What would prevent an off site place to collect the signal from cards and steal it? Sure you have to get really close, but it's still possible.
You're getting different kinds of RFID confused. With the RFID tags utilized here, if somebody got so close as to be able to read your information with a RFID reader, that individual would most likely be arrested for attempted assault/molestation before they'd ever be able to get to use your park id..lol. :ROFLOL: This technology is no different than what most companies use to lock their doors, where the card basically has to basically touch the reader for it to be read. Nobody's going to get that close to anybody just to steal a disney park ticket!
