Automated Billing to Ease Queues at Shopping Malls through the Implementation of Effectual Gyres

In modern world the super markets are trying to impress the customers using attractive ideas to ease the customer's shopping. The 3s-system is a recent advancement where the process of integrating the RFID technology takes place. In our project we propose an idea where smart shopping system can be implemented by using IoT and Raspberry pi 3b. The RFID tag which is already used in the recent technology is replaced by the barcodes that are assigned to each product. The smart cart consists of a barcode scanner that is interfaced with the Raspberry pi 3b which scans the barcode of the products that are put in the cart and displays the details regarding the product to the customer by using a mobile application. In addition the cart also contains load cells which indicates the weight of each product put in the cart. An unscanned product is recognized by an alarm using a buzzer. The main server consists of all the details regarding the products in the mall and once the shopping is done by the customer, the bill gets updated in the centralized database using IOT. This will reduce the time taken while standing in queues for billing in the checkout.
