Mastering Korea’s Public Transportation : How to Use the T-money Card and Travel Like a Local

 

Is Korea’s Public Transit Really That Easy?

Many first-time visitors to Korea say the same thing:
“I had no idea how to use the buses or subways when I first arrived.”

Despite having one of the most advanced transportation systems in the world,
language barriers and unfamiliar rules can make it feel overwhelming at first.

But here’s the good news —
Once you know how to get started, Korea’s transit system becomes incredibly easy and efficient.

In this post, I’ll walk you through exactly how to use the T-money transportation card,
along with helpful tips to make your journey smoother — even if you don’t speak a word of Korean.


What Is the T-money Card?

T-money transportation card available at CU convenience store in Korea

T-money cards are available at major convenience stores like CU, GS25, and 7-Eleven, as well as at airports across Korea.


The T-money card is Korea’s most widely used prepaid transportation card.

You can use it for:

  • Subways
  • Buses
  • Some taxis
  • Even purchases at convenience stores and vending machines

It works in most major cities including Seoul, Busan, Daegu, and even Jeju Island.
Just tap when you board and tap again when you get off. That’s it!



Where to Buy a T-money Card

1. At the Airport

As soon as you arrive at Incheon International Airport,
you’ll find T-money cards available at most convenience stores (like GS25, CU) and info desks.

2. At Any Convenience Store

You can also buy one at most convenience stores across Korea.
The card usually costs ₩2,500 to ₩4,000, and you’ll need to add balance separately.


How to Recharge Your T-money Card

Because it’s a prepaid card, you need to charge it with money before use.

Here’s how:

  • At convenience stores: Simply hand the card to the cashier and ask to recharge it. You can pay by cash or card.
  • At subway stations: Use the multilingual recharge machines.
  • You can top up in small amounts — even ₩1,000 is okay.

Can I Use T-money on My Phone?

Yes! If you have a phone with NFC capability, you can use Mobile T-money apps.

Works with:

  • Samsung Pay
  • Apple Pay
  • Kakao Pay (widely used in Korea)

You can tap your phone just like a card and recharge directly from the app.
Just make sure your NFC is turned on!


Can I Pre-Order a T-money Card?

Absolutely.

If you’d prefer to skip the lines or ensure availability,
you can pre-order a T-money card online and pick it up at the airport when you arrive.

For example:
