Shopping at malls is becoming daily activity in various cities . Among the difficulties faced by the customers one difficulty is to follow queue through the billing process. Though their intention is just to buy one or two products, the process of billing would become very difficult and time consuming. As per our survey money and average time spent on each customer is high especially in overcrowded supermarkets. The main aim is to satisfy the customer and also reduce the time spent on the billing process where the billing process will be done in the trolley rather than waiting in a queue even for one or two products. The smart trolley consists of Raspberry pi, LCD display, DC Motor ,IR Sensor ,RFID Reader, Wi-Fi module and ESP32 micro controller. This system would prevent the problem of long queues at the billing counter. For the ease of customer automatic billing system will be proposed in which the cost of each product will be calculated through smart trolley and displayed on LCD. Thus it will not only save the time of the customer but will provide hassle free shopping for the customers.
