IT acutlaly doesn't look all that much fastert o me - at least as depicted inhe video - but I'm all for the idea of improved scanning. Certainly there is great room to improve this even further in the future.
I've long been thinkig FRID tags could be used all over WDW to improve several things.
Just two days ago, DH and I were eating at a restaurant which has one of the new video soda machines. They allow you to pick almost any soft drink and add in side flavors; like Diet Coke plus raspberry (or orange, grape, lemon). You can even pick non-carbonated options. (in theory, the choices are endless)
I said WDW should have them. DH intially thought they would slow things down at WDW and would be a bad idea - until we considered the potentital of RFID tags (which is already being tried with refillable mugs). With RFID - and the new soda machines (or custom ones for WDW)- each guest could create a 'custom' beverage or two, perhaps even naming it or tying into characters. Then when you refill your mug - your custom drink would come up as the first choice: "Princess Suzie's raspberry soda", or "Dad's custom coffee blast".
I think the RFID tags have SO much potential. Clearly they can be interactive all over the park.
