Planning your first ride in Seoul? Start with one short journey rather than trying to learn the whole network. This guide focuses on a regular physical Tmoney card and everyday subway and city-bus trips, not airport express tickets or unlimited travel passes.

1. Buy the card, then add travel money
Visit Seoul lists convenience stores such as CU, GS25 and 7-Eleven among Tmoney sales locations. Buying a card and loading travel credit are separate steps, so ask whether it already has a balance.
For regular physical Tmoney top-ups, bring Korean-won cash. KTO’s guide also warns that foreign bank cards cannot be tapped directly at subway gates or bus readers. Our suggestion: sort out your card before joining a busy queue.
2. Plan the station, direction and exit
Write down your destination station and the exit closest to where you are going. Before entering, check the line and direction on the station signs. For the subway, tap your transit card at the entrance gate and again when leaving. Keep it accessible until you have passed the exit gate.
Our practical tip: save your destination’s Korean address and a screenshot of the route before leaving your accommodation. If a reader rejects the card, step aside and ask station staff rather than repeatedly tapping or following another person through.
3. On a bus, remember the tap when you get off
For city buses, tap when boarding and when getting off. Seoul’s transfer rules require the exit tap and a qualifying connection within the allowed time; changing vehicles does not make every trip free. Distance and route conditions can affect the fare. We recommend a separate card for each traveler as a simple planning rule, especially when your journey includes the subway.
Before boarding, check the bus number and which direction it is traveling. Our suggestion is to choose an uncomplicated first route, then add transfers once you feel comfortable. Do not build a tight airport connection around this beginner guide.
A small checklist before you go
Have your card, enough balance for the planned journey, a way to add more credit, your destination address and your return route ready. Check current fares, service notices and the final departure for your particular route with the operator. Avoid assuming all lines share one closing time.
