Re: Anti-removal/theft protection method - any ideas?

If your hardware isn't done yet, you can use the power supply cord for
that purpose.

Modulate the supply voltage with a stream of data bits. Encode
"unlock" keys into the data stream. Once powered up, your device
waits for a key to be received. If there is no key, it won't work (or
work in a different operating mode).

The power supply can easily be locked away in a physically secure
place, with only the cord available to the operators (and thieves).
Use an uncommon connector type to make sure that no other supply is
used by accident.

If your device doesn't give signs of life before receiving the key,
dumb thieves will just think that their supply is of a wrong voltage
or type.
