an overview of RFID tags

Jeffrey R. Harrow, writer of the very excellent “The Harrow Technology Report “, has written this article on the current state of  "Radio Frequency Identification Tags" (RFID Tags). I've been trying to keep up to date with RFID over the past couple of years, as this technology obviously has the potential to dramatically impact the way we do business and live over the next decade. There are so many scenarios where this makes sense, that the privacy implications seem, to me at least, to be trivial.
