The main way of paying for Dutch bus and train services is by holding an OV-chip card in front of the card reader at arrival and departure. Learn more about OV-chip cards and how to use them here. If you forget your OV-chip card or you have not purchased one yet, then it is still possible to buy regular tickets (disposable OV-chip cards). For trains this can be done at an NS ticket machine in any station. The machines are easily recognizable by their large size and yellow colour. If you’re travelling by bus, you can buy paper tickets from the driver in cash or with debit card. Please take into account that paper tickets are almost always more expensive than paying for your travel with an OV-chip card.
