I'm pretty sure the nano just needs a poke and then it'll spit out whatever you've configured it to do. I got one and used it for a little while to unlock my computer, by just having it spit out a static password on touch. The issue with this of course is that your password is now visible in clear text just by placing the key in a USB port, opening up a text input, and then touching the key. It was convenient, but very insecure obviously. Maybe it would be useful to you though.

In fact how about this, you can have mine – for free. I never use it anymore, and if there's a chance it'll help you I'm happy to just send it your way. It's just collecting dust at this point anyway.
