OVpay is the new way to check in and out of public transport in the Netherlands
From now on you can also check in and out at the RET with your debit card, credit card or mobile device.
All the fares you spent travelling on a given day will be deducted in one go from your account the following day. The debit always shows a payment reference starting with NLOV followed by 14 digits and letters. More information: https://reisoverzicht.ovpay.nl/reisoverzicht or the OVpay app in the app stores.
