what is a magic band disneyland

A MagicBand is a wearable tech bracelet that is worn on the wrist, like a watch, and is used to enhance the guest experience at Disneyland. It uses radio-frequency identification (RFID) technology to connect to park tickets or Magic Key Annual Passes to enter parks or Lightning Lanes. Additionally, it can be used to link PhotoPass memories and interact with select nighttime shows, such as World of Color and Fantasmic!, by glowing with color and pulsing with haptic vibrations. MagicBands are not necessary for entry into the park or for using Lightning Lanes, but they can be a fun convenience item to enhance the guest experience. They are also necessary for certain games, such as Bounty Hunting in Batuu. However, they are not supported at Walt Disney World at this time.
