Fingerprint lock is mainly unlocked by identifying fingerprint. Generally, optical imaging method is used to record fingerprint through processor and convert it into digital or current signal for recording and comparison. It mainly records the orientation, direction, ridge line and fingerprint characteristics (spiral, short grain and other characteristic information). Everyone's fingerprints are different, so fingerprints are a good choice as personal identification information.

Due to wear, aging, unclear appearance and texture, the fingerprints of the elderly even become lubricated skin, and some of the fingerprints disappear. Therefore, the amount of information recorded in the fingerprints is less, and the comparison success rate is low. Therefore, the elderly generally do not advocate the use of fingerprint lock. If they do often lose their keys, use fingerprint lock. Perhaps the old man's fingerprint identification is no problem. The fingerprint is clear. His ideas are as follows.

The elderly use fingerprint locks:

Buy a fingerprint lock with strong fingerprint identification. Ordinary fingerprint locks have poor optical imaging, and unclear fingerprints have vague imaging and lower recognition rate. Maybe semiconductor fingerprint recognition, such as fingerprint unlocking on mobile phone, face recognition and iris recognition.

Try to carry the door card with you, or smart identification bracelet. As a spare door opening tool for fingerprint identification failure. Maybe take the key with you. If you can remember the code, it's good. Maybe record the code as a phone number and store it in the phone address book.

Select the smart door lock, which can be unlocked through the smart phone.

Therefore, when selecting the fingerprint lock for the elderly at home, we should investigate the elderly's fingerprint. After the mobile phone fingerprint is better, maybe other fingerprint identification equipment, test whether it can be identified successfully frequently. Maybe take the old man to the mall to buy the door lock to see which one has a high recognition rate. If fingerprint identification is difficult, it is better not to buy fingerprint lock, or buy a variety of door opening methods. If you have a good memory, choose a secret code to unlock, use a smart phone to unlock, etc.
