Money & payments in Korea

Use a simple three-part setup

Will my foreign card work?

International cards are widely accepted in major cities. A card can still fail because of the issuer, terminal, online verification or the business setup.

• Enable overseas transactions before departure.
• Know your PIN and check your issuer's foreign-transaction fees.
• Choose Korean won when a terminal offers currency conversion.
• Keep another payment method ready for kiosks and small businesses.

How much cash should I carry?

Start with enough for transport-card loading and one low-cost day, then withdraw more only if needed. Look for an ATM marked Global or showing your card network. Availability and fees vary by machine and issuer.

Transport cards are a separate wallet

Prepaid cards such as Tmoney work across much of Korea's bus and subway network and at some shops. Physical cards are sold at many convenience stores and stations. Reload options vary, so cash remains the safest assumption for top-ups.

Visitor-focused alternatives may combine transport and payment features. Compare fees and coverage with your itinerary rather than assuming one product is essential.

Money manners

Tipping

Not generally expected in everyday restaurants, cafés or taxis. Some premium services may add a service charge.

Splitting bills

Paying as one group is common; friends often settle afterward.

Tax refunds

Keep your passport, receipts and unused goods available when required.
