USB Lock

This do-it-yourself USB lock hack “effectively turns any standard USB thumb drive into a key, which can be just as easily lost or misplaced as a regular key but not as easily duplicated.” Video after the break.

What’s more, it’s not the data on the drive that gets read by the lock, but rather the serial number on a chip, which leaves the rest of the drive free for you to use as you please.
