Inf fact our business cards have a QR Code in the back containing a VCard. :) Also, we're working in an extension to our mobile app where the QR acts as a "command" and the user carries a few QR codes in a keychain like holder, saving them from typing some data or going through menus. It's an usable and compatible way of encoding text graphically. Esteban A. Maringolo ps: There is also a way to encode a QR with a image/logo inside, but I don't know how that works.
