Integrated Smart Trolley System: Arduino Nano-Based RFID Billing and Weight Sensor Augmentation

In a shopping mart, imagine ten people waiting in line. If the first five people have many items in their carts, the last person with only one or two items may wait a long time to pay. To address this issue, we introduce an innovative Smart Trolley Billing System using Arduino Nano and EM-18 RFID technology. This system automates checkout and tracks inventory in real-time, enhancing the shopping experience. By seamlessly integrating Arduino with RFID tags, product identification becomes instant, eliminating manual scanning. With features like an LCD screen for transparent item lists and weight sensors for added security, our solution aims to optimize shopping, improve customer satisfaction, and streamline inventory management in retail environments.
