One of the many responsibilities that the deckhands have is the collection of tickets. When you activate a ticket on the App it has moving animation, date and time the ticket was activated and the origin and destination terminals, those items plus your tapping of the screen that changes colors verifies you have a real App ticket. The deckhand is not responsible for showing you how the App works and should never handle your phone. If you cannot present a valid active App ticket you must purchase a paper ticket and contact our customer service department for help.
