Security is the biggest advantage of intelligent fingerprint locks. It is understood that the average person's fingerprint repetition probability is 1 in 5 billion, and after the age of 8, the fingerprint basically remains unchanged, so the fingerprint has uniqueness and non replicability. On the basis of the reliable and accurate identification provided by fingerprint technology, and the ability to reset and delete fingerprints, the quality and safety performance of an intelligent fingerprint lock are measured, mainly reflected in the service life of the door lock. Durability naturally extends the service life of the door lock. 
Convenience "is an advantage reflected in intelligent fingerprint locks, but consumers' needs need to feel convenient from physical products to situational experiences. This is a manifestation of the leap from quantity to quality. In terms of product convenience, intelligent fingerprint locks can be used without carrying keys, bidding farewell to the era of key opening.
However, consumers hope that the intelligent fingerprint lock can provide them with more convenient experiences at the moment of opening and closing the door. This is something that intelligent fingerprint lock manufacturers must attach importance to, especially in opening up the civilian market. Without visible convenience, consumers will not be able to recognize the added value brought by intelligent fingerprint locks.
