gota mcrowave? does anyone wanna try this? i'm sceptical.
wouldn't you be able to feel the RFID tag in the bill?
surely they arn't THAT small. (the tags i've seen in libery books or store items are at least 0.5mm thick imo)
Even if they installed RFID tags in cash, it's not like they could track it around the world. Passive RFID has a range of ~5m. Meaning that it's useful for detecting counterfeits (pass the bill through a scanner, no beep = not real).

That's what they're telling you. I'm not saying it isn't true, but I'm also not ready to assume they can't track them either.
i've read about some interesting technologies that can do what Red Pheonix suggests. it's so cheap and small that the usa navy is looking into this technology to put on EVERY SINGLE ITEM IT OWNS so that it can take easier inventorys.
it's been a while since i read about it, but i remember it involves using static as a carrier signal.
What's what "they" are telling me? Passive RFID (the kind that functions without its own power source) can only function within ~5m of a reader. This is per Texas Instruments. What "They" (I assume you mean the T-men) are saying is that there is no RFID; I'm saying that if there is, it's passive and therefore can't be tracked around the world. However, it can be tracked at certain points, or -- its most likely use -- used as an anti-counterfeiting measure.
The only people who have any real concern are counterfeiters. "Tracking" would be the same as recording the serial numbers that uniquely define every dollar bill produced.
