A device used to read QR codes is typically a QR code scanner, which can be a smartphone camera equipped with dedicated scanning software or an independent handheld device. QR code scanners interpret the encoded information within the QR code, which can direct users to websites, display text, or provide other data. Most smartphones today come with built-in QR code scanning capabilities through their camera apps or specialized applications. This increased accessibility enables users to engage more easily with digital content and services, bridging the gap between physical and digital interactions.
