In Gdansk, you generally cannot buy paper tickets directly from the tram driver once you are on board. The city’s transit authority, ZTM Gdańsk, has transitioned to a more automated system. Instead, you should purchase tickets from the ticket vending machines located at most major tram stops or at various kiosks throughout the city. If you find yourself on a tram without a ticket, the most common 2026 method is to use a mobile payment app like Jakdojade, SkyCash, or mPay, which allows you to buy a digital ticket instantly via your smartphone. Additionally, many newer trams are being equipped with "tap-to-pay" validators that allow you to use a contactless credit or debit card directly, but this is not yet universal across the entire fleet. It is vital to have a validated ticket (either digital or stamped paper) the moment you board, as inspectors are frequent and the fines for "riding black" (without a ticket) are strictly enforced and must often be paid on the spot by tourists.
