1. How People Pay in Korea Today

Korea is highly digital, and most locals rarely carry cash. Credit cards, debit cards, transportation cards, and mobile wallets are common in daily life. Visitors will notice that:

  • You can live almost entirely without cash.
  • Foreign cards work in most major stores and restaurants.
  • T-money is essential for public transportation.
  • Mobile wallets are extremely popular among locals.

Let’s break down each method so you can choose the best setup for your stay.

2. Cash in Korea

Cash is accepted everywhere but used less each year. Still, having a small amount is helpful when visiting:

  • Traditional markets
  • Small family-run restaurants
  • Rural or older neighborhoods
  • Vendors without card readers

Use convenience store ATMs marked “Global,” “PLUS,” or “CIRRUS” for foreign cards.

3. Debit & Credit Cards

Cards are the main payment method in Korea. Visa and Mastercard are widely accepted; American Express and JCB are less common but still supported in many places.

Using a foreign card:

  • Accepted at most restaurants, cafes, and chain stores.
  • Some small shops may prefer Korean cards, but this is becoming rare.
  • Choose KRW instead of “your home currency” for a better exchange rate.

Getting a Korean card:

  • Long-term expats with an ARC can open a Korean bank account.
  • Korean “check cards” (debit cards) work well with local apps and mobile wallets.

4. T-money Transportation Card

T-money is Korea’s universal transportation card used on buses, subways, taxis, and even some convenience stores.

  • Buy it at CU, GS25, 7-Eleven, subway stations, or airports.
  • Recharge it at convenience stores or subway machines.
  • Tap in and out for subways; tap when boarding and exiting buses.

5. Mobile Wallets (KakaoPay, Naver Pay, Toss)

Mobile wallets are extremely popular among younger Koreans. They support QR payments, online shopping, bill splitting, and subscriptions.

Main options:

  • KakaoPay – Most widely used; integrated with KakaoTalk.
  • Naver Pay – Strong for cafe payments and online shopping.
  • Toss – A finance super-app offering transfers, cards, and budgeting.

Important: Most mobile wallets require a Korean phone number and a Korean bank account, so short-term visitors may not be able to use them.

You need:

  • Online banking or a banking app

Transfers are fast, reliable, and often free between major banks, making them a preferred option for locals.
