Antipater writes "Disney parks and resorts have long had a system that combined your room key, credit card, and park ticket into a single card. Now, they're taking it a step further by turning the card into an RFID wristband (called a 'MagicBand'), tracking you, and personalizing your park experience, targeted-ad style. 'Imagine booking guaranteed ride times for your favorite shows and attractions even before setting foot in the park,' wrote Tom Staggs, chairman of Walt Disney Parks and Resorts, in a blog posting on Monday. 'With MyMagic+, guests will be able to do that and more, enabling them to spend more time together and creating an experience that's better for everyone.' Disney does go on to talk about all the things you can opt out of if you have privacy concerns, and the whole system seems to be voluntary or even premium." With a theme park, at least, you can also choose to avoid the place entirely; that makes it, however creepy, a bit different from compulsory education settings, or mandatory car tracking.
