What Makes a QR Code Different From a Barcode
A Quick Response (QR) code is a two-dimensional matrix barcode, invented in 1994 by Denso Wave, that encodes data both horizontally and vertically instead of along a single line like a traditional barcode. This lets a single QR code store hundreds of times more information, including full URLs, WiFi credentials, vCard contact details, or a pre-filled WhatsApp message, all of which this tool supports as dedicated input tabs.
