Smart Door Lock

​ Recurring passcode with cyclic period: Enables housekeepers to clean the room within the valid period, eliminating the need to send new passwords repeatedly.

​ Real-time unlock records: All unlock activity is synced to the app instantly.

​ Network-free password sharing: Passwords can be sent via SMS without an internet connection.

​ Automated timed passcodes: Guests access expires automatically, blocking room entry after checkout. No need to chase unpaid rent—access revocation ensures security.
