One of the most useful tools for air traffic safety is the transponder — used by all commercial airlines and most private aircraft. When the air traffic control radar scans the airplane, the transponder does more than just act as a reflective target. Its electronics sense the radar signal and send back its own highly informative message giving such data as the airplane's altitude. RFIDs at Wal-Mart do essentially the same thing, but when interrogated by a scanner, the tags send back information on product codes, shipment dates, destinations — whatever information is required for tracking.
The main groups of RFIDs are passive and active with the difference being the way power is supplied to the outgoing signal. Passive devices, such as price tags that have the RFID printed on them, take the tiny amount of power collected by the antenna, and reflect it back to the scanner along with bits of information. Active RFIDs, like those used to identify cars as they pass through a toll booth, have some type of battery power allowing them to send back a much stronger signal with more information.
Some RFID chips are now being inserted into people. A July 22nd story in Wired News by Todd Lewan describes how a surveillance company, CityWatcher.com, embedded microchips and antennas — described as being "as long as two grains of rice, as thick as a toothpick" — in the forearms of two workers involved in protecting high security police data files.
Like wealth, information is power. Early writers on the Holocaust wondered how so few Nazis could round up, imprison, and murder so many Jews. Later it was found that the Third Reich knew names, addresses, relatives, friends, and even ancestors of their victims before the first Gestapo agent knocked on a door in the middle of the night. Without such important data available to the killers, any attempt at mass murder would have be total chaos.
No doubt embedded RFIDs would be "voluntary" at the outset, somewhat like "voluntary drug tests" and "voluntary compliance" with tax laws. Inexorably, once the camel's nose was under the tent, we could see arguments for inserting the chip at birth - hey, no more hospital mix-ups! And the information would doubtlessly escalate: today, health information; tomorrow political affiliations, income, "anti-State activities." While there may be cases where such devices are warranted, e.g. medical alert data for emergency responders or identifying child molesters, the use by government of these devices should be opposed with at least the same tenacity used in opposing restrictive gun laws.
