Well the "NexGen" stuff is readable in the Dumbo queue but here's a descript:
Al Lutz described it as:
"Using a system of tiny Radio Frequency ID (RFID) tags embedded in park tickets, key characters on the attractions could interact with each passing vehicle and use personalized information on the riders in each vehicle to embellish the storytelling with personalized references. A Resort guest would fill out a survey form prior to their arrival, and then that information would be downloaded onto the RFID tag embedded in their tickets. Think of this as a much advanced version of the gimmick in Universal’s Hollywood’s now shuttered E.T. attraction where E.T. would bid you farewell by name at the end of the ride, and you’ve got the basic idea. The concept has been branded “Next Generation,” or NextGen for short, in the halls of WDI and they have high hopes for it."
