The best way to get Korean won is usually a low-fee debit card at a Global ATM, or a good city exchange booth if you brought cash. Exchange only a small starter amount at the airport, around ₩30,000–₩50,000, then use ATMs or compare rates in the city. When paying by card or withdrawing cash, always choose KRW, not your home currency. That avoids Dynamic Currency Conversion, one of the easiest ways to lose money in Korea.
Korea is card-friendly, but you still need some cash. T-money top-ups, traditional markets, street food, small restaurants and taxi backup are the main reasons.
The goal is not to carry huge stacks of won. The goal is to get enough cash at a fair rate without getting trapped by airport spreads, ATM fees or bad currency-conversion prompts.
What is the best way to get Korean won?
For most travelers, use this order:
Method | Rate | Best for |
|---|---|---|
Global ATM + low-fee debit card | Usually best | Most travelers |
City exchange booth | Good if rates are posted clearly | Cash holders |
Airport exchange | Convenient but usually worse | Small starter cash |
Hotel exchange | Usually poor | Emergency only |
DCC card/ATM conversion | Avoid | Almost never worth it |
The cleanest setup is simple: bring a foreign debit card with low overseas fees, withdraw Korean won from a Global ATM, and use your credit card for most purchases.
Should you exchange money at the airport?
Yes, but only a small amount.
Airport exchange counters are convenient when you first land, but they are rarely the best-rate option. Use them for starter cash only — enough for a T-money top-up, taxi backup or a small emergency.
A good starter amount is ₩30,000–₩50,000 per traveler.
Do not exchange your whole trip budget at the airport unless you have checked the rate and are comfortable with the spread.
How do you use ATMs in Korea?
Look for an ATM marked:
Global ATM
International Cards
Visa
Mastercard
PLUS
Cirrus
Major banks such as KB, Shinhan, Woori and Hana often have foreign-card ATMs, especially in airports, stations and busy neighborhoods.
If one ATM fails, try another machine or another bank. It does not always mean your card is blocked.
To reduce fees, avoid tiny withdrawals. Taking out ₩300,000 once is usually better than taking out ₩50,000 six times, because ATM fees are often charged per transaction.
Should you bring USD, EUR or JPY cash?
Bring cash only if you already have it or prefer a backup.
USD, EUR and JPY are usually the easiest currencies to exchange in Korea. City money changers in areas like Myeongdong often post rates clearly, so you can compare before exchanging.
Do not bring obscure currencies and assume every booth will accept them. If your home currency is less common, an ATM or travel debit card is usually simpler.
What is the KRW rule?
When a card terminal or ATM asks which currency to use, choose KRW.
If you choose USD, EUR, GBP, AUD or your home currency, the machine may use Dynamic Currency Conversion. That means the merchant, ATM operator or payment provider sets the conversion rate.
It looks convenient because you see the amount in your own currency. But it is usually worse than letting your card issuer convert the payment.
Simple rule:
In Korea, pay and withdraw in KRW.
How much cash should you carry?
Most travelers do not need much cash in Korea.
Carry around ₩50,000–₩100,000 per person per week for:
traditional markets
street food
T-money top-ups
small restaurants
taxi backup
emergencies
Use cards for hotels, cafés, restaurants, shopping and attractions.

Use it to split your budget between card spending, ATM withdrawals, T-money top-ups and market cash.
Before you exchange
Check your home bank fees
Your real cost is the exchange rate plus ATM fees plus your bank’s foreign transaction fee.
Bring more than one card
One card can fail. Bring a backup Visa or Mastercard.
Avoid credit-card cash advances
Use a debit card for ATM withdrawals. Credit-card cash advances can be expensive.
Choose KRW every time
At ATMs and card terminals, reject home-currency conversion.
Do not leave with too much cash
Spend down your Korean won before departure or exchange it back before leaving. Re-converting leftover cash usually means losing on the spread twice.
