You can pay for your Eurail Pass order online with most credit cards or PayPal.
It is not possible to:
Split the payment of your Eurail Pass order between multiple travelers. Example: if you buy multiple Passes for more than 1 person, 1 person has to make the full payment.
Pay in installments. You have to pay the full order amount at once.
