Just a couple of things before you use this, the script has to be run as 
root, but the hotkey functions run things as you. I tied this script to 
the hotkey fn+f2 which is what turns on and off the card on my machine. 
Ubuntu only supports setuid binaries, not scripts. They do this for very 
good reasons, and you should read up on setuid root and its implications 
before using this. That is why there is a small binary that then runs 
the script that does the work. Quite honestly the way I have implemented 
this is a horrible hack, but it works. Realize also that if your card 
reads out different codes in any way you could end up with a script that 
unloads the module at incorrect times.

It would be great if someone actually new what the state codes from the 
card meant instead of just guessing like I have. If someone does, 
forward them my way and I will attempt to implement this properly in a 
binary and without massive security issues.
