        abstract = {The retail industry is undergoing a significant transformation driven by the need for enhanced customer experience and operational efficiency. Traditional queuing systems at checkout counters remain a primary source of customer dissatisfaction and time wastage. This research presents the design and implementation of an IoT-based Smart Shopping Trolley aimed at automating the billing process and eliminating long waiting times. The proposed system integrates Radio Frequency Identification (RFID) technology with the Internet of Things (IoT) to create a seamless shopping environment. Each product in the store is equipped with a unique RFID tag containing essential product information. The smart trolley is integrated with an ESP8266 NodeMCU microcontroller, which acts as the central processing unit and provides Wi-Fi connectivity. An MFRC522 RFID Reader is mounted on the trolley to scan items as they are placed inside. Upon scanning, the product details and price are instantly retrieved and displayed on a 16x2 I2C LCD, which maintains a real-time running total of the bill. To ensure system integrity and accuracy, an IR Sensor is utilized to detect the physical movement of items into the cart, triggering the scanning process. Furthermore, a Servo Motor is implemented to provide an automated physical response, such as a locking mechanism or a gated entry/exit for scanned items, enhancing the security of the automated system. Data synchronization is achieved through the built-in Wi-Fi module of the NodeMCU, which transmits the billing information to a centralized server or mobile application. This allows for instantaneous payment processing and inventory management. The system not only empowers consumers by providing transparency in spending but also assists retailers in reducing labor costs and improving throughput. Experimental results demonstrate that the prototype is highly reliable, cost-effective, and capable of significantly reducing the average checkout time compared to conventional methods. This project contributes a scalable solution to the evolving landscape of smart retail environments.},
