Here is a little known caver fact....one of our own Texas Cavers, El Coyote of 
North Texas, was at the forefront and was instrumental in the development of 
the Mobil speed pass now used by Exxon.....

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?
