Make sure to check-in before starting your public transport journey!
Once checked-in, you can travel anywhere within the area of validity of the FAIRTIQ region (click on your region to know more about the area of validity).
If you run into a ticket inspector, just click on "display ticket".
However, be careful: You are responsible to make sure that the trip has correctly been started before boarding the vehicle. If FAIRTIQ has not been correctly activated, you DO NOT OWN a valid ticket.
