Nowadays, supermarkets are almost developed with much technological advancement. People purchase different items from the supermarkets and put them into a trolley because it is the easiest method used in supermarkets to carry goods.However, throughout the whole process of shopping, customer must push thetrolley manually by their own effort and when it comes to the billing processcustomers must wait in long queues to pay their bills. This is a time wasting process due to the busy schedule of people. To avoid these problems we have introduced an effective and highly advance system. To swamp these problems, Shopping malls use this technique as a strategy to increase the number of purchasers. In big cities, we can observe an enormous flash at shopping malls on weekends. This becomes even more when there is diversity of offers and discount. The prevailing billing system is a bit time consuming. So, we thought of inventing a remedial electronic product to catch-up with this problem. We call it “IOT based Human Guided Smart Cart with automated billing system”. This project eradicating the traditional way of shopping. If this smart system is implemented in hypermarkets, it will reduce the long waiting queue in front of the counter, thus saving the time of customers for a very enjoyable shopping experience. It reduces time by using barcode scanning Technology and improves utilization of resources like manpower. The human following system of shopping trolley is done by using GPS technology localization scheme and Android application. Both communicate via the Bluetooth function. A weight sensor is placed at the bottom of the trolley to provide security and transparency. This system also use obstacles avoidance technique for avoiding collision with other trolleys, humans or any other objects. The Lcd display used in the system displays the details of bills and also customer can remove the unwanted product by selecting the products in the display. In the payment module, the customers get several options like UPI payment, cash or Card.
