QR code reader/QR scanner - QR codes make life much easier if you receive a large amount of information in insufficient space to place it, whether it's a product in a store, a receipt, a website, an email address, contacts, text or other. You have the opportunity not only to scan other people's codes to view them inside the application, but also to create new QR codes yourself. It is enough just to fill in the code with data, check its contents by viewing and optionally add a logo or make a full copy of the product.
