South Korea is one of the most card-friendly countries in the world.
In most restaurants, hotels, and stores, you can pay with international credit or debit cards without problems.
However, knowing when to use cash and how to avoid foreign transaction fees can save you money.
Can You Use Credit Cards in South Korea?
Yes — Visa and Mastercard are widely accepted.
American Express is accepted in major hotels and department stores but may not work in smaller shops.
Contactless payments (Apple Pay, Samsung Pay) are also increasingly common.
Do You Need Cash?
You may need small amounts of cash for:
- Street food vendors
- Traditional markets
- Small local restaurants
- Transportation cards (T-money top-ups)
Most travelers carry $50–$150 worth of Korean won.
Pro Tip: While T-money top-ups require cash, you can avoid the hassle by pre-ordering your T-money or NAMANE Card on Trip.com. Pick it up instantly at Incheon.

Should You Exchange Money Before Arrival?
Airport exchange rates are usually worse.
Using a travel-friendly debit card often provides better rates.
How to Avoid Foreign Transaction Fees
Many banks charge:
- 2–3% foreign transaction fee
- ATM withdrawal fees
Using a multi-currency account or travel card can reduce these costs.
Some travelers prefer using a multi-currency account that offers competitive exchange rates and lower international fees. This can help reduce hidden costs when paying in Korean won.
Mobile Payments in Korea
KakaoPay and Naver Pay are popular locally, but they typically require Korean bank accounts.
Tourists mostly rely on international cards.
The Best Alternative for Tourists: Since local mobile apps can be tricky to set up, the NAMANE Card is highly recommended. It’s a customizable prepaid card you can manage via an app. Book your voucher on Trip.com to skip the payment steps at the kiosk!
