Mark Donovan, senior vice president of mobile and senior analyst with comScore, believes that the popularity of QR codes is ramping up because of the increasing popularity of smartphones. “I think that we’re seeing things like QR codes just start to reach critical mass,” said Donovan. “Today, one in three people in the U.S. owns a smartphone. It’s a good and fairly ubiquitous way to reach those people and there’s still some novelty to it, which can be interesting to consumers.”
