Quick response codes (QR codes) seem to be everywhere. In fact, according to JumpScan, QR code scanning increased 1,200 percent from July to December 2010, with 57 percent of Twitter and Facebook users reporting they scanned at least one QR code in the past year.
It’s no wonder, then, that these two-dimensional (2D) matrix barcodes, which can hold thousands of alphanumeric characters of information, offer you immediate access to what’s relevant.
A quick scan using your iPhone, Android, or other camera-enabled smartphone activates your phone functions such as e-mail, IM, and SMS, or connects the mobile device to a Web browser.
