Imagine visiting a Disney amusement park with no entry turnstiles. Cash? Passé, as visitors would wear rubber bracelets encoded with credit card information, snapping up corn dogs and ‘Mickey Mouse’ ears with a tap of the wrist. Now stop fantasizing … this may soon be the new reality.

Disney’s new ‘Magic Band’ is a smart, disposable bracelet that is coded with admission privileges. No more cards or badges; this thing is all wireless. The electronic bracelets will also likely be used to track guests and to build loyalty … not to mention sales. So far no timeline for introduction of the new device has been announced. (And you thought ‘The Mouse’ was all-ears before.)
