A: The possible reason is 1 bad motherboard; 2 internal characteristics of the LCD. In this case, contact the supplier and return to service.
Q: Some users' fingerprint attendance often fails to pass the verification. How to solve this problem?
A: Some of the following situations may cause some employees to use the fingerprint or not be able to use attendance at all:
Fingerprints on some fingers are flattened; fingers are wrinkled too much and often change; fingers are severely peeled; water or unclean fingers are stuck on the finger during verification. Users with unrecognized fingerprints can delete the fingerprint and register it again, or register another finger. When registering fingerprints, such users need to choose to use better-quality fingerprints (less creases, lack of skin, and clear fingerprints), try to make the fingers contact the fingerprint collector with a larger area, and perform comparison tests after the registration is completed; Register a few more backup fingers. In addition, our attendance machine provides a 1:1 comparison and password attendance function for this purpose. You can set these employees to use 1:1 attendance or password for attendance.
