Akbil was an integrated electronic ticket system used for fare payment on public transport in Istanbul, Turkey, and was first issued in 1995.

[1] It was valid for boarding buses, funiculars, LRT, metro, commuter trains, ferryboats and trams operated by the Metropolitan Municipality.

Unlike payment by cash, the Akbil allowed a passenger to transfer service within the transportation network under some defined conditions.

[citation needed] The Akbil device was touched to the reader at the faregate to gain access for boarding or on the vehicle to ride.

Alternatively, they could be loaded at special purpose machines, newsstands or small shops which offered this service.
