With the Tripkey Mobility Card, you can access public transport in the Netherlands and make use of the OV-bikes. Before traveling, you have to register your card in the Student Mobility App, connect a valid payment method and pick up the travel products at an OV-device. To do so, follow the instructions on your leaflet. After picking up the travel products at an NS or OV-chipkaart device, you are ready to travel. From then on, the app will show you your travel transactions and travel costs. We'll charge your bank account or credit card on a regular basis.
