Smart Shopping Card with Automatic Billing System using RFID & Arduino

In this project, we will build a Smart Shopping Cart with an Automatic Billing System using EM-18 RFID Module & Arduino. The project is super easy to build and requires only a few electronic components. In this system, every product in Mart will have an RFID tag, and every cart will be having RFID Reader. When a product is scanned, the price is automatically added to the billing system. The LCD Display in this project shows the item name along with the price.

A supermarket is a place where customers come to purchase their daily using products and pay for them. So there is a need to calculate how many products are sold and generate the bill for the customer. When we go to a shopping cart for shopping, we have to work for selecting the right product. Also, after that, it is hectic to stand in line for billing all the goods. Hence, we are proposing to develop a smart shopping cart system that will keep the track of purchased products for billing using RFID and Arduino.
