This document describes a proposed smart shopping cart system that uses RFID technology. The system aims to streamline the shopping and checkout process. RFID tags would be attached to all products in the store. As shoppers add items to their cart, an RFID reader in the cart would automatically detect and record the products. When the cart reaches the checkout area, the items and their details would be transmitted to the cash register via LIFI and the bill would be automatically generated for the customer. The document discusses the system components, including the microcontroller, RFID reader, LCD display, LIFI transmitter and receiver, and power supply. It also provides background on RFID technology and reviews several other existing smart shopping and RFID applications
