If you notice as soon as you have checked in, you can cancel the accidental check-in free of charge by checking out again within 60 minutes at the same station.
If you only realise after completing your journey and have therefore made an incomplete journey using your debit card, we will apply a correction fee of € 20. After paying this fee, you can contact the OVpay customer service desk by phone to correct this: dial 0900-1433 on working days between 07:00 and 20:00, or on weekends and bank holidays between 10:00 and 16:00 hr. Make sure you have the following details ready: the reference number displayed on your bank statement (NLOV followed by 14 digits) and the total amount deducted. The excess amount will then be refunded within a few days.
A handy tip: if you would like to travel using an e-ticket on your mobile phone, always upload your ticket into the NS app (instead of using a PDF or screen image). This will help prevent the card reader at the pole or gate picking up your mobile wallet NFC and checking you in with your mobile debit card by accident.
