This past year, a book called Brand Digital by Allan Adamson placed an EZcode on the back cover. It linked directly to the book's Amazon page where someone could read user reviews, and buy the book in one click.
This uses existing content from Amazon and its already formatted for mobile without doing a thing. It really couldn't be much easier - and it probably shouldn't!
So next time you see a 2D code, remember that you may be entering a virtual store with an offer that's too good to be true. The only problem is that you may leave with your virtual wallet a little lighter.
