Automatic billing system for shopping cart based on RFID tag

Abstract

In daily life, the purchases of glossaries in supermarkets are increased by a number of people. In the bill section, the customers may be waiting for few minutes to get the bill and payment process. The present system at the store should be maintained in line with the scanning sight of the barcode affixed to the product. The central concept of the proposed system aims to save the customer's time at the billing counter and helps to purchase their desired quality products according to preferences in a comfortable and relaxed manner in shopping malls or supermarkets. RFID has not required a line of sight technology to scan the product. It can also track multiple objects at the same time. The RFID reader attached to the cart and an RFID tag added to each product if it is in the specified range sends the feedback signal to the reader, and the shaufing list is transmitted wirelessly to the server and also on the cart screen, where the updated facts appear whenever the customer adds, or removes any product on or from the cart and automatically displays the revised bill. The payment can be made either by cash or online payment gateways.
