Hello. This is JH from My Korean Guide.
If you’ve just started living in Korea, one of the very first things you need to learn is how to use public transportation.
Korea has one of the most efficient and affordable public transportation systems in the world, including subways, buses, taxis, and high-speed trains like KTX.
However, for foreigners, transportation cards, transfer rules, and route systems can feel confusing at first.
This guide covers everything first-time visitors and residents need to know about public transportation in Korea.
1. Transportation Cards: T-money & the T-money Travel Card (For Tourists)
Public transportation in Korea is built around T-money.
In the past, a foreigner-only card called the Korea Tour Card was available, but it has been discontinued.
Instead, Korea has introduced a new option designed specifically for international travelers.
✅ T-money Travel Card
The T-money Travel Card is a tourist-friendly transportation card that works nationwide.
