Hi,
from 31 Jan 2023 NS the national operator in the Netherlands will have the possibility to travel with Credit Cards with the train only using the credit card as a ticket like tap and go in cities like London for the underground.
If you are travelling with an Interrail or Eurail Pass than you have to stop on your phone the possibility to use NFC if you have a Credit or Debit Card on your smart phone, because the ticket barriers at the station will register your credit card and not the QR-Code of your mobile Interrail/Eurail Pass.
Maybe the Eurail Team can do something that using the Rail Planner App the payment service is turn off like when using NS app.
Mostly this problem will have iPhone users.
