FAQ

What is a mobile key?
A mobile key is a digital credential that turns the guest's phone into the room key, bypassing the front desk entirely. It activates after completing online check-in and uses Bluetooth or NFC to unlock the door.
How does a mobile key work?
A mobile key works through a Bluetooth or NFC connection between the guest's phone and the room lock. After online check-in, the hotel app sends an encrypted signal to the device, which opens the lock when the phone is held near it, without needing a physical card or front desk visit.
Why is a mobile key better than a traditional plastic key card?
A mobile key reduces front desk queues, saves the cost and waste of plastic key cards, and provides a safer contactless experience. For example, a medium-sized hotel can eliminate up to 20 000 plastic cards per year while speeding up guest arrivals.
