QR Codes

QR Codes (Quick Response codes) are barcodes that can be read by a dedicated QR code reader. To use a QR code, you need a smartphone that can run an application and that has a camera. You can check out QuickMark - an application that supports many different kinds of phones (iPhones, many Android phones and Blackberries) to read QR codes - it's a free application that is available through your phone's application marketplace.

Check out Snap My Info for those of you who have phones with a camera and email, but no applications.
