Children and adults can use the FAIRTIQ app to buy tickets.
Children (age: from school enrolment to 14 years) and adults can use the FAIRTIQ app to buy tickets. FAIRTIQ automatically recognises whether the children's fare still applies or whether the adult fare already applies based on the date of birth entered during registration.
In principle, only the person who is registered in the app can buy a ticket for themselves to start their journey immediately.
