You can pay with them in the parks (no fishing around for cash or your credit card), it links to your Disney accounts, you can use them as a ticket to get into the parks and it functions as your door key at Disney hotels and cruise ships.

It’s insane. There’s long range detectors all over the parks that can pick up the general amount of people in that area of the park for analytics purposes. For example, in the Star Wars area of the park, your MagicBand is detected behind the scenes and your performance on the Millennium Falcon is saved, and cast members can comment on it at point-of-sale terminals (“Hey! I heard you crashed the Falcon!”).
