RFID BASED SMART CART

Even though E-Commerce has grown exponentially in the past few years, sales made from retail still account for around 85% of the total sales made. Among the difficulties faced by customers, one difficulty is lining up in a queue to follow through with the billing process. The goal is to develop technology that can meet all the needs of the customer while simplifying the billing process and saving the time of the customer. The proposed method is to have the customer directly process products and bill them in the trolley instead of waiting in a queue for long periods. The customers have to add the products after a short scan in the trolley and when they’re done, the amount will be displayed in the trolley. The customer can also log in to the website which will display the list of all the products added and their amount. Here we use RFID cards and RFID readers with Microcontroller to build the Smart Shopping Cart project. The cart information and total value will be displayed on the OLED. Each RFID card is associated with a certain product and an RFID reader is installed in the cart, which reads the product details like Price and Product details and sends the details to the microcontroller. The total cart value that is displayed on the OLED paves the way for easier payment with the concerned organization.
