QR (Quick Response) codes are graphical barcodes: square black dots arranged in a grid on a white background. Subject to the installation of an app, they can be scanned by devices such as smartphones and digital cameras and call up text, videos, audio snippets, and other digitized content. QR codes can be printed or pasted onto any flat surface: paper, walls, screens, or windows.
