Design and Implementation of Direction Controlled Trolly for Smart billing using IoT

Customers can control the trolley using mobile app and move it without any difficulty. There are total of five controlling options Front, Back, Left, Right and Stop, this makes the customers shopping easy. After making a full purchase, you need to go to the billing counter to make the payment. There is a long line at the ticket office, payments are a time-consuming process, to eliminate the time-consuming nature of payments, a billing system will be implemented in the trolley. The mechanism consists of RFID Reader and a tag which is placed inside every product, when a customer places a product in a shopping cart, he/she should ensure that he/she place the tag near the reader so that the product is read by the billing panel and it will show the bill amount to the reader. The trolley does have an RFID reader attached to it. Every time we order it, the cost of the item will be added to the final bill. whenever we place it. As a result, billing will take place within the cart directly. It will be shown on a LCD display & web page.
