South Korea is widely known for its advanced digital infrastructure, and credit cards are accepted in most hotels, restaurants and stores. However, travellers may still need cash in smaller shops, local markets, street food stalls and some rural areas.
International visitors should also inform their banks before travelling to avoid card payment issues overseas. Currency exchange services are easily available in airports and major tourist districts such as Myeongdong in Seoul. Carrying a mix of cards and some local currency can make travel more convenient across the country.
