Which code do I show on a train?

His pass is in the Rail Planner app. Every train goes on the pass first. Some trains also need a booked seat.

Every train, every time

1Before boarding: Rail Planner, My Trip. Find the train and switch it on, so it is added to his pass.
2On board: My Pass, then Show ticket. That QR code is what the conductor scans.
3Once a day: open Rail Planner with signal or wifi. After 24 hours offline the pass stops working until it reconnects.
Pass QR only

Add the train, show the pass. No booking, no extra cost.

Pass QR + booked seat

Add the train to the pass too, then show both: the pass and the seat ticket.

Not on the pass: buy a ticket
Always carry the passport whose number is on the pass (the real one, not a photo) and a charged phone. His travel days are in the trip app.
