What Is An RFID Tag?
Radio-Frequency IdentificationAutomatic Identification method that relies
on storing and remotely retrieving data using devices called RFID tags or transponders.
The RFID tag is an object that can be applied to or put into a product, animal, or person for the purpose of identification using radio waves.

What Is An RFID Tag?
Most RFID tags contain at least two parts. One is an integrated circuit for storing and
processing information, modulating and demodulating a (RF) signal and can also be used for other specialized functions.
The second is an antenna for receiving and transmitting the signal.
Two types of tags: Passive and Active

Privacy
How would you like it if, for instance, one day you realized your underwear was reporting on your whereabouts? — California State Senator Debra Bowen, at a 2003 hearing
You never really can tell where an RFID tag is because it can put inside of something and not visible to the eye.
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 purposes unrelated to their supply chain inventory functions.
