Know about QR codes?  If you’ve spent any time around Android apps on the web you may have seen them.

 

They look like this


 

Wikipedia has a pretty good write up:  http://en.wikipedia.org/wiki/QR_Code

According to the page these codes can store up to 4,296 characters and even have the capacity for error correction

I found a great site for generating FREE QR codes.  I used it to generate the one above.  http://qrcode.kaywa.com/

Google used a few of these during its recent i/0 conference:  http://googleio.appspot.com/qr

Wonder if kids are passing notes with these in school yet???
