Digital Guest Registration & Signature Platform

Large hotel operations depend on property management systems for critical reservation and guest data, but parts of the check-in experience can still rely on manual or paper-based workflows.

The solution needed to integrate with Oracle OPERA while coordinating multiple tablets across the front desk. A receptionist had to be able to initiate a registration for a specific guest and route it to the correct device without exposing the session to every tablet connected to the system.

Network interruptions, reconnects and duplicate submissions also had to be handled without losing guest data or processing the same registration multiple times.

We designed and developed a digital registration workflow connecting the hotel's PMS, backend services and front-desk tablets.

Each tablet is treated as an individually registered device. When reception initiates a registration, the backend creates a dedicated signing session and signals the selected device in real time through WebSockets.

WebSockets are used as the real-time control channel, while authenticated REST APIs handle guest and reservation data. This keeps device notifications lightweight while giving the application a clear and auditable API boundary for sensitive operations.

The tablet experience allows guests to review registration details, update required information, provide GDPR-related consents and complete a digital signature before the registration is synchronized back into the hotel workflow.

Hotel front desks cannot depend on perfect network conditions, so the workflow was designed around persistent signing sessions rather than transient WebSocket messages.

A signing session maintains its own lifecycle and can be recovered after a device reconnects. WebSockets notify devices that new work is available, while the backend remains the source of truth for the current session state.

Submission requests use an idempotent processing model so retries can be performed safely without creating duplicate registrations or repeating downstream side effects.

The integration layer keeps Oracle OPERA-specific communication separated from the application workflow, making the core registration platform easier to maintain and allowing additional hospitality systems to be integrated behind the same architecture.
