Can I use T-money in Busan or Jeju?

Answer status
YES, NATIONWIDE

Quick answer

Yes. A T-money card bought in Seoul works on subways, buses and taxis in Busan and Jeju, so you do not need a new card in each city. One card cannot be shared by several people at once.

What you should know

  • Tmoney says you can ride subways, buses and taxis in Busan and Jeju with a card bought in Seoul.
  • One T-money card cannot be shared by several people at once; use one card per person.
  • Taxis need a card reader, and not every taxi has one.

What you need

  • โ€ขOne card per traveler
  • โ€ขCash to top up
