Various talking heads have called this "The year of the QR code," and said that the codes will revolutionize the print industry. Does anyone remember the Cue Cat? It was a device that came out in the 1990s and readers were going to use it to scan bar codes in magazines, which would take them to innovative websites. Sound familiar? QR codes have a big leg up on the bar codes that were read by the Cue Cat. The technology to use them is already in most people's pockets. We would assume this type of access might play a major role in the QR code's success, but that's only part of the story. The rest of the picture shows why we shouldn't get too attached to the QR code. Much is promised. Little is delivered. Remember last summer when Calvin Klein unveiled a giant QR code on Houston Street in New York? Probably not. The code took people to yet another video of alienated, attractive, semi-dressed 20-somethings traipsing around urban landscapes. Yawn. Where haven't we seen that before? That was the advertising equivalent of "I shaved my legs for this?" Get the full story at AdAge
