Korea · the click
Seoul stays up late to see whether you will too.
The city falls into place the moment the gate lets you through. Palaces, the Hangang, a grandmother in a sun visor: none of it works while you are still arguing with a ticket machine. T-money first, opinions later.
Day one starts with a card
First-time visitors collect palaces before they have a way home, and end up worn out on Line 2. Buy the card, then see two neighborhoods and the river. Seoul first days is the short version of the trip; this page covers the tap itself.
In some years there are visitor cards, with deposits and expiry rules that change. We will not freeze a blog’s figure into your bag. The issuer’s page and the airport’s page for the week you fly are the ones to trust.
Get a transit card on day one. Then the city can begin to introduce itself.
The KTX south is a separate service; check the operator for trains to Busan. The free Korea kit lays out a Seoul to Busan trip you can finish, and it works offline.
Decide
T-money or a Korea-wide pass?
Get a transit card on day one: T-money, or the visitor card the machines sell, topped up when needed. A long-distance ticket south is a separate purchase and does not make the metro free. We will not invent a card balance in won or a KTX fare; the operator publishes fares. For orientation, see visitkorea.or.kr.
At the airport, or at the first station?
At whichever machine you reach while you can still think clearly. Don’t try to fix a wallet app during a rush-hour transfer. Get the plastic card first. Convenience stores often top it up. We leave out which counters are open on a Sunday.
Does it work in Busan?
Often, on city transit. The KTX still needs its own ticket. We will not print a compatibility chart that goes out of date. If a gate refuses the card, the local issuer has the answer. Busan is sea air at the end of the line, not a footnote to the metro.
Cash or card on the bus?
The card is what makes the city work. Drivers are not a currency exchange. Tap, sit down, and give your seat to someone older when the moment calls for it. Courtesy matters here too.
How to take it
Tap in, then see two neighborhoods
Getting your first card
Buy it from a machine, a convenience store or the visitor desk, depending on what is offered this year. Bring your passport in case they ask. We do not invent the deposit.
Stay near a line that joins your two neighborhoods
Jongno if palaces fill your mornings, Hongdae or Seongsu for students and workshops. Read Seoul.
Take long trains only when the week has room
Busan is a chapter of its own, not a trophy added on night one. See Korea transit for how the route fits together.
Then go
Sunday lunch with Korean families is busy for good reason. Chuseok and Seollal empty the capital toward hometowns, and you walk through a city that has lent itself to its families. Be a guest, and top up the card when the reader asks.
