Abstract: Traditional retail checkout processes are often characterised by inefficiencies, leading to long queues and a decrease in customer satisfaction. This paper proposes "Smart Cart," an end-to-end automated billing system to streamline the in-store shopping experience. The proposed solution utilises a modern web technology stack-MongoDB, Express.js, React, Node- to create a responsive user interface and a robust backend. Key features include real-time barcode scanning through a device camera or hardware integration, dynamic cart management with budget tracking, and a secure wallet-based payment system. To guarantee transaction integrity, the system implements a checkout verification algorithm that cross-checks the software cart data against the hardware sensor data, such as weight and item count. This system also integrates accessibility options and an AI-powered chatbot for nutritional analysis, thus demonstrating a highly scalable and user-centric approach toward the automation of retail.

Keywords: Smart Cart, Automated Billing, Internet of Things (IoT), React.js, Node.js, Generative AI, Web Application, Retail Automation.
