IOT BASED SMART SHOPPING TROLLEY WITH AUTO BILLING SYSTEM USING RFID

Abstract

By automating checkout and cutting down on inefficiencies, the Smart Shopping Trolley is an Internet of Things-enabled technology that aims to improve the shopping experience. It is powered by an Arduino micro controller and has a bar code scanner, LCD display, buzzer, and push button. Bar code scanning is used to register products, and the LCD shows real-time updates. While the system creates a QR code for mobile payment and prints a receipt, a buzzer verifies that the scans were successful. This innovation lessens the need for human workers, expedites shopping, and lowers billing errors. It maximizes productivity and raises consumer happiness in supermarkets and retail establishments
