Essential Apps for Paying for Things in Korea

Short answer

Transit fares, tap-to-pay and splitting the bill.

Korea runs on tap-to-pay and QR. Locals use KakaoPay or Toss, but those need a Korean account, so visitors lean on prepaid cards, foreign contactless cards, or a T-money card for transit.

A WOWPASS card is the closest thing to paying like a local without a Korean bank account — load foreign money and tap.

Frequently asked

How should tourists pay in Korea?
Foreign contactless cards are widely accepted; for cash-free convenience get a WOWPASS card (loads foreign money, doubles as T-money). Korean wallets like KakaoPay need a local account.
Can I split a bill with friends using a Korean app?
KakaoPay makes splitting easy, but it needs a Korean phone number and account, so it's mainly for residents.
