QR CODE BASED CAFETERIA FOOD ORDERING AND PAYMENT SYSTEM

Abstract: Traditional methods of placing food orders and settling bills in restaurants often lead to confusion, errors, and unnecessary delays. To address these challenges, a QR code-based food ordering system has been proposed to streamline the ordering process. Customers can scan a QR code available at their table using a smartphone, which instantly provides access to the restaurant’s menu. They can then select and customize their orders without waiting for a waiter. This system also allows secure and convenient bill settlement directly through the customer’s device, enhancing overall efficiency. The traditional approach—where waiters manually take orders using pen-and- paper or printed menus—can lead to miscommunication between staff and customers, and often requires customers to wait for service. By leveraging QR code technology, these issues can be mitigated, providing a faster, more accurate, and user-friendly ordering experience.
Moreover, the system benefits restaurant staff by enabling easy management of menus and real- time tracking of orders. Since smartphones are widely used today, implementing such a system ensures accessibility for nearly all customers. Overall, the QR code-based food ordering system offers a practical and modern solution to improve both customer satisfaction and operational efficiency in restaurants.
