I’ve heard of radio tracking devices on cars that monitor my location at all times. Is that RFID?
Basic RFID tags only transmit identifiers in fairly close proximity to reading devices, and have no awareness of their geographical location in a global sense. More sophisticated and expensive devices, particularly those equipped with GPS (global positioning system) technology, are capable of providing continuous and fairly precise geographical data. RFID is a rudimentary wireless device; that is what makes it inexpensive and easy to deploy on a widespread basis.
