Automatic Billing Trolley

Shopping has bewitched everyone nowadays. Most people visit the nearby supermarkets to do shopping, which causes long queues on billing counters. Hence, we designed a small design to do the billing work fast and accurate. Using this system, we will be able to see the gross prize of the products added in the cart, so that at the counter, customer will not have to scan the products and generate bill. This design will help both the customers and supermarkets. It can be implemented using Arduino Nano, Radio Frequency Identification (RFID) tags and reader module, LCD display and other basic components.
