ScanLife releases its Q4 2011 ScanLife Trend Report, which looks at the busiest quarter of the year for mobile barcodes, and draws comparisons between 2011 and 2010. The data in this report was pulled from the ScanLife Reporting Platform; it represents traffic from both two dimensional barcodes (i.e. QR Codes) and UPC barcodes. The report shows that the momentum gained over the last two years shows no signs of abating, with Q4 2011 seeing more scans than all of 2009 and 2010 combined. It also includes data about user demographics, marketer adoption, and media placement.
