Automatic Billing Trolley for an Enhanced Supermarket using RFID

Many customers find it challenging to wait in a lengthy line for the billing of their purchases. This results in financial loss and a subpar bill for the incorrect consumer. In grocery stores or supermarkets, trolleys are utilised to make shopping easier. By automatically identifying the products being added to the cart and providing the relevant information on the user interface, the suggested smart cart can make the shopping experience easier. Shopping malls are still popular, even if it is common to see individuals getting excited about online shopping via e-commerce websites. There are many different types of shopping carts available in malls and shopping centres. This study presents a technologically-assisted intelligent shopping cart that can recognise products. The primary objective of this effort is to reduce wait times in congested supermarkets and other shopping centres using an innovative cart system that makes use of RFID technology to provide an intelligent approach to the billing process. The project's primary focus is the smart cart gadget. It consists of an RFID reader, a GSM module, an Arduino microcontroller, an LCD display, and switches. Every item that is put into the cart will be able to have a bill generated by the system. It will be simpler to skip billing lines in shopping malls with the offered method. The suggested design's conventional queuing system for billing generation makes shopping easy and enjoyable.
