Kiosk: Self-Food Ordering System

Project Overview

A leading quick-service restaurant (QSR) chain sought a self-service kiosk solution to streamline ordering, reduce queue times, and enhance the customer experience. Their challenge was managing high-order volumes while ensuring seamless integration with their POS system via QST API and secure payment processing via an external gateway. Magnatesage Technologies developed a Windows-based Kiosk Management System (KMS) featuring real-time menu updates, modifier configurations, and automated backend order processing. The result? 40% faster order processing, increased average order value, and automated admin controls for efficient multi-location management
