Hotel Mobile Keys: Confirm NFC and Bluetooth with the Provider

A phone with NFC and Bluetooth is not automatically a supported hotel room key. The hotel and its access-system provider must support the exact mobile-key service, device and credential setup.

Identify the approved service

Ask the hotel which app or wallet, operating-system version and radio method it uses. Confirm how a guest receives, activates and revokes an authorized key. Do not treat copying a physical card's identifier as a supported mobile-key process.

• Use the provider's test account or an authorized room credential.
• Check provisioning, normal unlock and credential expiry.
• Verify documented locked-screen and offline behavior.
• Keep the hotel's approved fallback for a rejected or unavailable key.

Current hardware reference

The R4-T listing confirms NFC and Bluetooth 5.0. Those are hardware starting points, not evidence of certification by a named hotel-lock provider.

Keep the result service-specific

Use the NFC workflow guide to organize the device side of the trial. Retain the hotel, provider, app and phone versions with the accepted result. This article reports no hotel-platform integration or completed lock test and makes no universal room-key compatibility claim.
