This is called "QR code", a two-dimensional bar code intended to be read by cell phone cameras to instantly access its content. Already it is widely used in Asia, especially Japan, where QR codes are seen everywhere. I am curious to see more uses of QR Code in U.S.
Here are some interesting examples. Take a look how QR codes are used for various branding purposes in Japan.
