Abstract: This paper presents the design and implementation of an IoT-based smart shopping cart that aims to enhance the retail shopping experience and streamline the checkout process. The system utilizes RFID technology to track purchased items, where RFID cards are used by customers to add products to the cart, with options to add, remove, or finalize the quantity using dedicated buttons. A 20x4 LCD display provides real-time information on the purchase session, helping customers track their items. To prevent theft, the cart is equipped with Industrial IR sensors that detects unauthorized item additions during the shopping process, triggering an alert through a buzzer. Once the shopping session is complete, the final bill is sent to the customer via GSM, and payment can be made through various online methods, including UPI, wallets, and credit/debit cards. After payment, an invoice is automatically sent to the customer's mobile phone. Additionally, the system uses Adafruit IO to store and analyse daily shopping data, providing valuable insights for the storeowner, such as sales trends and customer behaviour, via the ESP8266 module. This solution demonstrates a modernized approach to retail shopping by reducing the time spent at checkout and offering convenience to both customers and shop owners. The paper delves into the system architecture, component integration, and the potential scalability of the design for large-scale retail environments.
