Paying for things in Korea

Cards are widely accepted in Seoul, but carry some cash anyway — transit card top-ups, market stalls and older machines can still need it.

STEP BY STEP

Do it in this order.

Each step names the sign to look for where one exists, and what travellers most often get wrong.
  1. 01
    Tell your bank you are travelling, if it requires notice

    Some banks block foreign transactions without notice. Check your own bank's policy before you fly, because resolving it from Korea is slow.

    Watch out A blocked card at an airport transit machine is a bad place to discover this.

  2. 02
    Bring a second card and keep it somewhere else

    Two cards from different networks, stored in different places, covers loss, theft, a bank block, and a merchant that only takes one network.

    Watch out Two cards in the same wallet solve none of those problems.

  3. 03
    Get some Korean won early

    You do not need a large amount, but you need some. Transit card purchase or top-up may require cash, and so may some market stalls.

    Watch out Not every ATM accepts foreign cards. Look for ones that display international network logos.

  4. 04
    Choose a transit card after you know your routes

    Compare T-money against Seoul's short-term Climate Card based on how much you will actually travel, rather than buying both on arrival.

    Watch out This is the single most common place a traveler needs cash in Korea.

  5. 05
    Check before you order in smaller places

    In markets, small restaurants and older cafés it is normal to confirm payment method before ordering. A short question avoids an awkward situation.

    Watch out Some places are cash-only and will not say so in English on the door.

  6. 06
    Keep enough cash for the way home

    Set aside a small reserve for a taxi or a transit top-up so a payment problem never becomes a getting-home problem.

ALTERNATIVES

Compare before you commit.

There is no single best option. The right one depends on your luggage, your arrival time and where you are staying.

COMMON MISTAKES

What goes wrong most often.

Arriving with one card and no cash.

Carry a second card and some won. Nearly every payment horror story starts with a single point of failure.

Assuming a card works because the shop takes cards.

Foreign-issued cards are accepted less universally than domestic ones. Ask first in smaller venues.

Exchanging a large sum at the airport out of anxiety.

Get enough to be safe, then decide the rest once you are in the city and know your actual spending.

Buying a transit card before checking your routes.

Compare T-money with the short-term Climate Card first. The cheaper option depends on your itinerary.

TRAVELER FAQ

Answers before you leave.

Will my card work on the subway?

Check the current foreign-card options in the official Korea Tourism Organization transport guide, and carry cash as a backup for the top-up machine.

Should I use ATMs or exchange counters?

Both work. Compare your own bank's withdrawal fees against the counter rate. What matters more is that not all ATMs take foreign cards, so do not leave it until you are out of cash.

Is tipping expected?

Tipping is not a general expectation in Korea. Paying the stated price is normal and not considered rude.

Can I pay with my phone?

Domestic mobile payment systems are widespread but often require a Korean bank account or card. Do not plan around them as a visitor.

What if my card is declined everywhere?

Use your backup card and contact your bank. This is exactly why the second card and the cash reserve exist.
