Wow, excellent dissertation, Rod! Very thorough, yet never stepping over
the line into conjecture.
I, however, will 'conject' that most, if not all, RFID chips in use today employ
magnetic induction, precisely to prevent the sort of eavesdropping that folks
worry about. Case in point, the Exxon One Pass card, which must be
waved within inches of the receiver in order to be read. Seems like a no-
brainer to me, but what do I know?
