How to Use the İstanbulkart and Istanbul Public Transport in 2026
The İstanbulkart, sorted out for 2026
The İstanbulkart is the rechargeable transit card that works on every metro, tram, ferry, bus, funicular, and cable car in the city. As of 2026, a single ride is 27 lira if you've registered the card and 40 lira if you haven't, and the same card gets you transfers at a reduced rate within two hours. That last part is the bit nobody mentions and it's the reason you want the card instead of paying contactless with your bank card.
Here's the thing worth knowing first: you can pay with a contactless bank card directly at most turnstiles now, no İstanbulkart needed. The catch is that contactless bank card fares are 40 lira flat per ride with no transfer discount, so a single journey involving a metro plus a tram plus a ferry costs you 120 lira instead of about 50 with the İstanbulkart. For a three-day visit with normal sightseeing, the card pays for itself in the first afternoon.
Where to buy one
You'll find İstanbulkart vending machines (yellow, marked "İstanbulkart") at every metro station, tram stop, and major ferry pier including both airports. The card itself costs 130 lira as a one-time purchase and is non-refundable. Buy it with cash or card at the machine, then load credit on the same screen. We'd put 200 lira on it to start. You can top it up later at any station or through the BiTaksi-owned İstanbulkart app on your phone, which lets you add credit with a Turkish bank card (visitors usually top up at the machines instead).
The machines have an English option. Tap the flag, then "Buy new card," then "Load credit," then pay. The whole thing takes under two minutes.
The airport run
From IST (the new Istanbul Airport on the European side), the M11 metro runs from the airport to Gayrettepe, where you transfer to the M2 line for Taksim, Şişhane (for Galata), or Vezneciler (for Sultanahmet area). Total journey: around 70-90 minutes depending on transfers. Total cost with İstanbulkart: about 54 lira. Without the card, paying contactless: 80 lira.
From SAW (Sabiha Gökçen on the Asian side), the M4 metro connects to Kadıköy where you can take the ferry to Eminönü or Karaköy. Around 90 minutes, around 54 lira with the card.
Buy the İstanbulkart at the airport metro entrance before your first ride. The machines are right there.
Can two people use one card?
Yes, and this is the answer the official sites bury. Tap the card, then hand it back over the turnstile or through the gate to your travel partner. The second tap within a short window registers as a separate paid ride at the same reduced fare. Works on metros, trams, and ferries. Two adults sharing one card is fine and the system is designed for it. The only place it gets awkward is buses with rear-door tap readers, where the geometry doesn't really work, but front-door tapping is easy.
The Moovit shortcut
Download Moovit before you arrive. It handles Istanbul transit better than Google Maps for our money, especially for ferry schedules and the bus network. Type your destination, pick the route, and it tells you which line, which transfer, and how long. Pair it with the İstanbulkart and you can move around the city like you live here.
One last thing
Ferries are the best deal in Istanbul transit. The Eminönü-Kadıköy crossing is 27 lira with the card and gives you the same Bosphorus view as a 40-dollar tourist cruise. Take it at sunset. That's the move.
