Paying & cash for visitors
You can tap a card almost anywhere in Korea. A few small habits keep you from losing money at terminals and ATMs. Here’s what works, what to check, and why KRW is usually the better default.
DCC means letting the terminal convert to your home currency at its own marked-up rate. Enter the DCC markup shown on-screen and your own card’s foreign-transaction fee to compare the two paths.
| If you choose KRW | 105,500 KRW |
| If you let it convert (DCC) | 107,500 KRW |
| Difference | KRW is lower by 2,000 KRW (2.0%) from these inputs. |
A rough estimate from the figures you enter. The real fees depend on the terminal and your card, so check both before you pay. Nothing you type is stored.
Will my card work in Korea?
Usually yes. Visa, Mastercard and Amex are widely accepted at shops and restaurants. The weak spots are some kiosks, small or older shops, and certain ATMs. Korean payment apps are another gap, since you can’t set them up as a visitor.
Why is that? Everyday payments in Korea run on the domestic card network and on apps like KakaoPay and Naver Pay. Those apps generally need a Korean bank account and phone number. A foreign physical card gets around that, but a few terminals still won’t take it.
Choose KRW, not your home currency
When a card terminal or ATM asks whether to charge you in your home currency or in Korean won (KRW), KRW is usually the better default. Pick your home currency and you get DCC: the machine converts at its own marked-up rate.
Why is that? If you pick KRW, your own bank converts at the network rate and adds its foreign-transaction fee, which is usually smaller than the terminal’s markup. If you pick your home currency, you hand the conversion to the terminal, which sets a marked-up rate and keeps the difference.
Cash and ATMs
For cash, look for an ATM marked “Global,” or one at a major bank or convenience store. Those take foreign-issued cards. Have a 4-digit PIN ready, expect a small ATM operator fee, and choose KRW again if it asks.
Why is that? Not every Korean ATM is set up for foreign cards, and many expect a 4-digit PIN. Global ATMs and major-bank machines are the dependable ones. Your own bank may also add a withdrawal or FX fee on top of the ATM operator fee.
How much cash to bring when you land
Enough for your first day or two: airport transit, a meal, small shops. After that, withdraw more at a Global ATM. There’s no need to carry a lot of cash, since cards cover most things.
Why is that? You’ll want a little cash before you’ve found an ATM or sorted out a transit card, but you won’t get through it fast, because cards cover almost everything. Take out more as you go instead of carrying a lot at once.

Frequently asked
Some foreign cards get turned down at Korean ATMs and kiosks. Certain Visa debit cards are the usual culprits. Try a Global ATM or a major-bank machine, and keep a backup card plus some cash.
Korea is largely cashless, so cards work almost everywhere. A little cash still helps at small shops, markets, and some transit. Don’t rely on cash alone.
Not to tap a physical card. But Korean payment apps (KakaoPay, Naver Pay) usually need a Korean number and bank account, so visitors lean on a card plus cash.
