An access portal separates an unpaid side of a controlled entry barrier from a paid side. The portal comprises a vestibule connecting the paid and unpaid sides of the controlled entry barrier. A first door separates the vestibule from the unpa id side of the controlled entry barrier and a second door separates the vestibule from the paid side of the controlled entry barrier. A fare collection box is positioned at the unpaid side. A controller is operably connected to the fare collection box. The controller, upon receiving an indication of a collected fare, monitors for a further indication of a collected fare. At the conclusion of the monitoring, the controller cycles the first door, and subsequently, the second door.
