Fingerprints cannot be recognized, yet there is still such an operation?
However, some users may enter their fingerprints in a hurry, resulting in low-quality fingerprints. The fingerprint lock that was finally installed may not be recognized during use and may be rejected. If this situation occurs, how should it be resolved? The editor will tell you the method:
Problem 1: Fingerprints are worn and unclear
The solution is to re-enter the previously recorded fingerprints or re-enter them again. You can use the fingerprint lock management permission to enter the system, clear your fingerprints, and then re-enter clearer fingerprints. It is best to keep several more, so that in case one fingerprint cannot be recognized, other fingerprints can also be recognized.
Problem 2: Unable to recognize when fingers are wet due to humid weather
Before using fingerprints, dry your hands to keep them dry and moist (but without water). This way, removing oil and keeping fingers free of water ensures the highest quality fingerprint input! When using it normally, try to keep your fingers and fingerprint collection area clean and tidy.
Question 3: The fingerprints of the elderly and children are blurry, and the recognition is not sensitive
Elderly people vary from person to person. Currently, most elderly people have no problem with fingerprint recognition, but there are also some elderly people whose fingerprints become increasingly blurry or cannot be seen clearly due to age and years of hard work. This is related to the fingerprint recognition rate. If it is a normal fingerprint, it can definitely be recognized, but if the fingerprint is relatively shallow, it will be difficult to recognize. Children's fingerprints may not be fully developed, and there may be situations where they cannot be recognized. It is recommended that elderly people and children use other door opening methods if their fingerprints cannot be recognized. Therefore, for this situation, it is recommended to use magnetic cards or passwords to unlock for convenience.
Problem 4: Fingers are too dry, fingerprint lock cannot recognize them
If the fingerprint cannot be recognized due to being too dry, we can place the finger near our mouth and let it breathe before entering the fingerprint to make it moist, or wipe the finger on a greasy or relatively moist place such as the forehead to make your finger more moist. Usually, this can solve the problem of fingerprint dryness.
Possible reasons for the fingerprint lock not being able to open include problems with fingerprint lock recognition, or unclear fingerprints that prevent recognition. Hands were not washed thoroughly, and there were colored oil stains on the fingerprints, causing them to be unrecognizable; As long as you wash your hands clean or re record the fingerprint of the fingerprint lock, you can also switch to another unlocking method, and so on.
