| Video: RFID stands for Radio Frequency IDentification RFID stands for Radio Frequency IDentification, a technology that uses tiny computer chips smaller than a grain of sand to track items at a distance. RFID "spy chips" have been hidden in the packaging of Gillette razor products and in other products you might buy at a local Wal-Mart, Target, or Tesco - and they are already being used to spy on people. Each tiny chip is hooked up to an antenna that picks up electromagnetic energy beamed at it from a reader device. When it picks up the energy, the chip sends back its unique identification number to the reader device, allowing the item to be remotely indentified. Spy chips can beam back information anywhere from a couple of inches to up to 20 or 30 feet away. Some of the world's largest product manufacturers have been plotting behind closed doors since 1999 to develop and commercialize this technology. If they are not opposed, their plan is use these remote-readable spychips to replace the bar code. RFID tags are NOT an "improved bar code" as the proponents of the technology would like you to believe. RFID technology differs from bar codes in three important ways: 1. With today's bar code technology, every can of Coke has the same UPC or bar code number as every other can (a can of Coke in Toronto has the same number as a can of Coke in Topeka). With RFID, each individual can of Coke would have a unique ID number which could be linked to the person buying it when they scan a credit card or a frequent shopper card (ie, an X;b>...X;/b> |
