When will your card be reloaded?
Your card will be automatically reloaded when checking in or out. This also happens if you do not have enough credit to pay the boarding fare or journey price. The credit will then fall below €0 and your card will be reloaded immediately with your chosen amount. So you can simply check in, even if there is little or no credit on your card. As soon as you hold your card to a post or gate, your credit will be uploaded. If your journey costs less than the amount with which your card was reloaded, the remaining credit will be returned to your card.
