How Mobile Key for Hotels Works
Mobile key for hotels usually works by creating a digital key tied to one booking. It is sent to the guest’s phone once the booking is made or the guest checks in.
Guests then unlock their door with Bluetooth or NFC. They don’t need to visit the front desk for a card.
Wallet keys are a newer version of this. Guests keep their room key in Apple Wallet or a similar phone wallet, not in a hotel app.
This option is starting to appear at some properties as more lock makers add the links it needs.
Mobile hotel key systems usually support unlocking through:
a hotel-branded mobile app
Bluetooth links to matching door locks
NFC for tap-to-unlock access
wallet keys stored in a phone's wallet app
