Remember that sci-fi scene where Tom Cruise is walking through a shopping mall and the displays are hawking him, speaking directly to his individual tastes? Someday soon you may be scanned as you enter (and as you leave) a store to get data from the products that you are wearing or carrying in your purse, pockets or wallet. Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects.
RFID systems consist of a tag, (smaller than a grain of sand) that contains a microchip with a broadcast antenna... and a reader with an antenna that sends out electromagnetic waves. The tag receives them and converts the waves into power from the reader, using it to light up the microchip circuits. The chip then responds to the reader with its data.
The use of RFID technology is called "spy ware" by groups like CASPIAN, Consumers Against Supermarket Privacy Invasion and Numbering. They fear the following:
- The purchaser of an item will not necessarily be aware of the presence of the tag or be able to remove it;
- The tag can be read at a distance without the knowledge of the individual;
- If a tagged item is paid for by credit card or in conjunction with use of a loyalty card, then it would be possible to tie the unique ID of that item to the identity of the purchaser; and
- Tags create, or are proposed to create, globally unique serial numbers for all products, even though this creates privacy problems and is completely unnecessary for most applications.
Most concerns revolve around the fact that RFID tags affixed to products remain functional even after the products have been purchased and taken home, and thus can be used for surveillance, and other nefarious purposes unrelated to their supply chain inventory functions.
"Supermarket cards and retail surveillance devices are merely the opening volley of the marketers' war against consumers. If consumers fail to oppose these practices now, our long-term prospects may look like something from a dystopian science fiction novel," says Katherine Albrecht in RFID: Tracking everything, everywhere.
OK! Now here's the fun part... if you have $20 to blow.
It seems that RFIDs are already being inserted in the latest US currency. A fellow named Dave says he was recently scanned at a truck stop and his cash set off an alarm. Dave decided to try to deactivate the chips.
"We chose to 'microwave' our cash, over $1000 in twenties in a stack, not spread out on a carasoul. Do you know what exploded on American money? The right eye of Andrew Jackson on the new twenty, every bill was uniform in it's burning... Isnt that interesting?"
Ho, ho, ho! Have a Merry Christmas!
