MADISON, Wis. — Radio frequency identification, or RFID, is a new technology that might revolutionize the way businesses and even governments track objects.
And while experts say RFID holds tremendous positive benefits for both industry and consumers, questions remain about how invasive this technology could be for people.
RFID technology uses radio waves along with microchips and antennas called tags to give an object a unique number, similar to the idea of a Social Security number for items. Receiving devices called readers then remotely track the object from a distance and download information about it, WISC-TV reported.
