In this fast-paced world, shopping malls and retail shops play a crucial role in enhancing human comfort. However, traditional billing systems create inconvenience by causing long queues during the checkout process, leading to significant time consumption. To address this issue, a new system called Real-Time Cart Checkout Using RFID and IoT has been developed. This system integrates the Internet of Things (IoT) and RFID technology, where an Arduino microcontroller works with an RFID reader to scan products equipped with unique RFID tags. Upon scanning, the product data is sent to a mobile application via a Bluetooth module. The app then retrieves matching details from a web server or database, automatically updating the pricing and product list in real-time. Users can manage their selected items efficiently, and the cart enables them to view the total amount directly in the app. By streamlining and automating the shopping experience, this IoT-based smart shopping cart significantly reduces checkout time, enhances convenience, and improves the overall retail experience.
