Keywords:Smart trolley, Arduino, keyboard, Remote, Antenna, LCD, RFID
This paper focuses on the design and implementation of a Smart Trolley Shopping in supermarkets to solve difficulties of customers whilst waiting in queues for billing. The trolley is designed to develop market services and make them modern, healthy and easy to use. The remote controls the movement of the trolley automatically and reduces the load on the client during pulling the trolley. In addition, it helps in saving money by not buying unwanted products, with the help of the Liquid Crystal Display in the trolley, which shows on the update of purchase limit. In this work the client writes the amount they have via the keypad, where the amount appears on the liquid crystal screen. The product used is then checked for price and RFID details. This information is sent to RFID in the product via radio to RFID reader which determines the radio waves. It has an antenna bar for receiving and transmitting data. It also contains a small memory for detailed information of up to 256 bytes. The total cost is summarized by the scanner for materials stored in memory, sent to Arduino. The cart moves according to the client's movements when shopping and then moves to the left, right, forward, backward, or even stops through the buttons. If the customer purchases the products more than the amount recorded on the keyboard, an alarm will serve as a reminder to the customer that he/she has exceeded the purchase limit. The smart trolley is characterized by the speed of accounting compared to conventional accounting and provides a quality service. It reduces congestion at the cashier counter and shortens the time and waste of effort during the accounting process.
