QR code experiment: 9 brands at the Mall of America on Black Friday
Wednesday, November 30th, 2011I’ve long been skeptical of the QR code madness among marketers. Sure, I’ve read all sorts of numbers around QR code adoption–good and bad. But many of the studies still pin *understanding* (not adoption) of QR codes in the 30 percent range. So, I tend to think, as a rule, QR codes are pretty over-hyped among marketers.
