[0002] With the development of society and the advancement of science and technology, people's lives and work are increasingly dependent on electronic devices. For families and businesses, security issues have become an important issue that cannot be ignored. Traditional keys can no longer meet people's needs for security. Therefore, electronic door locks came into being, which have higher security and convenience. There are many types of electronic door locks, such as fingerprint recognition door locks, facial recognition door locks, smart key door locks, etc. These door locks use biometric technology to open the door lock by identifying the user's specific biological characteristics. Compared with traditional keys, electronic door locks are more convenient and safer. For enterprises, electronic door locks can also improve security and convenience and reduce the safety hazards caused by manual management. For example, when employees go to and from get off work, they can quickly enter the company through fingerprint recognition door locks. Facial recognition door locks can prevent employees from forgetting to carry keys or losing keys. In addition, electronic door locks can also be used for residences. Traditional keys can no longer meet the needs of modern homes.
