What+are+QR+codes?

QR codes connect online and offline worlds: From bus stops and billboards, to augmented reality magazines, QR codes are an advanced bar-code technology that blurs the line between digital and physical space. The idea is that scanning a bar code is much faster than typing a Web address on your tiny smartphone keyboard or touch screen – and way "cooler". These black and white boxes may not be the most visually arresting technology, but it’s what they can do, where they can be placed and how they’re being used that makes QR codes fascinating.  > Help Jimmy Fallon and Stephen Colbert raise money for DonorsChoose.org and Stephen Colbert will sing Rebecca Black's "Friday" with The Roots! > > Jimmy Fallon & Stephen Colbert recently announced that they've become Best Friends Forever (for Six Months) and are generously donating each others' time & money to DonorsChoose.org. > > Last week, Stephen announced that Jimmy had matched Stephen's gift of $26,000 from the proceeds of a Colbert portrait sold at auction.
