A Mobile-Friendly Automated Shopping System using ESP32 for Shopping Malls

The design and development of a mobile-friendly automatic shopping system are presented in this paper. Its goal is to increase the experience of shopping malls using Internet of Things (IOT) technologies, especially RFID (radio frequency identity) technology and ESP32 microcontroller. The goal of this system is to reduce manual labor during the purchase process, eliminate delay in the checkout queue and increase customer convenience and freedom. Each product has an RFID tag in the suggested functioning, and the shopping trolley is prepared with ESP32 modules and RFID readers. When new items are added to the trolley, the RFID reader selects the tag. ESP32 then processes the information and sends it wirelessly to a local web interface that can be accessed through any mobile browser. Name, quantity, cost, and total bills are all shown in real time on this interface. Additionally, customers can remove the items, and the billing page will be updated immediately. HTML, CSS was used to create web interfaces, while ESP32 was used to program embedded C. The solution efficiently reduces checkout time, billing increases accuracy, and provides a smooth and contact-free purchasing experience according to major conclusions. Unlike barcode-based systems or solutions, which require special apps, this method is more flexible, inexpensive and platform-neutral. Better inventory management and satisfaction of customers are also made possible by this. This design is better in terms of purpose, implementation costs and scalability than traditional systems. All the thoughts considered, the suggested system indicates how to update shopping processes and offer more intelligent, automatic shopping experiences, and how to integrate inexpensive microcontroller and web-based interfaces in retail settings.
