Boy, that’s a LOT more than I would have anticipated. Maybe I live under a rock but I rarely see QR codes. I wonder what percent of US mobile users have seen a QR code, bet it’s not a lot… that would make that 14MM users a huge percentage, relative to those who have seen a code:-)
On a similar note, have you seen the Autonomy Aurasma application yet? Extremely cool! Here’s a YouTube video demo. Basically, it turns the entire offline world into a potential QR code. Take a look, it’s worth it!
