Denso Wave has elected not to exercise their patent rights of QR codes and that has encouraged their widespread use in other parts of the world.
The QR code is known for appearing in magazines, on signs, on buses, on business cards, or on almost any object about which users might need information. QR (Quick Response code). Is a type of matrix barcode (or two-dimensional code) designed to be read by today’s smartphones. The code consists of black modules arranged in a square pattern on a white background usually big or small. Although initially used for tracking parts in vehicle manufacturing, QR codes as of 2011 are used in a much broader context. Uses extend from commercial tracking to entertainment and from product marketing to in-store product labeling. Many of these applications target for smartphone users (via mobile tagging).
