[Jottings] Engadget Barcode Password Hack

So here I am trying to catch up on all the great Engadget Podcasts. They're now all downloaded onto my Tablet PC, I've got the head phones on and listening to each in turn.

I'm on #3 now and this just cropped up. I needed to make a note of it so I don't forget. File under "Things to look into". At 14mins in, there's talk about "scanning" bar codes with mobile phone cams and then it checks the price with Amazon or whatever. Nothing new there. But an interesting idea about storing passwords. You create a impossable to remember password (for something that's important but you're not going to need often, like "84hdkn349df7286kdjh764sk439wpreg", convert that to a bar code. Print out the bar code, stick it on a card and keep it in your purse or where-ever. When you need the password just "scan" the barcode and you have the password.

Of course you don't tell anyone what the bar codes are for though. And I'm pretty sure you could hack the barcode reading software to just rot13 the results and then shift it all 2 ascii values up or whatever anyway, just to be sure your bar code results aren't off the shelf.

Anyway something to play with later.
