In malls trolleys are required to carry a number of goods around as you shop. The customer has to pull the trolley from rack to rack, collecting items .Also the customer has to keep track of how much he is spending in order to fit it in his budget. To avoid this entire headache of pulling the trolley, waiting in billing queue, thinking about budget, we are designing a smart trolley that would reduce the customer’s effort and making shopping easier. The smart trolley follows the customer while purchasing items and it maintains a safe distance between customer and itself. When a product is kept in the trolley, it automatically calculates the bill. The final billing will be a lot easier as no separate billing counter will be required.

Keywords: Ultrasonic sensor, Barcode scanner, microcontroller, RFID Reader, Accelerometer.
