What a pity that you lost 10 euro by checking out instead of checking in.
There are two things that can happen:
At check-out poles: You try to check out on arrival. Because you have not yet checked in, the system sees this as check in. If you realise this quickly enough, then you can simply check out again. If you do not check out, this will be seen as a missed check out. You can the ask for a refund via Mijn NS or, if you do not have a Mijn NS account, via the online form.
At gates: You check out, resulting in a check out. However, the system blocks the missed check in, which makes it impossible to request a refund via Mijn NS. A refund can only be requested via NS Customer Service
The fastest way to get a refund is to call our customer service on 030 - 751 51 55, or by sending a message via Twitter, Facebook or Chat. You may also send me a private message, if you do please mention your name, address, postcode, OV-Chipcardnumber and your IBAN bank account number.
