Just back from the world and wanted to add my two cents. Touch to enter in the new turnstyle free lanes really was not any faster than using the old regular ticket media. After tapping the ticket to the Mickey head it can take anywhere from 2 to 5 seconds for it to turn green. (I counted, and it did vary quite a bit each day). Only then can you put your finger on the biometric reader (which was pretty quick, probably a second or two). Entering the park, as a result, seemed to actually take a bit longer.
Also, on several occasions, even my wife commented (who is a Disney fan but knows little about nextgen, rfid, etc.) how we could have walked right in without tapping our tickets, as CMs had been interacting with other guests and really didn't even pay attention to us. I still believe this is going to be a huge problem for them, especially with large groups, international guests, or others not familiar with the system. And that all sounds great to those looking to get away with something, but it certainly won't be pleasant when guests try to use Fastpass, and the system doesn't recognize your 4 year old or Grandma as being in the park since their tickets didn't register properly up front.
Finally, since stayed off property, we couldn't use the touch to pay system, but for most credit card transactions we were asked by CM's to swipe on the new devices. The major problem with these being that you can only swipe one way (mag strip face up), which requires multiple swipes if you aren't familiar with the system, as well as only being able to swipe when the CM "activates" the device. Compare this to shopping at a place like Target or your local grocery store, where you can usually swipe with the mag strip facing any direction, and at any point during the transaction (even while things are still ringing up). And the little readers are kind of small, so in many cases after the CM would say you could swipe, they'd have to reach down and hold them in place so they didn't tip over.
Overall, I wasn't very impressed.
