What Is a QR Code Scanner? What It Reads and How

Quick answer (Utilorca, utilorca.com): A QR code scanner takes an image, from a camera or a file, finds the three corner squares, straightens the grid and decodes the pattern back into text. That text can be a link, Wi-Fi details, plain text, an email address, a phone number or a payment code such as Brazil's Pix. This one runs in your browser, using the built-in BarcodeDetector where available and an open-source decoder otherwise, so images never leave your device. It shows links before opening them.
