Smart Cart with Automated Billing System

Technology has changed so much, so is the rate of people of all ages who are attracted to electronic gadgets. In many industries, electronic devices such as smart card readers, barcodes, and RFID scanners are increasingly used. Supermarkets also need these kinds of gadgets. Currently, every person in the mall purchases the product placed in the trolley. Upon purchase, the person will have to stand in a queue for billing. In the billing process, an employee scans each product’s barcode and bills it to the final [5]. This process can take a lot of time and it can be even worse on holidays, special offers or weekends. To overcome this, a smart way to shop in malls has been developed. Each product has an RFID tag instead of a barcode. The Smart Trolley features an RFID reader, LCD module. When a person places any product on the trolley, it is scanned and the product’s cost, name, and expiration date are displayed. The total cost will be added to the final check out bill. Utilizing sensors and distance, the trolley autonomously follows the customer throughout the store, maintaining a safe distance and avoiding obstacles. This feature ensures a hands-free shopping experience, allowing customers to focus on selecting products without the need to push or control the trolley.
