La tarjeta de embarque o "pase de abordaje" es un documento empleado por las compañías de transporte de pasajeros, tanto aéreas como marítimas, para permitir el acceso al vehículo transportador.

A boarding pass is a document provided by an airline during check-in, giving a passenger permission to board the airplane for a particular flight. As a minimum, it identifies the passenger, the flight number, and the date and scheduled time for departure. In some cases, flyers can check in online and print the boarding passes themselves. A boarding pass may be required for a passenger to enter a secure area of an airport.
