IOT-Based Smart Cart

In today’s fast-paced world, shopping at large malls often results in long queues and billing delays. The smart shopping trolley addresses this by integrating RFID and Bluetooth technology to automate the billing process, reducing wait times and the need for staff. Each product is tagged with an RFID tag containing a unique EPC (Electronic Product Code). As items are added or removed, the RFID reader scans the tags and updates the total cost in real-time, which is displayed on an LCD screen. This helps customers track spending and stay within budget. The system includes an RFID module, microcontroller, and Bluetooth module for seamless data processing and wireless communication. When the customer presses the billing button, the total bill is transmitted to their Android app via Bluetooth, eliminating manual checkout. Unlike barcode systems, RFID supports non-line-of-sight scanning and can detect multiple items at once, improving transaction speed and accuracy. The system enhances retail automation by enabling contactless billing, reducing human effort, and increasing efficiency, security, and scalability—making it ideal for modern smart retail solutions.
