Digital check-in and mobile keys: a hotel implementation guide

Start with the lock, not the app

Your lock vendor decides what is possible. BLE-capable locks with a mobile SDK support true keyless entry; older offline locks may only support a kiosk-issued card. Confirm firmware, gateway coverage and SDK licensing before designing a single screen.

The five-step flow that works

Pre-arrival prompt 24–36 hours out, with ID capture and payment authorisation.

Room assignment released only when housekeeping marks the room ready.

Key issued to the device, with a card fallback always available at the desk.

In-stay services — dining, concierge, extensions — attached to the same folio.

Express checkout with a digital receipt emailed within seconds.

Operational details people forget

Group and shared rooms need multi-key issuance with an owner who can revoke.

Night audit and folio timing must match the app's checkout window.

Front desk staff need a live view of who checked in digitally, or they lose trust in the system.
