The Arduino based smart shopping trolley using RFID RC522 works on the principle of using RFID technology to identify products and add them to the shopping cart. The system consists of an RFID rc522, Arduino Nano, LCD display, RFID cards or tags and power supply. The RFID reader reads the UID of the card or tag attached to the product and sends it to the Arduino Nano, which adds the product to the shopping cart. The LCD display shows product names along with their cost which are added to the cart and the total cost of the purchase.
