The RFID chip is only in the paper cups and refillable mugs at the All Stars Sports Resort.
Here's the deal:
You can only use the paper cups for refills for one hour after purchase and only every 5 minutes.
You can use the refillable mugs for 14 days (As soon as this goes Disney wide then it will be changed to a length of stay time frame I'm sure) and you can only refill them every 5 minutes.
Disney has apparently signed short term "testing" contracts with a soft drink machine vendor that will allow them to "beta test" the idea in All Stars Sports. Then they will probably sign another contract to have these put in all of the resorts. So far the only negativity they have gotten have been from people who were cheating the system before. Personally I cannot wait to see the look on the person's face that is trying to fill up a one gallon milk jug with a soft drink and cannot do it. :ROFLOL: Yes, actually I have seen this very thing happen.
