What happens if I leave the perimeter of validity of FAIRTIQ

If you leave the perimeter of validity of FAIRTIQ (I.e. travel in Germany), you do not own a valid ticket anymore and you risk a fine.

• Area of validity: Switzerland and Liechtenstein
  
• Area of validity: Göttingen
• Area of validity: Vorarlberg
• Area of validity: Linz

So don't forgett to check-out before you leave the area of validity and ensure to buy a valid ticket for the rest of your trip.
