Carnival said on Tuesday that it wants to transform cruise ships into “smart cities at sea,” introducing an “Ocean Medallion” at the Consumer Electronics Show (CES) 2017 in Las Vegas to personalize each guest’s experience.
The medallion is able to track each passenger’s activity on the cruise ship, learning their favorite wines, meals, and activities. Carnival can also offer appropriate suggestions to passengers and track children’s movements on the ship
