True, but I would take pains to ensure that the 'key' is unique, and
no copies remain if the passive response device fails. Otherwise, the
rubber hose method remains.

Again, the point is that authorized copies of data are cheap, stolen
copies aren't. Chances are, you have a copy of just about everything
that was on that device either at home, at the office or "in the
cloud".

I'd keep it in my wallet, as a wristwatch or as a function on my
phone. It could even be an RFID tag, which means you could likely keep
one in your clothing and not have it trip a metal detector. RFID tags
implement selective responses, too; if so configured, they won't
respond to RFID readers which don't have their address.
