In June 2011, 14 million mobile users in the U.S., representing 6.2% of the total mobile audience, scanned a QR or barcode on their mobile device, according to comScore, which released results from a mobile QR and barcode scanning study on 12th August 2011. The findings reveal that males dominate the use of QR codes. More than 60% of males—the highest percentage ranging in age from 18-34—scanned codes in June, of which 36.1% have a household income of more than $100,000 annually. Overall, users were most likely to scan codes found in newspapers or magazines and on product packaging, either at home or in a store.
