What to know about Transit in South Korea

Naver Map is enough for route planning in Seoul, Busan, Daegu, Daejeon, Gwangju and other urban networks, so a separate subway diagram is optional rather than essential.

Best Transit apps in South Korea (2026)

The Android visitor version of mobile Tmoney for compatible NFC phones, with transit use and tourist benefits.

Pro tip: Compatibility and NFC setup vary by phone. Do not load a large balance until one tap-in and tap-out has worked.

Public transport payment is a separate problem. An ordinary foreign contactless bank card still does not act as a universal tap-in card at subway gates or buses. Each passenger needs an accepted transit card or mobile transit balance and must tap both when boarding and, where required, when leaving. A physical Tmoney card remains the simplest universal fallback.

Buy one from a staffed convenience store or station, keep some won for top-ups and avoid loading more than you expect to use. MobileTmoney became genuinely visitor-ready on iPhone in 2026. Its current foreigner flow needs no sign-up, adds Tmoney to Apple Wallet and accepts supported overseas cards through Apple Pay. Current compatibility requires an iPhone XS or XR or newer with iOS 17.2 or later, or a supported Apple Watch.

Mastercard, American Express, UnionPay and JCB are listed in the August 2026 App Store version, but card, issuer and region support can still fail. Android visitors should use the separate KOREA TOUR CARD Tmoney app only on a compatible NFC Android device. Device and NFC behavior vary, so carry a physical card until the mobile card has completed a real trip. Seoul ticket machines began accepting international cards in March 2026 for short-term Climate Card passes and single-journey tickets.

That is a machine purchase, not direct bank-card tapping at every gate. Climate Card coverage and value are Seoul-specific, so compare it with pay-as-you-go Tmoney for the actual itinerary.
