RFID cannot be tracked via satellite. It is a low-power close proximity technology. It's limited to 10's of feet distance.\
RFID can't tell anything about where it's been between scanning points... it has no GPS type of capability. (It's interesting to note though that your cell phone can be tracked to within a few hundred feet, whether or not you're talking on it, if you're in a city. A bit less accurate if you're outside of a city. Some pnones have GPS built-in, and your location can be fairly well pinpointed with those. Government regulations required being able to locate phones)
RFID can't be used as a 'bug' to listen in on conversations. RFID usually requires an external power source (the reader) to operate. (Some have built-in battery, but these are larger devices) and without an internal battery they can't transmit outside of the range of the reader. Other bugs do exist though that are quite small, but this is a different technology.
RFID doesn't work well on or in metal devices.
There's probably more, but that's what I can think of right now.
