Do I have to check in for the train?
'Check-in' is borrowed from English. 'Devo' is DE-vo — stress on first syllable.
When you have booked a train ticket and are unsure whether any pre-boarding procedure is required.
'Devo fare' (do I have to do) uses 'dovere' for obligation. Unlike airlines, Italian trains do not require check-in. You simply board with your ticket (paper or digital). However, you must have your ticket ready to show the inspector (controllore) on board.
Posso mostrare il biglietto sul telefono?

Il controllore controlla ogni biglietto?
Does the inspector check every ticket?
Yes — train inspections are thorough in Italy
Italian train tickets bought online are valid as digital files (PDF or in the app). The QR code (codice QR) is scanned by inspectors. Fines for travelling without a valid ticket (evasione) are substantial — typically €200 minimum. Even if the inspector doesn't come, always have a valid ticket.
