^ DoD Announces Radio Frequency Identification Policy


Here's one implementation of RFID that I post for the description of the
device:

http://www.smartcardauthority.com/news1.html
The ASK smart label combines a microchip and an antenna
printed on paper with conductive ink to make a wireless
device that looks and feels like a standard paper label.
Using radio frequency identification (RFID) technology,
customized readers can read and write data contained on
the C.label chip. The printed antenna eliminates the
need for a wire coil antenna and resonant capacitor,
which greatly reduces the overall cost of the C.label
compared to traditional RFID products.
