RealID calls for every person in the U.S. to carry a new ID that contains an embedded microchip and antenna that broadcasts your name, birth date, identification number, and even your photo to card readers, including those in ATMs and at every cash register. The card can broadcast your personal info to persons and institutions without your knowledge or consent. This technology also allows the gov. or whoever to track you, as the chip will broadcast the cardholder's presence to each reader he passes.

Plan to simply refuse to get one? The govt. is now seeking to legally tie voter registration to the need for a new drivers license, see: Election Law, Voting Rights...
Then in 2008, when Real ID goes into effect, it's either get the ID or don't vote. Also, the Fed plans to require the ID in order to board an airplane.
"Citizen shakedowns" like the one in Denver , are also happening elsewhere in the country. Check out Miami's "Random Shows of Force," a new operation in which police will show up at random public locations and demand the ID of every person. See: Miami Police Take New Tack to Terrorize the public
