QR CODE BASED GROCERY BILLING WITH EXPIRYALERT SYSTEM

Abstract: The drawbacks in the existing system are, firstly the time required for bill payment is more as the users have to wait in a long queue. Secondly, the users have to move the cart through the entire mall and carry a load of products at their home. One more drawback is regarding the barcode in which less data is stored. An inventive way to improve convenience and efficiency for consumers and retailers alike is the QR Code-Based Grocery Products Purchasing and paying System, which simplifies the grocery purchasing and paying process. This technology makes use of Quick Response (QR) codes to provide a frictionless and smooth purchasing experience. When grocery shopping, the process usually entails picking out things by hand, putting them in a cart, and then going to the checkout counter where a cashier scans each item by hand and creates a bill. This process can take some time to finish, especially during busy periods. Our system enables QR codes to be added to every grocery item in order to get over these challenges. This eliminates the need for a physical checkout by enabling customers to use their smartphones to scan and purchase goods. The data is sent to the server after the user scans and adds the item to the cart, and the bill is created once all the goods have been added. The items are delivered to the user's house, the bill is emailed to his device, and bill payment is completed online. The goal of this project is to create an alarm system that alerts managers and store owners when inventories or items are about to.
