Receiving a key generated electronically on their smartphone, previously identified and authorized by the system, they can unlock the assigned doors from the JustIN Mobile app by selecting the appropriate key. Technologically cutting-edge, JustIN Mobile means the end of lost key hassles, expenses and waste. Plus, the technology isn't limited to one building or hotel room - it can also be used by staff and users on multiple sites for any kind of access types like main entrance doors, elevators, car park barriers, meeting rooms, etc. Combined with user-convenient features such as user friendly design or multi key possibilities to use the same app in different buildings, locations and for different applications, JustIN Mobile access control technology simplifies card issuing, fob and traditional PIN code management that can be lost, forgotten or broken by offering flexibility for diverse applications.
