Q: How does FLEXIPASS improve the guest experience?

FLEXIPASS enables frictionless, app-free digital access, eliminating physical key cards and reducing front-desk wait times. Guests enjoy fast check-in, secure entry, and modern convenience — all through a personalized digital experience.

Q: Can I use FLEXIPASS if the guest’s phone is offline?

Using the FLEXIPASS API, you can delete, update or issue a new mobile key in real time. Simply call the respective endpoint (e.g., /deleteMobileKey or /updateMobileKey) with the key ID. The system instantly synchronizes changes across all connected locks and user devices.
