The "red card" at Disneyland (and Walt Disney World) is a small, red, lanyard-sized card used by Cast Members to accurately measure attraction wait times. When a Guest reaches the entrance of a line, a Cast Member may hand them this card and ask them to carry it until they reach the "boarding" point of the ride. Once the Guest reaches the front of the line, they hand the card to the loading Cast Member. The card is embedded with a sensor (or scanned manually) that records exactly how long it took for that specific card to travel from the entrance to the ride vehicle. This data is then used to update the "Standby Wait Time" displayed on the signs and in the Disney Genie/My Disney Experience app. In 2026, while many queues use automated Bluetooth "beacons" to track wait times, the physical red card is still used as a "verification tool" to ensure the digital systems are calibrated correctly. Being chosen to carry the red card is often considered a small "badge of honor" by Disney enthusiasts.
