Use mobile authorization to support different users, changing tasks, and temporary access needs.
Improve Traceability
Unlocking actions can be managed and reviewed through the system, making access easier to follow.

What Do We Mean by NFC in This Locking System?
Here, “NFC” is not just a tap-to-unlock feature or a simple way to read information. It supports close-range interaction between the phone and the lock, including access verification, data exchange, and energy transfer during unlocking. The phone helps power and activate the lock, so the lock body can work without a built-in battery.
