Every city seems to have its own answer to a simple question: how do you actually pay to get on a bus or train? Some hand you a paper ticket, some want a rechargeable local card, some just take your bank card at the gate. Rather than memorising each city's system in advance, it helps to have one method for figuring it out quickly on arrival — this guide walks through the four payment types you'll meet and how to work out which one a given city expects.
The four payment types you'll encounter
1. Cash
Still common for buying a single ticket from a machine or a driver in many cities, though a shrinking number let you pay a bus driver directly (London's buses, for instance, are card-only). Cash is useful as a fallback when a machine won't take foreign cards or an app won't load, so it's worth carrying some local small notes and coins even in cities that are mostly cashless for transport.
2. A local transit card
A rechargeable card specific to that city's network — Oyster in London, Navigo Easy in Paris, Suica in Tokyo, Octopus in Hong Kong, the Tarjeta Multi in Madrid. You typically buy the card itself for a small fee, then load it with individual trips or a pass. This is the most common model worldwide and usually the safest default assumption for a city you haven't researched yet.
3. A contactless bank card or phone wallet
In a growing number of cities (London, New York, Sydney, Singapore and others), you can simply tap the contactless bank card or phone wallet you already own directly at the gate, with fares and caps calculated automatically. See our contactless transit payments around the world guide for which cities currently support this and which don't.
4. A city or transit app
Many networks now sell digital tickets through an official app — Berlin's BVG app, Prague's PID Lítačka, Munich's MVV app — which is often the fastest option since it skips finding a working machine and, in systems with paper validation, skips the separate stamping step too.
A simple method: work it out in this order
- Check whether contactless bank card tapping is supported. If it is (and reliably so, not a partial pilot), this is usually the easiest option for a short visit — nothing to buy in advance, and fares are calculated for you.
- If not, check for an official app. Downloading the local transit authority's app before you travel, or on arrival using station wifi, often lets you buy and validate tickets from your phone without hunting for cash or a working machine.
- Otherwise, budget time to buy a local card on arrival. Look up whether the city expects a rechargeable card (most of Europe and Asia) or sells straightforward paper tickets, and where to buy one — often at the airport or the first station you reach.
- Always carry some local cash as a backup, regardless of which method you plan to use, in case a machine, app or reader doesn't cooperate.
Signs a city still uses paper tickets or time-based fares
Cities without ticket gates — Berlin, Munich, Vienna and Prague are good examples — often rely on an honesty system with random inspections rather than barriers, which changes what "paying properly" means: you need a ticket that's been validated (stamped or app-purchased), not just a ticket in your pocket. Prague goes a step further with time-based fares, where your ticket buys you a block of minutes rather than a single trip or zone — worth understanding before you board, since the logic is genuinely different from a distance- or zone-based system. Our guide to understanding fare zones covers how zone-based pricing works more generally.
Common mistakes visitors make
- Assuming contactless will just work everywhere. It's spreading fast but is still far from universal — check before you land rather than discovering at the gate that it isn't supported.
- Boarding without validating a paper ticket in a gateless system. An unstamped ticket usually counts as no ticket at all if you're checked, and the fine is a fixed penalty, not a discounted top-up.
- Not budgeting for an airport supplement. Several cities (Madrid, Berlin's zone C, Munich's outer zones) charge extra or need a different ticket specifically for airport travel, on top of the standard city fare.
- Buying a weekly pass on the wrong day. Some weekly tickets run Monday to Sunday regardless of when you buy them, so a pass bought on a Friday might only cover two days rather than a full week forward.
Frequently asked questions
What's the single safest payment method to assume before researching a specific city?
A local rechargeable transit card is still the most common model worldwide, so it's a reasonable default assumption. But it only takes a couple of minutes to check the specific city's official transit site before you travel, which is worth doing since contactless or app-based payment can save you the hassle of buying a card at all.
Should I buy a transit card or ticket before I arrive, or on landing?
Some cities (Barcelona's Hola Barcelona card, for example) let you buy online in advance and collect on arrival, which can save time. In most cities it's just as easy to buy on landing at the airport station or first stop, so it usually isn't essential to arrange in advance unless you want the certainty.
Do transit apps work without a local SIM card?
Most official transit apps can be downloaded and used to purchase tickets over wifi (at your hotel or the airport) or, if your phone supports it, over roaming data — you generally don't need a local SIM specifically for the app to function, though check the app's requirements beforehand if you'll have no connectivity at all on arrival.
Is it ever cheaper to just take taxis or ride-hailing instead of figuring out transit tickets?
For very short stays with minimal travel, it can be, but public transport is almost always significantly cheaper per trip in major cities once you're making more than one or two journeys a day, and it's often faster in dense city centres with heavy road traffic.
