Secure, Scalable In-App Payment Integration for Delirest

The Challenge

Delirest, the Hungarian branch of Central Europe’s largest workplace hospitality and contract catering group, aimed to digitalize the dining experience at office-building restaurants with a mobile app that enables seamless self-service meal payments and real-time access to dining information.

The solution needed to support multi-country deployment, integrating market-specific payment methods such as the SZÉP card, Hungary’s most widely used fringe benefit. Ensuring secure, high-performance transactions across different payment ecosystems was critical.

Our Solution

We designed and developed the entire Delirest mobile app and middleware, ensuring a robust connection between the frontend and Delirest’s backend systems. The payment infrastructure was tailored to meet regional requirements, providing:

Hungary

Balance top-ups via bank cards, SZÉP card, and Apple Pay, with in-restaurant payments facilitated through a QR-based Delirest card system.

Romania

Instant, direct in-app payments without the need for preloaded balances.

PSP partnership

We partnered with leading payment service providers, implementing a secure, real-time transaction framework across both markets.

The Result

The Delirest app now delivers a secure, high-availability payment experience, optimized for multi-country operations. With scalable architecture, seamless real-time transactions, and strict security compliance, the solution ensures a frictionless self-service dining experience while maintaining uninterrupted performance during peak hours.
