It would be impossible to track your flyers via radio frequency identification. RFID is a short-range identification and tracking technology. Tags can be read from a distance of only a few inches to a few thousand yards. There are active tags that combine RFID and GPS functions, but these are expensive and bulky (a little larger than a cell phone), so they would be inappropriate for use on flyers.
