On Monday, 10 June, I traveled with friends from Duivendrecht station. I scanned my OV card, as always, assuming I was checked in. Once I reached my destination (Veenendaal West), I checked out, not realizing it had only checked me in at that point (this happened to my friends as well). Later that same day I traveled to Amsterdam Central. When leaving Veenendaal West I was notified that I was already checked in, I assumed I double tapped my card on the machine, since this had happen before, a bit confused I traveled to Amsterdam and checked out on arrival. Therefore I didn't think anything of it, until checking my NS app today and noticing a 20 euro fine.
I request this please be removed, since it was am honest mistake, and not being in the Netherlands long, I didn't even know this could happen. I also don't have the money to pay for this, being an Au Pair. When traveling next time I'll be more observant.
