CueCat certainly comes to mind. The difference, of course is that this hardware is akready wdespread, and portable. The idea of having that thing by your desktop computer to read codes vs. Urls you could type in was pretty lame. On the other hand, same deal with this - agreed I'd rather simply type in an address. Security wise, this is the ultimate URL obfuscation. I could go around sticking stickers over everyone elses QR codes to send you all to my virus/spam/phishing kingdom, right?
