Design and Development of a Smart Shopping Cart System

In big shopping malls to purchase things in the shop there will be a huge crowd in holidays and the crowd will be more during offers and discounts period. People buy more things on those days. After finishing purchasing, he/she should go for bill counter for billing purpose. The biller will bill the things by using barcodes and it is a time taking process. If it continuous it will lead to make long queues in the billing area. This research work is used to avoid this problem. To overcome this problem the product should have RFID tags and the shopping trolley should have LCD screen and RFID reader. When customer puts some product in the trolley means it automatically detects the product, product name and the amount will be shown on the LCD screen. If you don't want the product then you will take away from the trolley, and it will automatically remove amount of the product from billing. The trolleys (Cart) first detect whether the mode of shopping is online or offline. And the total amount will go to the billing system by Zigbee module and IOT so that it can save more time and avoid crowding and queues. Online shopping means it requires network.
