National shared transit card · Concept
One card for every road in Türkiye.
YOLDAŞ means travel companion. One card, one balance and one shared network on every bus, metro, tram and ferry in all 81 provinces.
The problem
One trip, three cards.
Travel from Ankara to İstanbul to İzmir and you meet three cards, three apps and three balances. None of them talk to each other.
Illustrative balances. Money left on one city card cannot be used in the next city.
Lost time
Find a kiosk, buy a card, add money, learn the system. In every new city.
Stuck money
The balance on one card usually cannot be used in another city. It just sits there.
Confusion
Different apps, different payment rules and different fares for the same traveller.
The idea
Think of it like a SIM card.
Wherever you travel in Türkiye, your SIM keeps working. YOLDAŞ does the same for public transport.

Slogan from the project. YOLDAŞ is a concept design, not an official product.

The integration layer
One layer above every city.
YOLDAŞ does not replace local systems. Each city keeps its own validators, fares and ferries. YOLDAŞ sits on top and records every journey.

Making it real
What makes YOLDAŞ smarter.
Phone as a card
NFC phones and smartwatches work like the physical card.
Discounts travel too
Student, teacher and senior fares work in every city. A student from Ankara pays the student fare in İzmir.
Visitor pass
A tourist card for foreign visitors, sold at airports and hotels.
Safe balance
The balance is tied to your account. Lose the card, keep the money.
Mini game
Tap & Go
Cross five cities with one card. Tap each validator when the needle is inside the orange zone. Miss and the reader asks you to try again, and every second costs you.
