Do you really need a transit card in Seoul? Short answer: yes, and it is the first thing worth buying after you land. Seoul's subway and bus network is fast, clean and cheap, but almost everything runs on tap cards. The most common one is T-money (티머니).

Below are the questions first-time visitors ask most, answered one by one. Fares in this guide were checked in November 2026. Prices in Korea change from time to time, so treat the numbers as a guide and look at the station screen if something seems different.

What exactly is a T-money card?

T-money is a rechargeable card you tap on a reader when you get on the subway or a bus. You load money onto it, and the fare is taken off each time you ride. It works on Seoul's subways and buses, and on public transport in most other big Korean cities too. Many taxis and convenience stores accept it as well.

You don't need a Korean ID, a Korean phone number or a bank account to buy or use one.

Where can I buy one?

• Convenience stores – GS25, CU, 7-Eleven and emart24 sell T-money cards at the counter. Just say "T-money card, please."
• Subway stations – many stations have card vending machines with an English menu.
• The airport – convenience stores in the arrival halls at Incheon and Gimpo airports sell them, so you can be ready before your first train.

A plain card usually costs a few thousand won. Cards with cartoon characters or K-pop designs cost more. Note that a new card normally comes with zero balance, so you need to load money right away.

How do I top it up?

1. Find a ticket and top-up machine (교통카드 충전) in any subway station, or go to a convenience store counter.
2. Put the card on the machine's card tray, choose English, and select "Top up" or "Recharge."
3. Choose an amount and insert cash. At a convenience store, hand over the card and the cash and say how much.

The important part: top-ups are usually paid in cash. Keep some 10,000-won notes handy. Loading 10,000–20,000 won at a time is plenty for a few days of normal sightseeing.

How much is a ride?

Since June 28, 2025, the basic adult subway fare in Seoul is 1,550 won with a transit card. That covers the first 10 km; longer trips add a little more, and the gate calculates it for you when you tap out.

If you buy a single-journey ticket from a machine instead, the fare is higher (1,650 won) plus a 500-won deposit. You get the deposit back by putting the used ticket into the refund machine near the exit. That is a lot of extra steps for every trip, which is why most visitors get a T-money card.

How do I use it on the subway?

• Tap in at the gate when you enter, and tap out at the gate when you leave. The screen shows the fare and your remaining balance.
• Don't forget to tap out. The fare is based on distance, and transfers only count if the system knows where you got off.
• Signs and announcements are in Korean and English, and stations have three-digit numbers (Gangnam on Line 2 is 222, for example). Lines are color-coded.

And on the bus?

• Get on through the front door and tap the reader next to the driver.
• When you get off through the back door, tap the reader by the back door too. Many tourists skip this, but it matters: without tapping off, you lose the free transfer.
• Press the stop button before your stop. Bus screens and announcements usually show stop names in English.

Are transfers really free?

Mostly, yes. In Seoul and the surrounding area, if you switch between subway and bus (or between different bus routes) within 30 minutes of tapping off, you don't pay a new basic fare. You only pay extra if the total distance is long. The window is longer late at night, from 9 p.m. to 7 a.m. (1 hour). You can transfer several times on one journey.

Two exceptions catch people out: getting back on a bus with the same route number does not count as a transfer, and neither does leaving a subway station through the gates and entering again.

The rule only works with a transit card, and only if you tapped off properly. That is the real reason locals always tap when they get off the bus.

Is there an unlimited pass for tourists?

Yes. Seoul's Climate Card (기후동행카드) short-term pass gives unlimited rides on Seoul subways and city buses for a set number of days. Prices are:

• 1 day: 5,000 won
• 2 days: 8,000 won
• 3 days: 10,000 won
• 5 days: 15,000 won
• 7 days: 20,000 won

The physical card itself costs an extra 3,000 won. It does not cover everything. On lines that run beyond Seoul, you can ride out of the city but can't start a trip at a station outside Seoul. The Shinbundang Line, AREX express trains, intercity buses and airport limousine buses are not included. You can buy the physical card at convenience stores near stations or at station customer service offices, and charge the pass at ticket machines in Seoul subway stations. Since March 17, 2026, those machines also accept overseas Visa and Mastercard cards for short-term Climate Card passes and single-journey tickets, with a small extra service fee.

Is it worth it? Do the math. At 1,550 won per ride, a 3-day pass (10,000 won plus 3,000 won for the card) pays off only if you take at least three rides a day, every day. If you mostly walk around one neighborhood, a regular T-money card is simpler.

Can I get my money back when I leave?

You can get a refund of the remaining balance, but not the price of the card itself. Major convenience stores can refund small balances for a small fee (around 500 won), and larger balances are handled at T-money service centers. The limits differ by store, so ask at the counter. Many travelers simply spend the last few thousand won on snacks at a convenience store before heading to the airport, which is easier.

A few mistakes to avoid

• Two cards in one wallet. If you tap a wallet holding two transit cards, the reader may charge the wrong one or show an error. Take the card out.
• Low balance on the bus. If your balance is too low, the reader beeps and the driver can't top you up. Check the balance at the subway gate screen before boarding.
• Rush hour. Trains between about 8 and 9 a.m. and 6 and 7 p.m. are packed. If you have big luggage, try to travel outside those times.
• Priority seats. The seats at the ends of each car are for elderly passengers, pregnant women and people with disabilities. Locals leave them empty even when the train is crowded.

Once you have a charged T-money card in your pocket, Seoul feels much smaller. You can hop on a train to a palace in the morning, grab a bus to a market at lunch, and head out for Korean BBQ at night without thinking about tickets. If that BBQ dinner is on your list, our Korean BBQ guide for first-timers walks you through the whole meal.
