Fast pass on demand will be available at kiosks in the park. Not everyone is issued tickets for admittance. Disney has already announced that CM current "front gate" cards are being reused again next year. This pass works to get in and no other ticket is issued. To my knowledge there is no RFID in this pass at this time. Some of these cards are several years old and predate this technology. Paper tickets will still exist for a long while I think there will be an option of either media given.
Not everything is going to be virtual because many guests do not have technology to do it. Many people still do not have smart phones.
Supposedly RFID is coming in DEC to MK main gate.(The Dec date comes from what I was told while there are work last night)
It was on Channel 6 news that its starting roll out with annual passholders. I cannot find the link to the story right now.
