Disney Magic Bands are a part of the new My Disney Experience technology which is currently being implemented in Walt Disney World.  At this time, Magic Bands are still in the beta testing phase, and only guests staying at select Walt Disney World resorts have been invited to test.  As this technology is continuing to change, it is important to note that this tutorial was written on September 13, 2013 and may quickly become outdated.

Magic Bands are soft, rubber wrist bands that contain an RFID chip.  Guests will be able to have their credit card, resort key, park tickets, dining plan, FastPass+, and Photopass+ package linked to their Magic Band.  So instead of swiping your key card with a magnetic strip, you'd simply tap your wrist band against a sensor to enter the park or FastPass queue or pay for a meal.  You are not required to use the Magic Bands and may instead opt to use a traditional RFID-enabled Key to the World card (however, during testing, anyone who wants to use FP+ must use the bands).

These bands are waterproof and can be worn in the pool or at the water parks.  The band only comes in one size.  However, there is a portion of it which is removable so that it is a better fit for smaller wrists.  These bands are intended to be brought back to Walt Disney World for years and have a 3-year battery life.
