QR codes may be turning up in more places than ever these days, but are people actually using them? According to market research firm Comscore, at least some of them are -- 14 million in June in the US alone, to be specific, or about 6.2 percent of all smartphone users. As for who makes up that slice of the smartphone market, Comscore says that just over 60 percent are male, 53 percent are between the ages of 18 and 34, and 36 percent have a household income of $100k or more. Folks are also apparently more likely to scan QR codes at home than at a retail store, and magazines and newspapers edge out websites or product packaging when it comes to the top source of the QR code being scanned. So, not exactly an explosion in use, but still fairly impressive for a weird-looking barcode that was rarely seen outside of Japan until a few years ago.
