"StitchKingdom is reporting that Disney has applied for a patent that could mean the end of the beloved refillable mugs in Disney Parks and Resorts...or at least the end of the free refills...
The new "Self-Service Beverage and Snack Dispensing Using Identity-Based Access Control" system would mean that your Key to the World card " or even potentially your fingerprint " could do more than just get you into the parks; it could determine your fate as to how many refills of that Orange Fanta you can get next time you're at Pop Century's Food Court!
That's right, Disney's proposing using RFID technology to put an end to endless refills " unless you're legitimately paying for them. (Time to throw away those Wilderness Lodge mugs from 1997, maybe? Or at least put them on ebay...)
Of course, in my heart of hearts, I'm hoping this might also be the beginning of automats in Disney World (which would be a.w.e.s.o.m.e.). The patent mentions "snack dispensing" ability, which, I hope, means I can go get a butterfinger cupcake at any time of the night...as long as I have the right magnetic strip to scan, of course..."
Not sure how much validity this has because they just released the new refillable mugs for this year but I think I would be sad if it was....love the refillable mugs
