What happens if you forget to check out in the Rejsekort app?
Warnings, Smart check-out and the night rule.
Short answer
If the phone's sensors suggest you have stopped travelling without checking out, you get a warning in the Rejsekort app, provided notifications are switched on. Every night at 04.00, trips started before 22.00 without a check-out are closed and priced automatically, unless there was travel activity just before 04.00. You can also turn on Smart check-out, which sends a notification and checks you out after a 5-minute countdown unless you cancel it. A trip that runs past the maximum travel time for the fare zone is split into two trips for payment.
Why
- You check out only when the whole trip is over, not at each change.
- The phone must stay on during the whole trip.
- Airplane mode can cause an automatic check-out.
Details
Checking out while the trip is still going on counts as misuse under the national travel rules.
Tip
Allow notifications and motion data when you set up the app, so it can remind you to check out.
What may differ
The rules follow the app terms, version 8 from 22 October 2026, and can change with a new version.
Common misconception
Many think the app always checks you out by itself as soon as you get off.
What actually happens
It only checks you out by itself if Smart check-out is on; otherwise open trips are closed at 04.00 at night.
