New iWatch Uses

An interesting article in Business Insider wonders if Apple's iWatch could possibly share some features that Disney has incorporated in their theme park MagicBands.  The key might just be the radio frequency built into these consumer friendly wearables.  "Want to buy food while you're at the park? Just scan your wristband and enter a PIN. Tired of scrambling for your hotel key? Simply tap the wristband to your door. The wristband is connected to a credit card and is capable of replacing your wallet, keys, and theme park tickets throughout Disney's sprawling campus. It essentially acts as a digital ID that you wear around your wrist."  Could Apple be emulating these features in their own design?  It certainly opens up new possibilities for usefulness for the future device.
