Istanbulkart is a contactless smart card for fare payment on public transport in Istanbul, Turkey.

[1][2][3] The Istanbulkart is valid for boarding buses, funiculars, LRT, subway, commuter trains, ferryboats and trams operated by the Metropolitan Municipality and private companies.

To pay the fare, the smart card is brought into close proximity, up to 8 cm (3.1 in), with a contactless reader during boarding of the transportation vehicle or at the toll gates of the station.

The personalized type of the smart card can also be used in a more general form for admission to an event or establishment or for municipality provided social welfare purposes.

[3] Due to the outbreak of the COVID-19 pandemic, since 2021, all passengers using an Istanbulkart are required to pair it with their HES (Hayat Eve Sığar, literally "Life Fits into Home") code, a public health tracking system.
