  • Credit cards
  • Debit cards
  • Mobile payments
  • T-money transportation cards

Even small purchases at convenience stores, cafés, and restaurants are commonly paid for by card.

Good News for Tourists

You usually won't need to carry a large amount of cash during your trip.

Can Foreign Credit Cards Be Used in Korea?

In most cases, yes.

Major international cards are widely accepted throughout South Korea.

Card Type Accepted?
Visa ★★★★★ Yes
Mastercard ★★★★★ Yes
American Express ★★★★☆ Usually
JCB ★★★★☆ Usually
UnionPay ★★★★☆ Widely Accepted

Hotels, department stores, cafés, supermarkets, restaurants, pharmacies, and convenience stores generally accept international credit cards.

Where Can You Pay by Card?

Location Card Accepted
Hotels ✅ Almost Always
Restaurants ✅ Yes
Cafés ✅ Yes
Convenience Stores ✅ Yes
Department Stores ✅ Yes
Supermarkets ✅ Yes
Subway Ticket Machines ⚠ Depends on Machine
Traditional Markets ⚠ Sometimes Cash Preferred
Street Food Vendors ⚠ Cash Recommended

Should You Carry Cash?

Although cards are accepted almost everywhere, carrying a small amount of cash is still a smart idea.

Cash is useful for:

  • Traditional markets
  • Street food stalls
  • Small local shops
  • Coin lockers
  • Some transportation card top-ups
Recommended Amount

Most tourists will find that carrying around 50,000–100,000 KRW in cash is sufficient for a typical day, while using a credit card for most other purchases.

Where Should You Exchange Money?

There are several convenient places to exchange foreign currency in Korea.

Location Recommendation
Incheon Airport Convenient but exchange rates may be less favorable.
Myeongdong Exchange Centers Often offer some of the best exchange rates for tourists.
Banks Reliable and secure.
Currency Exchange Booths Common in major tourist areas.

If possible, compare exchange rates before exchanging a large amount of money.

Should You Exchange Everything at the Airport?

Not necessarily.

Many experienced travelers exchange only a small amount of cash at the airport for immediate expenses such as transportation, snacks, or a T-money card.

They then exchange additional money later in central Seoul, where exchange rates are often more competitive.

Money-Saving Tip

Avoid exchanging all of your travel budget at the airport. Exchanging only what you need for the first day can help you get a better overall exchange rate.
