Revolutionizing Dining with Contactless Ordering
We collaborated to build a cutting-edge platform that revolutionizes dining by enabling customers to instantly scan, order, and pay without downloading an app. Our team delivered both web and mobile applications using React Native, React.js, Next.js, Node.js, Express.js, Nest.js, and PostgreSQL, hosted on AWS Cloud for scalability and reliability. The solution integrates seamlessly with existing POS systems, empowering restaurants to increase revenue, reduce operational costs, and gain valuable customer insights. This solution now provides a smooth, fast, and contactless ordering experience for diners while streamlining workflows for merchants, making it a win-win for both sides of the table.
Project Overview
This solution is a next-generation dining platform designed to transform how restaurants and customers interact. With a simple QR scan, diners can view the menu, customize orders, and pay instantly — no app download required. The solution focuses on speed, convenience, and enhancing the dining experience for both customers and merchants. Our role was to provide Web App Development and Mobile App Development services that brought this vision to life with high performance, scalability, and seamless integrations.
The goal of this project was straightforward yet ambitious — create a digital solution that enables a complete restaurant experience from ordering to payment without the friction of traditional processes. The system needed to work instantly via QR scanning, integrate with existing POS systems, and handle high traffic with ease. At the same time, it needed to provide restaurants with valuable insights into customer behavior to improve operational efficiency.
We were tasked with developing both a web application and a mobile application to deliver a smooth, consistent experience across all devices.
Our Approach
We combined technical expertise with a deep understanding of the hospitality industry to create a robust, user-friendly platform. From architecture planning to deployment, every decision was centered on speed, security, and ease of use.
Web App Development
Our Web App Development process focused on delivering a responsive and intuitive interface that works flawlessly on any device.
Core Web Features
- Instant QR Code Interaction: Customers simply scan a QR code at their table to start ordering without logging in or downloading anything.
- Dynamic Menu Display: Real-time menu updates with item descriptions, images, and customization options.
- Secure Online Payment: Integration with secure payment gateways for smooth transactions.
Technical Execution
We used React.js and Next.js for a high-performance, SEO-friendly front-end. The backend was developed using Node.js and Nest.js, connected to a PostgreSQL database for reliability and scalability. The entire solution was hosted on AWS Cloud for robust uptime and performance.
Mobile App Development
Although the concept of this provided solution removes the need for mandatory app downloads, we also developed a dedicated mobile application to extend the platform’s reach and provide a native experience for repeat customers and merchants.
Key Mobile App Features
- Quick Menu Access: Native QR scanning for immediate menu loading.
- Order Customization: Easy modification of dishes, add-ons, and preferences.
- Real-Time Order Tracking: Users can view the status of their orders in real time.
Mobile Technology Stack
We built the mobile apps using React Native, ensuring cross-platform compatibility for iOS and Android. This choice reduced development time while maintaining a consistent experience.
Integration with POS Systems
A critical requirement was smooth integration with existing restaurant POS systems. This eliminated the need for operational overhauls and allowed for:
- Instant synchronization of orders with the kitchen display systems.
- Real-time updates to menus and pricing.
- Centralized reporting for management teams.
Merchant Benefits
Boosting Revenue
The platform encourages upselling through interactive menus, recommended add-ons, and easy reordering. With faster table turnover, restaurants can serve more guests per shift.
Reducing Costs
Automated ordering reduces the need for staff to take orders manually, freeing up their time for service quality improvements.
Data-Driven Insights
Merchants gain access to analytics that reveal:
- Best-selling items.
- Peak ordering times.
- Customer order history.
Customer Benefits
Faster Service
No more waiting for a waiter to take the order or bring the bill. Customers can order and pay the moment they’re ready.
Personalized Experience
Customizable dishes, dietary preference filters, and instant payment create a more tailored dining experience.
Contactless Convenience
Perfect for post-pandemic dining, the contactless approach improves hygiene while maintaining hospitality.
