Transit cards simplify many subway and local-bus fares, but some intercity tickets need separate booking.
What a transit card is useful for
A reloadable transportation card reduces the need to buy separate fares for many subways and local buses. It is useful across a multi-city trip when supported by the local operator.
What it does not replace
It does not automatically reserve KTX seats, intercity buses, flights or every airport service. Those journeys may require a separate ticket or reservation.
Buying, loading and checking balance
Purchase and top-up locations vary. Confirm accepted payment methods at the machine or counter, keep enough balance for the next journey and check refund rules before leaving Korea.
Transfers and correct tapping
Tap where the local system requires it when entering, exiting or changing vehicles. A missed tap can affect fare calculation or transfer treatment.
Before you act
- Know which legs need separate reservations.
- Check balance before a long day.
- Follow entry and exit tapping signs.

Do not assume so. Accepted payment methods depend on the location and machine.
