How to Pay in Korea: Credit Cards, Cash, T-money & Useful Korean for Tourists
Paying for things in Korea is usually easy, but the system can surprise first-time visitors.
Your foreign credit card may work perfectly at a hotel and then fail at a smaller shop. You may be able to tap your card at a restaurant but still need Korean won to recharge a transportation card. And if a cashier asks 일시불이세요?, you may have no idea what they are asking.
The safest approach is not to depend on a single payment method.
1. An international credit or debit card
2. A small amount of Korean won in cash
3. A transportation card such as T-money
This guide explains when to use each one, what to do when your card does not work, and the Korean expressions you are most likely to hear when paying.
Can Foreigners Use Credit Cards in Korea?
Yes. Credit and debit cards are widely used in Korea, and many visitors can make most everyday purchases by card.
Hotels, department stores, supermarkets, convenience stores, restaurants, cafés and many other businesses routinely accept card payments.
But “cards are widely accepted” does not mean that every foreign-issued card will work everywhere.
A transaction can fail because of the card issuer, payment network, merchant terminal, online verification system or the way a particular payment service is configured.
That is why I would not travel in Korea with only one card and no cash backup.
Which Cards Are Most Useful in Korea?
Internationally enabled Visa and Mastercard cards are generally the most practical cards for travelers to carry. Other international card networks may also be accepted, but acceptance can vary.
Before traveling, check that your card:
- is enabled for international transactions,
- has not been blocked for overseas use,
- has a PIN you know if one is required, and
- does not charge an unexpectedly high foreign-transaction fee.
If possible, carry two cards from different issuers or networks. If one card is declined, you have another option immediately.
Do You Still Need Cash in Korea?
Yes, but usually not a large amount.
Korea is highly card-oriented, so many visitors use cards for most purchases. Cash is still useful as a backup and for situations where a foreign card is inconvenient or cannot be used.
For example, cash can be useful for:
- recharging a transportation card at certain locations,
- some traditional markets or small businesses,
- cash-only machines or services,
- small unexpected purchases, and
- situations where your foreign card is declined.
I would therefore think of Korean cash as a backup and problem-solving payment method, rather than something you need for every purchase.
Korean Won: The Banknotes You Should Recognise
South Korea's currency is the Korean won, written as 원 in Korean and commonly shown with the symbol ₩.
The banknotes visitors are most likely to use are:
| Banknote | Korean | Useful way to think about it |
|---|---|---|
| ₩1,000 | 천 원 | one thousand won |
| ₩5,000 | 오천 원 | five thousand won |
| ₩10,000 | 만 원 | ten thousand won |
| ₩50,000 | 오만 원 | fifty thousand won |
One number is especially useful to learn:
₩10,000 = 만 원
₩20,000 = 이만 원
₩30,000 = 삼만 원
₩50,000 = 오만 원
Korean prices often become easier to understand once you recognise 만.
Where Should You Get Korean Cash?
You do not necessarily need to arrive in Korea carrying a large amount of won.
Travelers can obtain Korean won through currency exchange or by withdrawing cash from a compatible ATM. However, not every ATM works equally well with foreign-issued cards, and fees can vary.
If you plan to withdraw cash after arrival, see our guide to withdrawing cash in Korea with a foreign card for the ATM process and common problems.
Credit Card, Cash or T-money?
These payment methods have different jobs. T-money should not be treated as a replacement for your normal credit or debit card.
| Situation | Usually most useful |
|---|---|
| Hotel | Credit/debit card |
| Restaurant or café | Credit/debit card |
| Convenience store purchase | Credit/debit card or cash |
| Subway or bus | Transportation card such as T-money |
| T-money recharge | Keep Korean won available because recharge arrangements vary |
| Foreign card fails | Second card or cash |
For transportation-card details, including buying and recharging the card, read T-money Card in Korea: How to Buy, Recharge, and Use It Like a Local.
Why Can a Foreign Card Fail in Korea?
A declined card does not necessarily mean that the business does not accept cards.
Possible reasons include:
- your bank blocking an overseas transaction,
- the merchant's terminal or payment processor not handling your card correctly,
- online authentication requirements,
- a problem with contactless payment, or
- a temporary network or issuer problem.
If tapping the card fails, inserting the physical card may sometimes work.
If the transaction is still declined, the fastest solution is usually to try another card or pay with cash rather than spending a long time troubleshooting at the counter.
What Should You Say If Your Card Does Not Work?
You can ask:
I kadeu an dwaeyo?
Does this card not work?
Or ask whether you can try another card:
다른 카드로 해 볼게요.
Dareun kadeuro hae bolgeyo.
I'll try another card.
If you decide to use cash:
현금으로 할게요.
Hyeongeumeuro halgeyo.
I'll pay in cash.
How to Say “I'll Pay by Card”
The simplest useful expression is:
Kadeuro halgeyo.
I'll pay by card.
For cash:
현금으로 할게요.
Hyeongeumeuro halgeyo.
I'll pay in cash.
You often do not need to say anything at all. At many counters, simply presenting your card makes your intention obvious.
A Korean Payment Question That Can Confuse Visitors: 일시불이세요?
When paying by credit card, you may occasionally hear:
Ilsiburiseyo?
일시불 means paying the card purchase in one payment rather than dividing it into installments.
Installment payment is familiar to Korean card users, so the question can appear in situations where a visitor is not expecting it.
If you are using an ordinary foreign card and are simply making a normal purchase, you can answer:
네, 일시불이요.
Ne, ilsiburiyo.
Yes, one payment.
The exact payment options available ultimately depend on the card and transaction, but recognising the word 일시불 prevents an otherwise simple checkout question from becoming confusing.
Paying at Korean Restaurants and Cafés
At many Korean restaurants, you pay at the counter rather than waiting for a server to bring a card machine to your table.
When you are ready to leave, look near the entrance for the register.
A useful phrase is:
계산할게요.
Gyesanhalgeyo.
I'd like to pay.
At cafés, the payment process is generally straightforward: order, pay, and then wait for your drink.
Paying at Korean Convenience Stores
Convenience stores are generally easy places to pay by card, but the cashier may ask several short questions during checkout.
For example:
봉투 필요하세요?
Do you need a bag?
영수증 필요하세요?
Do you need the receipt?
적립하세요?
Are you collecting membership points?
If you do not need something, 아니요, 괜찮아요 is often enough.
For 1+1 deals, ramen, microwaves, T-money and the complete checkout routine, see How to Use a Korean Convenience Store.
Paying for Taxis
Card payment is common in Korean taxis, and transportation-card payment may also be available depending on the taxi and system.
Still, it is sensible to have a backup payment method.
If you want to ask whether card payment is possible:
카드 돼요?
Kadeu dwaeyo?
Can I pay by card?
For visitors, the larger challenge is often not the payment itself but knowing which taxi to take, how to communicate the destination and which taxi apps are useful.
Paying at Hotels
Hotels commonly accept major cards, but your booking and the hotel may treat prepayment, payment at the property and deposits differently.
The card used to guarantee a reservation is not necessarily the same thing as completing the final payment.
Check your booking terms rather than assuming that showing a reservation confirmation means everything has already been paid.
What About Apple Pay and Other Mobile Payments?
Mobile-payment availability in Korea continues to change, and compatibility can depend on the device, card issuer, payment network and merchant terminal.
For that reason, I would not make a phone wallet your only way to pay during a trip.
Even if you normally pay exclusively with your phone at home, carrying a physical card and some Korean won gives you a reliable backup.
Useful Korean Words You Will See When Paying
| Korean | Reading | Meaning |
|---|---|---|

| 영수증 | yeongsujeung | receipt |
| 일시불 | ilsibul | single payment / no installments |

I'll pay by card.
현금으로 할게요.

A Practical Payment Setup for Your Korea Trip
If I were preparing for a trip to Korea, I would keep the setup simple.
Primary payment: an internationally enabled credit or debit card.
Backup: a second card, preferably from a different issuer or network.
Cash: enough Korean won for transportation-card recharging, small purchases and unexpected card problems.
Transport: a transportation card such as T-money for convenient subway and bus travel.
This is more reliable than trying to predict whether one particular card, app or mobile wallet will work in every situation.
Frequently Asked Questions
Can I travel in Korea without cash?
You may be able to make most purchases by card, but I would not recommend carrying no cash at all. A modest amount of Korean won is useful for transportation-card recharging and as a backup when a foreign card does not work.
Are foreign credit cards accepted in Korea?
They are widely accepted, particularly at hotels, department stores, restaurants, cafés, convenience stores and other established businesses. However, individual foreign-card transactions can still fail, so carry a backup payment method.
Should I exchange a lot of money before going to Korea?
Usually there is no need to carry a large amount of cash if you have working international cards. How much cash you need depends on your spending habits and itinerary.
Can I withdraw Korean won with a foreign card?
Yes, compatible ATMs can accept international cards, but ATM compatibility and fees vary. Look for an ATM that supports international cards and check the fee shown before confirming the transaction.
Can I use T-money instead of a credit card?
T-money is primarily useful as a transportation and stored-value card. It should not be treated as a complete replacement for a normal payment card or cash.
Why was my foreign card declined?
A card can be declined because of issuer restrictions, overseas-use settings, payment-network compatibility, terminal issues or authentication requirements. Try the physical card, another card or cash.
Should I rely on Apple Pay in Korea?
I would not rely on any mobile wallet as your only payment method. Compatibility can vary by card and merchant, so carry a physical card and some Korean won as backup.

The Simple Rule

Then learn just enough Korean to recognise what is happening at the counter.
