QR Codes: Cracking the 
(QR) Code

eMarketer reports usage of QR codes is up over 180 percent in the first quarter of 2011. 
For retailers, the question isn't whether to incorporate QR codes into their marketing strategy, it's how to do it.

QR Code Case Studies
Best Buy has led the way with QR code use, starting in the summer of 2010 when it began adding QR codes to its weekly circulars. From there, QR codes began appearing on product information labels in Best Buy stores, and a QR code reader was included in the company's mobile app. By scanning a QR code at the shelf edge, consumers are taken to Best Buy's website, where additional information such as product comparisons is available. This is all done within Best Buy's mobile app, allowing the retailer to control the communication and, most importantly, track what the consumer is looking at.
