Increase completion rates, reduce front desk queues, and reach guests instantly on the channels they use most.

Your guests are already on their phones. Your check-in invitation should be there too.

In today’s hospitality landscape, digital guest journeys are essential. With Nonius Online Check-in, hotels can send automated pre-arrival invitations via Email, SMS, and now WhatsApp, enabling guests to complete their check-in quickly, securely, and from any device.

Reaching guests on the channels they use most increases completion rates, reduces front desk congestion, and ensures a smoother arrival experience.

Intelligent & Cost-Effective Messaging

Don’t just send messages. Send them smart. Our platform allows you to orchestrate channels to maximize reach while minimizing costs:

  • Smart Reminders: Send your initial invitation via Email and automatically trigger a WhatsApp or SMS reminder, closer to the arrival date, only for guests who haven’t completed their check-in.
  • Sequential Priority: Define your preferred order (e.g., WhatsApp first, Email as backup). If a guest’s phone number isn’t available, the system automatically fails over to Email to ensure no guest is left behind.

“When we designed this multi-channel engine, our goal was to solve the two biggest challenges in digital check-in: adoption and cost. By allowing hotels to orchestrate between Email, WhatsApp, and SMS, we’ve created a system that is both persistent and cost-effective. It’s not just about sending a message; it’s about reaching the guest where they are, exactly when they need to act, while keeping the hotel’s messaging budget under control.”
