QR codes are popping up all over. In Washington, DC, QR code stickers are being place around the city. If you have a smart phone with a QR app (there are lots and lots of them for every smart phone with a camera) you scan the QR code with your phone to get bus arrival information.

FOX is using them to promote their new shows by displaying a QR code at the very end of TV ads. When you scan them you are taken to a special web page about the show.

I have seen them on business cards, in the windows of stores to provide a link to the store’s site or the stores contact information and hours, or specials available only to QR code readers. Soon we will be putting a QR code at the beginning and end of every PowerPoint slide show at conferences to provide contact information and links to the PowerPoint online. This could really take off if enough people have the app to read the codes and people start using them.

Keep your eyes out and see if you can spot any QR code.
