Quick-response (QR) codes might be a key way for brands to attract or retain customers, according to a new ScanLife study. Results from the study showed that 62 percent of the scans converted to further engagements such as Web clicks, with 95 percent of the codes driving at least some action. When presented with relevant content, consumers increasingly preferred the convenient, immediate, mobile-optimized experience that QR codes enable from physical media such as print ads, product packaging and store displays, according to the study.
