FAQ
Reader questions
Is it better to exchange currency before arriving in Seoul or use local ATMs?
Using ATMs in Seoul, especially at major banks or convenience stores, usually offers better rates and lower fees than pre-exchanging large amounts abroad.
Do smaller shops and street vendors accept foreign credit cards?
Many small shops and street stalls prefer cash or mobile payments; carrying some Won ensures you can make purchases without issues.
Can I use my Korean Won-denominated credit card without foreign transaction fees?
If your card is issued in your home country and charges foreign transaction fees, using it in Seoul will typically add a percentage to each purchase or ATM withdrawal.
