QR codes are two-dimensional images with glyphs of various sizes that store not just numbers, but text. When scanned, your phone extracts the encoded information and can act on it. For example, QR codes often embed URLs, allowing you to scan, say, a parking meter to launch a webpage where you can pay online.
