A sample code from ScanLife on the NAB website
For some folks, QR is nothing new. But for others, they’re unfamiliar — and seem to be popping up like dandelions this spring. For instance the observant may have noticed the strange square glyphs appearing on official NAB Show advertisements.
QR or “Quick Response” codes are similar to the bar codes seen at the store or the UPCs on products. The QR glyph is designed to be read by a scanner; conveniently, many smartphones have them (which makes the system attractive to marketers and explains why more peeps are suddenly aware of them).
Once read, they can impart all sorts of information. Anything from a Web address to text and data can be embedded into the seemingly random arrangement of little black squares.
QR codes can also be seen in non-NAB Show instances such as magazine ads. The QR code is popular in Japan and South Korea but is only lately proving to be active in the United States.
