Mashable writes: "The QR code, or quick response code, is simply a two-dimensional bar code that came into being in 1994 and found a large audience in Japan. Stateside, however, QR codes — while clever for tying real-world objects to online content — have always remained on the outskirts of public awareness.
Nonetheless, we’ve seen QR codes employed for creative purposes. The Detroit Red Wings interactive programs and the giant QR codes in Times Square come to mind. Each of these serves as prime examples of how QR codes could be on the verge of their breakout moment.
What the technology needs in order to finally make it to the mainstream are applications that take the nerd-factor out of the QR code scan, and drive home the potential rewards of seeing a code, scanning it, and then engaging with the served-up content."
