Worldwide, one billion people have phones with cameras that are capable of reading QR codes. Half the smartphone users in the United States have QR code applications on their devices.
In June, 14 million mobile users in the U.S., about 6.2 percent of the total mobile audience, scanned a QR code on their mobile device, according to a study by comScore, Inc. The study found that a mobile user that scanned a QR code was more likely to be male (60.5 percent of the code scanning audience), skew toward the ages of 18-34 (53.4 percent) and have a household income of $100,000 or above (36.1 percent). The study also analyzed the source and location of QR scanning, finding that users are more likely to scan codes found in newspapers, magazines and on product packaging and do so while at home or in a store.
Send me your favourite QR Ad you have seen ?
IVOR TOSSELL’S VIRAL recent article on QR ads is great… I thinks its important when an author comes across a storey for themselves and uses the technology that than turns into an idea for a storey. So, his question and observations are sound. They do provide a value and additional content, however, have they gone mainstream? I suggest you read his article, scan a QR ad and comment on your experience.
