Or attach it to a piece of steel with the locking mechanism so it
locks into the enclosing hardware for the PC while the poll is open.
It can then be unlocked and removed at the end of the day in plain
sight of anyone who wants to see. Have room on it for a
chain-of-custody sticker where signatures are placed. For even more
fun, make the locking mechanism so that it automatically
(mechanically) covers the USB opening of the thumb drive as part of
the process of removal.

Best regards,
Arthur
