2011 minus 1994 equals 17. So there have been 17 years since Denso Wave created their Quick Response codes for Toyota. Now there are hundreds of apps for the iPhone that read or create them.

My prediction is that in another 17 years smart phones will snap a photo of a web page, a product, a pin on a map, a movie poster, a page in a catalog, or whatever, and using optical character recognition and artificial intelligence, will automatically create an SMS file (contact info), a product file, or a link to a movie in IMDB. So, 2011 plus 17 equals 2028.
