In the era of digital transformation, our project introduces an innovative solution, the "Smart Cart Shopping with IoT-Enabled Trolley," designed to enhance the traditional shopping experience by seamlessly integrating Internet of Things (IoT) technologies. Our system incorporates cutting-edge devices such as RFID (Radio-Frequency Identification), Node MCU, and an LCD (liquid crystal display), creating a dynamic and intelligent shopping cart. The foundation of our smart cart lies in the RFID technology, which enables automatic item identification and tracking within the cart. Each product is affixed with an RFID tag, and as items are added or removed, the Node MCU microcontroller processes the data in real-time. The LCD display mounted on the cart provides a convenient interface for customers to view their selected items, ensuring a transparent and accurate shopping experience. Furthermore, our system introduces an innovative payment mechanism through a seamlessly integrated web page accessible on the cart. By leveraging QR code technology, customers can effortlessly make payments for their selected items. The QR code, generated dynamically based on the RFID data, can be scanned using a mobile device, directing the customer to a secure payment gateway on the web page. This not only streamlines the checkout process but also eliminates the need for traditional point-of-sale terminals, enhancing the overall efficiency of the shopping journey. To further enhance the transparency and convenience of the shopping experience, our Smart Cart Shopping system incorporates a real-time data pricing feature. As customers navigate the aisles and add items to their carts, the system dynamically updates the prices of each item based on the latest market rates. The LCD display on the cart provides customers with a comprehensive and up-to-the-minute overview of their current bill, allowing them to make informed decisions about their purchases. This real-time data pricing not only ensures accuracy in the billing process but also empowers customers to manage their budgets effectively. The integration of this feature exemplifies our commitment to leveraging technology to provide a holistic and customer-centric approach to the retail experience. In conclusion, our Smart Cart Shopping with IoT-Enabled Trolley represents a significant leap forward in the evolution of retail technology. By leveraging RFID, Node MCU, and QR code integration, we aim to provide consumers with a seamless, secure, and efficient shopping experience. The project not only showcases the potential of IoT in transforming traditional retail processes but also lays the groundwork for future innovations in the realm of connected devices and smart retail solutions.
