01.The Remaining Cash Necessities in Seoul
Every convenience chain, trendy cafe, and department store in Seoul accepts international credit cards.
However, public transit card recharge machines inside subway stations accept only Korean Won cash notes.
Arriving without physical Won can leave travelers stranded before boarding their initial subway train.
Exchange or withdraw roughly 30,000 to 50,000 KRW upon arrival at Incheon or Gimpo Airport to load your subway card.
