Shopping is easy, but waiting for a money counter makes shopping a boring and boring job. In addition to a very busy pace, cashiers invoicing with barcode scanners take too long and form long lines. This innovative project consists of an automated billing system that can be added to your shopping cart. This automatic payment system consists of an RFID reader controlled by Arduino. Each time a shopper puts an item in the shopping cart, it is recognized by the RFID module and displayed on the LCD along with the item's price. As the shopper goes on adding products, all products are detected by the module and therefore the price will increase accordingly. In case if customer changes his/her mind and doesn`t want any product added in the trolley he/she can remove it and the price added will be deducted automatically. At the end of shopping the shopper will press the button which when pressed adds all the product along with their price and gives the total amount to be paid. At exit for verification the shopkeeper can verify the products purchased with the help of master card. Hence this technique is an appropriate method to be used in places like supermarkets, this will help in reducing manpower and helps in making a better shopping experience for customers.
