QR code: Standards, History, Applications & Art

A QR code, short for quick-response code, is a type of two-dimensional matrix barcode invented in 1994 by Masahiro Hara of the Japanese company Denso Wave for labelling automobile parts. It features white and black squares within a square grid featuring fiducial markers on the corners, readable by imaging devices like cameras, and processed using…
