When we buy a Fingerprint Scanner, on the one hand, it is to meet our needs, and on the other hand, it is also to choose the quality of the lock. A good company often has no less than 5 high, medium and low fingerprint locks for users to choose from.
Users generally choose to use their own products: there are those for entrance doors, divided into metal doors and wooden doors, there are those for user interior doors, which are often seen in wooden doors, and also used for villa gates, etc.
(1) It can be used by multiple people to open the door with fingerprints (there are usually more than one or two people in a house or office), and the product quality should be stable and have good performance;
(2) It can be used to open the door with different permissions (it is impossible to give the owner, the nanny, and the cleaning tools the same door opening management permissions);
(3) It can freely increase or decrease the number of fingerprints for opening the door (it is convenient for the nanny to use her fingerprint when she leaves);
(4) It is best to have a query record function (you can check the door opening record at any time, which can sometimes become key evidence, and generally requires a display screen);
(5) It should have a proper password function (after all, the fingerprint part is an electronic part and may break down. In temporary situations, the owner can use the password to open the door). When choosing, try not to choose a product that overly emphasizes the password function. After all, passwords are not as secure as fingerprints. Usually there are two types: 4 keys and 12 keys.
