Sofia (ISEO) + FLEXIPASS FAQs
What does Sofia (ISEO) + FLEXIPASS do?
Connect Sofia access technology with the FLEXIPASS guest journey. Check the installed hardware and access software before choosing the key technology.
Which key technologies can I use?
The Sofia (ISEO) + FLEXIPASS integration path lists Webkeys. Your complete platform-and-lock combination must support the selected technology; a provider listing alone does not confirm every installation.
Do guests need to download an app?
Supported Webkeys open in a browser without a separate key app. Mobile Keys require a compatible app; Wallet Keys require a supported wallet and device. Availability depends on your complete setup.
Can this reduce reception queues?
It can reduce the card-collection step for eligible guests when access follows completed check-in. Registration, identity checks, payment and room readiness still need a clear process. Keep staff assistance available.
Plan check-in and checkoutWhat should we confirm before rollout?
Exact lock and reader models, access software, licences and connectivity. Test delivery, expiry, room changes and an alternative access method with FLEXIPASS before going live.
Do we need to replace our locks?
Not necessarily. Supported existing hardware may be usable, but connectivity, readers, software or licences can still need changes. FLEXIPASS reviews the exact installation before recommending a setup.
What if a guest cannot use their phone?
Keep staff assistance and a tested alternative, such as a physical keycard. PIN Codes are another option only where the complete system supports a compatible keypad.
