What do I have to do if I make several trips on the same day?
The rule is simply: Check-In must be active when travelling, and stopped when not travelling.
The app will sell and updates tickets as you travel. The number of check-in/check-out has no influence on the final price: the system might group two journey into one ticket if the price is lower.
If you are connecting between train/bus, we recommend keeping Check-In active (max 25-30 minutes).
