In today's fast-paced world, shopping malls are seeking ways to enhance customer convenience and streamline the shopping experience. The proposed project focuses on the design and implementation of an IoT-enabled intelligent and user-friendly trolley system using the ESP32 microcontroller, RFID technology, Blynk app, and GSM module. This system automates the process of adding products to the shopping cart, calculating the total bill, and notifying customers of their total costs through a mobile app and SMS.Each product in the store is tagged with an RFID card, and as a customer adds a product to the trolley, the RFID reader integrated into the trolley scans the product’s tag. The system instantly fetches the product details, including the price, and updates the total bill in real-time through the Blynk app on the customer’s smartphone. A buzzer provides audio feedback for each successful scan. At the end of the shopping experience, the final total is sent to the customer's phone via SMS, using the GSM module.This intelligent system eliminates the need for traditional checkout counters, making the shopping process quicker and more efficient for both customers and store management. The integration of IoT and RFID technology ensures seamless operation, while the use of the Blynk app offers a user-friendly interface for real-time monitoring of purchased products. This solution is not only cost-effective but also scalable, making it adaptable to various retail environments.
