When I visited the Netherlands, I ran into an unexpected problem: paying for things wasn't always as simple as I thought it would be.
Coming from Korea, I was used to paying for almost everything with my credit card. I rarely carried much cash, so I assumed I could do the same abroad.
But in the Netherlands, I soon discovered that many places preferred debit cards, particularly local bank cards, or cash. Some places simply wouldn't accept my credit card.
The trouble was, I didn't have a Dutch bank account yet, so I couldn't use a local debit card. And with my busy schedule, I hadn't had time to withdraw enough cash, either.
It caught me off guard. I had money available, but I couldn't always pay the way I was used to!
That experience taught me something important: just because a country is modern and largely cashless doesn't mean your usual payment method will work everywhere.
So, if you're planning a trip to Korea, here's what you should know about paying with cash, credit cards, and transportation cards.
1. Can You Use Credit Cards in Korea?
The short answer is yes, in most places.
Credit and debit cards are widely accepted in Korea, including at:
Restaurants and cafés
Convenience stores
Department stores and supermarkets
Hotels
Most shops and tourist attractions
As a Korean, I hardly think twice about pulling out my credit card, even when I'm buying something inexpensive.
For foreign visitors, internationally issued Visa and Mastercard cards are generally useful, although acceptance can vary depending on the merchant and card issuer.
A Korean's tip: Bring more than one payment method. Even if your card works perfectly at one shop, it might be declined somewhere else.
2. Do You Still Need Cash in Korea?
Yes, but you probably won't need to carry large amounts.
Although Korea is highly card-friendly, cash can still come in handy in certain situations.
For example:
Buying food at some traditional market stalls
Shopping at small street vendors
Topping up a standard T-money transportation card
Paying when a shop's card terminal isn't working
One important thing to remember is that a shop accepting Korean credit cards doesn't necessarily mean every foreign-issued card will work.
This is exactly the kind of thing I learned the hard way in the Netherlands.
3. How Much Cash Should You Carry?
There's no fixed amount, but for a first-time visitor, I'd suggest keeping around ₩30,000–₩50,000 in cash for small purchases and unexpected situations.
You can rely mainly on your card and withdraw more cash when necessary.
It's also worth carrying a few smaller bills, especially if you're planning to visit traditional markets.
You don't need to exchange all your travel money into Korean won before arriving.
However, make sure you have a way to access cash once you're in Korea.
4. Where Can You Withdraw Cash in Korea?
You'll find ATMs at banks, convenience stores, and other locations throughout Seoul.
But here's something tourists should know.
Not every Korean ATM accepts foreign-issued cards.
Look for machines marked Global ATM or displaying your card network's logo.
Before travelling, check whether your bank allows international withdrawals and what fees may apply.
Also, remember that an ATM withdrawal may involve both a local machine fee and a fee from your own bank.
A Korean's tip: Don't wait until you're completely out of cash to look for an ATM. Withdraw a little in advance, particularly before visiting traditional markets or less touristy areas.
5. What About T-Money Cards?
If you're planning to use Seoul's public transportation, you'll probably want a T-money card.
It's a rechargeable card used for buses, subways, and other participating services.
You can buy one at convenience stores and participating subway stations.
But here's the important part: don't assume you can top up a standard T-money card using your foreign credit card.
Cash is still the most dependable option at ordinary top-up locations, although some newer machines and services support additional payment methods.
This is one reason I'd recommend keeping some Korean won in your wallet even if you plan to use your credit card for everything else.

6. Can You Use Apple Pay or Other Mobile Payments?
Mobile payments are becoming increasingly common in Korea, but compatibility isn't universal.
You may be able to use Apple Pay at participating merchants, while some Korean mobile payment services require local bank accounts, phone numbers, or other domestic credentials.
Don't assume that every shop accepting contactless payments will accept your particular phone or digital wallet.
For foreign visitors, a physical Visa or Mastercard is still a sensible backup.
7. What Should You Do If Your Card Gets Declined?
First, don't panic.
A declined card doesn't necessarily mean there's anything wrong with your account.
It could be a temporary connection issue, a merchant restriction, or a problem with international card acceptance.
Here's what I'd try:
Ask whether the shop accepts your card network.
Try another credit or debit card.
Use cash if it's accepted.
Contact your card issuer if the problem continues.
One useful Korean phrase is:
카드 돼요? (Kadeu dwaeyo?)
Can I pay by card?
And if you want to ask specifically about a foreign-issued card:
해외 카드 돼요? (Haeoe kadeu dwaeyo?)
Do you accept foreign cards?
These simple phrases can save you some awkward moments at the checkout.
Cash vs. Card in Korea: A Quick Guide
| Situation | My recommendation |
|---|---|
| Restaurants and cafés | Credit or debit card |
| Convenience stores | Credit or debit card |
| Shopping malls | Credit or debit card |
| Traditional markets | Card, with cash as backup |
| Street food stalls | Check first; carry cash |

Final Thoughts
My experience in the Netherlands reminded me that payment habits can be surprisingly different from one country to another.
What seems completely normal to locals can catch a visitor off guard.
Fortunately, Korea is generally very convenient when it comes to paying for everyday things. You can get by with a credit card in most situations.
Still, I wouldn't recommend relying on just one payment method.
Bring a credit or debit card, keep some Korean won handy, and make sure you can withdraw cash if needed.
That way, you can spend less time worrying about payments and more time enjoying your trip.
And take it from someone who learned this lesson abroad: a little preparation can save you a lot of hassle.😄
