ribit,
re: "get hold of about a million of em with your own id and then inject em into as many folks as ya can find."
Maybe you're joking. But if so, your joke at least suggests that you're thinking. That's good.
Unfortunately, your suggestion won't work.
RFID is inexpensive, and it is everywhere. It could be on your hair, injected under your skin, in your stomach, on your clothes, on your car... right now. And why would you only have one? They're so cheap (and becoming cheaper) that you might well be bugged with MANY of them. Thousands, maybe.
There's more than one type of RFID tag. Some have batteries. Some have storage. Most are powered by the radio waves that read them and can only broadcast a few feet. But others can transmit great distances. Between RFID and GPS technology, whale movements are now being tracked FROM SPACE.
But here's the real gotcha: RFID tags include a serial number, a CPU, and programming. There's nothing that says that a tag MUST respond when in the presence of a detector. It could stay silent until it receives a broadcasted signal... and then it would reply. That's how *I* would design it, and I'm no genius. You can bet that secure, tiny, virtually undetectable RFID tags have already been created.
So, in short, you can't fool RFID by planting "a million of em with your own id." You'll never know your own id, or even if you're broadcasting.
I'm hoping it will one day be possible to jam the signals with some sort of a personal device. But I have my doubts f that. It would take an awful lot of power, and the benefits wouldn't be obvious. (When it works, nothing seems to happen.) Since there's no telling where the transmitters even are (our shoes, our hair, our car, our coffee cup, our money, etc) it would be pretty tough to figure out where to put the jammer.
Aargh. Thinking about what's coming makes my head hurt. We're going to hell in a handbasket.
