You are 99% correct. RFID is a PASSSIVE device that only activates when near enough to the RFID transmitters, i.e. the tapstiles you hold the MB up to when you enter the park, payment points, fast pass tapstiles, etc. However, there are low power transmitters (1.175 milliwatts if I remember correctly) in the MBs that are used for triggering ride photos, crowd tracking, etc. in the bands too. Since they are certified only in the U.S. they can't legally ship them to other countries where they have not been certified by that country's equivalent of our Federal Communications Commission.[/QUOT
