As part of the change, paper tickets and farecards also went out with the old year, apart from the possibility of buying a ticket from the driver in a pinch; mechanical and electronic ticket validating machines will be uninstalled in the first days of the New Year, the city government said.

In the case of most adults, free ridership of buses, trams and trolleybuses requires that they be registered in the Population Register as Tallinn residents. After that, they must purchase a personalized farecard - the "ühiskaart" - and validate each trip as they enter the vehicle. The farecard is only good when accompanied by an identity document.



In addition, all pupils and students age 19 and under who are listed in the Population Register as residing in Estonia enjoy free public transport in Tallinn.



The personalized farecard is good on Harju County public transport routes, which are integrated with Tallinn's.



A total of 150,000 farecards had been purchased according to last count - as of late December.
