Fingerprint lock is a kind of intelligent lock that uses the fingerprint of the finger as the identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. It is generally composed of electronic identification and control and mechanical linkage system. , The uniqueness and non-replicability of real-time fingerprints determine that the fingerprint lock is a relatively safe lock among all current locks, so what are the reasons for the fingerprint lock not being opened?
1. The fingerprint can be modified with a password, delete it, and then add it.
2. If the battery power is low, you can buy a battery for power supply, and then unlock it with a fingerprint.
3. Whether it is the recent work on the hand, which has caused serious fingerprint wear, or the hand has not been cleaned, there is a color oil on the fingerprint, which makes the fingerprint unrecognizable.
4. There may be a problem with the driver, or the fingerprint recognition software, or more likely the hardware. You will see whether the fingerprint recognition software icon in the taskbar is displayed normally. .
