2D Barcode Patch

P8TCH is a cool site that allows you to take 2D barcode, and make an actual fabric patch for your bookbag, etc, which points to a url.

"Think of it as a short URL you wear. Each 2x4-inch, velcro-backed p8tch has a Mysterious Commando Design on the top, and a QRCode on the bottom ....Each p8tch comes with a secret passkey that lets you set the redirect target of the URL as often as you like. So it really is like a TinyURL, except one that you can control."

Also note ZXing, where you can encode your name/address into a 2D barcode

Hack a Day has a note on "How to put your logo in a QR code"

and NPR (on 09.26.11) points out that "Few Consumers are cracking the QR Code"... except for well off, middle age, white men....
