Easy to improve electronically controlled door lock system.

Mechanical door locks for locking and opening doors with metal keys are mainly used in door locks for offices, hotels and apartments. However, the safety of conventional mechanical door locks is poor due to the inability to be lost or undesirably duplicated as a metal key for locking and opening the door. At present, various types of door locks are used for the disadvantages of the conventional mechanical door locks, such as the use of a magnetic card type or a smart card type electronic key to open the door and lock the door lock, to open the door by entering a password, and to lock the door lock. In addition, door locks that can open and lock doors through biometrics that are inherent to the specific features of the human body, such as voice recognition, fingerprint recognition, and face recognition, are being actively researched and commercialized.

At the same time, information and communication technologies represented by the Internet and mobile communications are changing the modern lifestyle. In particular, personal computers that use the Internet have been distributed throughout almost all homes, schools, and offices, allowing users to access information through websites, purchase goods through electronic transactions, and exchange messages via email.
