The smart shopping trolley system helps customers while shopping. The trolley has an automatic billing system and it follows the movement commands provided by the user by using an android application that was installed in customers mobile. The products purchased by the customer and their cost will be automatically updated to the android application through the local area network (LAN) created using Bluetooth and that bill will automatically send to the administrative system in the shop through the Internet of Things(IoT). This helps customer by replacing tedious process of pulling and pushing the trolley and saves time spent in the billing counter. The automatic billing process can be achieved through radio frequency identification (RFID) tag and reader and to enhance efficient movement of trolley the obstacle avoidance has also been implemented.
