The rapid advancement of digital technologies has significantly transformed traditional business models, particularly in the hospitality and food service industry. Conventional café management systems rely on printed menus, manual order taking, and cash-based billing processes, which often result in longer waiting times, order inaccuracies, and limited customer engagement. To address these challenges, this research proposes a QR-Based Digital Café Menu integrated with Secure Online Payment and an Intelligent Recommendation System. The proposed system enables customers to scan a QR code placed at the café table to access a web-based digital menu, place orders directly through their smartphones, and complete transactions securely using encrypted payment gateways. The integration of secure HTTPS protocols and tokenization mechanisms ensures protection against unauthorized access and financial fraud. Furthermore, a hybrid recommendation engine analyses user behaviour, order history, and popular menu combinations to provide personalized suggestions, thereby enhancing customer satisfaction and increasing average order value. The system follows a client-server architecture that ensures scalability, reliability, and efficient data management. Comparative analysis between the traditional manual system and the proposed digital solution demonstrates significant improvements in order processing time, reduction in error rates, payment efficiency, and overall service quality. The findings indicate that the implementation of a QR-based digital café system not only modernizes operational workflows but also supports contactless service trends and digital transformation in small and medium-scale food businesses. The proposed model presents a practical, secure, and scalable approach for future-ready café management systems.
