Scanlife, a provider of QR code services, saw the number of unique users scanning codes through its system triple in the year to March. One reason for the rise is the proliferation of smartphones with high-quality cameras and the corresponding decline in data charges.--
For marketers, QR codes bridge the gap between offline and online worlds. Customers who use them are, in effect, asking to be told more about the company. The success of a campaign is easy to measure by the number of scans. Expect to see a lot more of those funny little black-and-white patches.
