Abstract
The IoT based smart trolley is designed using Arduino. The system eliminates the unnecessary time at a queue. In shopping mall shopping is a daily activity in metro cities. User will have to various products and keep them into the trolley & will have to go to the counter for bill payment of all the products. By using barcode reader, the cashier will make the bill at the billing counter. To make a system that can be used to solve the difficulties of customer and save the valuable time of users is the main aim of this project. In the shopping mall all the goods will have beset with RFID tags. When a user will keep the products in the trolley, the code and the weight & the name of product will be detected and the total amount of those products will be saved in system memory, the name of product and total amount is shown on server and it will be sent to cashier counter by wirelesses ESP modules. It would reduce the rush at shopping mall & save the unnecessary time at billing counter. Automatic billing is done through the RFID tag.
