Chi-Huang Hung, Ying‐Wen Bai, Je-Hong Ren · 2015
This design integrates the near field communication (NFC) reader of a smartphone device with the door lock control system to provide a convenient single button operation. This design also offers three operation modes to the user in order to allow a one-time password with a time stamp permission to match the user's password to thus enhance the door's security. The door lock control system is fixed on the door, and also provides both the sleep state and the standby state to save power consumption for a long time operation.
