working prototypes. I think it would be much more difficult to do this than you might think.

some Issues are - The amount of poison needed, how it would be delivered ( either the RFID device would be intravenous, and thus really small, or under the skin, and thus not be able to deliver the poison as easily. I don't think it is impossible, just difficult.

The real danger with these things is the possibility that the people with the RFID device would not know it is deadly, since already similar large devices have been used - most notably in Erie PA, where a man was fitted with an explosive collar, linked to a cell phone. The cell phone went off, and Ka boom. It would be easy to fit peole with an ankle bracelet type device that would do the same thing.
