 Flat fare journeys are processed by a validating machine on the right of the entrance door of the bus.When the fare for the journey is to be determined by the number of stages to be travelled, the validating machine on the left of the entrance door should be used and the driver informed of the destination to avoid overdeduction from the cash balance on the card.Nitelink buses charge a €6.60 flat fare (€4.50 on Leap)  regardless of the distance travelled.
