Today, they had the left side of the entrance using the RFID with the pods, the right still used the old turnstiles. It never worked for us. Walked through the security check and they scanned our tickets and got the sticker put on. Going to the "pods", the system turned blue. They had to swipe our tickets again in a iPhone/iPod housed with a scanner to fix them. A bit later I had to run back out to the car for something and didn't scan again. I'm assuming due to re-entry, but not positive. Asked a few questions and they said it was going to be a 2 week test which means it'll be used during the busy holiday next week.
Even though I didn't have a stellar first encounter, I see it as a great move. Even before reading this here, I was telling the family of all the benefits and information Disney could glean, forecast, and even advertise (tie in texting/Disney app with locations). The iOS interface to the database is already there, so the possibilities are endless.
As for security....let security handle it. For those with bags, have the RFID there as they scan the bags. For those without bags, have the "V" shape of pods set up. If it fails, send them to one of the people who would have been handling the turnstiles and now hold an iPhone scanner. If they can't fix it in under a minute, send them to Guest Services. This would get rid of the stroller issues in the turnstiles and still separate those with bags from holding up other people.
The downside is I don't see anything helping with those that can't seem to grasp the concept of putting in your ticket and scanning your finger. This would blow their minds....Also, if the "key to the world" changes to bracelets, this means whoever runs for fast passes will have to carry 5 bracelets instead of 5 cards.
