Mythbusters and RFID
I'm not a big fan of these kind of shows (there are so many), because the little time they have for each episode can hardly make for a truly informative viewing. Though he makes excellent points about exactly that. So btw, RFID is hackable - obviously, it's technology :p So get to the books! HACK THE PLANET!
added: thanks ed for posting this in the comments. Here is an RFID Mythbusters episode, it's basically propaganda. The youtube comments are surprisingly conscious for once.
