Quick Cart: A QR Code-based Ordering System

Author(s) Ms. M Roopa Sarika, Ms. A Muni Priya

Abstract The food and beverage industry has rapidly shifted towards digitization, driven by changing customer expectations, mobile technology, and the impact of the COVID-19 pandemic. Addressing the need for seamless, contactless, and efficient ordering, this project presents Quick Cart, a full-stack web application that transforms the traditional ordering process using QR code technology, real- time menu management, and secure digital payments.
Quick Cart bridges the gap between customers and store owners, offering an interactive platform for managing the entire order lifecycle—from menu browsing to payment. Customers scan a QR code placed on their table to access the digital menu, customize orders, and complete transactions without staff involvement. Store owners can register businesses, manage menus, and track orders through a user-friendly dashboard. Each business is provided a unique QR code linking to its digital menu.
Built with Node.js and Express.js on the backend, MongoDB for database management, and React.js on the frontend, the system ensures a scalable, responsive, and dynamic user experience. Axios is used for real-time API communication. Payment integration is achieved through UPI and Razorpay, enabling secure and efficient digital transactions, with real-time payment status updates for store owners.
Designed for flexibility and scalability, Quick Cart allows independent management of multiple businesses without data conflicts. Secure authentication ensures data protection. The system supports mobile responsiveness, dynamic QR code generation, error handling, and robust API communication, delivering reliability even on low-end devices.
