 jin. Of course, it does not mean that all the fingerprint locks are zinc alloy, which should be paid special attention to when purchasing.

(2) Look at the workmanship

Fingerprint locks of regular manufacturers are of excellent workmanship. Some even use IML technology. In short, they look beautiful, feel smooth and won‘t lose paint. The use of materials will also pass the standard, so you can also look at the screen (the display screen will be fuzzy if the quality is not high), the fingerprint head (most of the fingerprint heads are semiconductor), the battery (the battery can also look at the relevant parameters and workmanship), and so on.

(3) Look at the operation

The fingerprint lock of a regular manufacturer has a stable and smooth system operation. So we should operate the fingerprint lock from beginning to end to see if the system is optimized well.

(4) Look at the lock cylinder and key

Regular manufacturers all use Class C lock cylinder, so you can also check this.

(5) Look at the function

Generally speaking, if there is no special demand (such as networking), we recommend that you buy fingerprint locks with simple functions, because these types of fingerprint locks have few functions, but they have been fully tested by the market and are quite stable to use; However, 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 bad.

(6) It‘s better to test on site

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

(7) Please identify the formal manufacturer

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

(8) Don‘t be greedy

Although regular manufacturers sometimes have cheap fingerprint locks, their materials and other aspects may have been deleted, so we need to check more if they are suitable for us. Most of the low price stores in the market are of poor quality or have no after-sales service, which should be noticed
