'Touch to Pay' lets guests charge to their Walt Disney World Resort room by simply touching a Key to the World RFID card or MagicBand. So far this has been restricted to payments made at fixed register locations, which includes shops, kiosks, and quick service restaurants.
Disney is about the begin testing mobile 'Touch to Pay' which will allow guests to make 'Touch to Pay' payments at Table Service restaurants and other mobile locations, such as boat rentals and other recreation activities. Beginning in the last week of May, Disney's Contemporary Resort will allow 'Touch to Pay' payments at the The Wave restaurant and at outdoor recreation locations. Guests will be able to touch their RFID Key to the World card (and later the MagicBand) to the Cast Members mobile device, enter a pin number, and complete the transaction.
As well as handling payments, the system allows servers to access any Disney Dining Plan information, which helps the server advise the guest on the dining entitlements that are available.
