When you first arrive in Korea, one of the very first things you’ll need is a transportation card. Whether you stay in a metropolitan area or head to Seoul Station to take a train to another region, you’ll almost certainly use the subway or bus.
To live in cities with public transit — such as Seoul, Incheon, Gyeonggi-do, Busan, Dajeon, Daegu, or Gwangju —, a transportation card is essential.
If you already have a Korean bank account and can make a debit/credit card with a postpaid transportation function, you can simply use it. (I’ll write a detailed post on this soon!)
But, if you’ve just landed in Korea, you’ll need a prepaid card, which is a “T-money” card.
The Easiest Place to Buy a T-money Card: Convenience Stores!
You can buy a T-money card in several places, but the easiest option is any convenience store. Korea has four major convenience store brands, and you’ll see them everywhere.
The four brands are: GS25, CU, 7-Eleven, and Emart25.
Go into any of these, and you’re good to go.
Once you enter, just follow these three simple steps:
Step 1. Go to the Counter
Ask the staff for a “T-money card.”
You don’t need to say full sentences in English or Korean. Just saying “T-money card” is perfectly fine. Some staff may not be comfortable with English, so short, simple words work best.
If you’re under 18 and want the discounted fare, you may need to register your date of birth for the card.
Fares differ depending on age, so if you’re a teenager or buying a card for your child, make sure to tell the staff when purchasing.
In many cases, T-money cards purchased at convenience stores without a specific request are likely to be set to the adult fare by default.
When buying the card, you can ask the staff to register the card with a teen or child fare by showing an ID or providing the date of birth.
If your date of birth could not be registered at the place of purchase, you can still register or update the information later through the official T-money website by entering your card details and birthdate.
(Unfortunately, the page is currently available only in Korean, so you may need to rely on your browser’s built-in translation tool.)
Step 2. Choose a Card Design
T-money cards come in various designs, due to collaborations with K-pop idols, character brands, and seasonal editions.
However, the exact design you want may not always be available depending on the store you visit or the staff on duty.
Prices usually range from ₩2,500 to ₩5,000. The more special the design, the higher the price.
Step 3. Pay and Charge
While you can buy a T-money card by cash or card, most places still require cash for recharging.
So make sure to prepare some cash before charging!
Hand your money to the staff, place your card on the card reader, and the staff will do the rest.
How Much Should You Charge at First?
Now you may wonder
“How much money should I load on my T-money card?”🤔
Here is the public transportation fare table for the Seoul metropolitan areas as of January 2026.
| Basic fee (when you pay by T-money card) | |||
| Type | Adult | Adolescent | Child |
| Subway / Metro | ₩1,550 | ₩900 | ₩550 |
| Wide-area bus(city ↔️city, red buses) | ₩3,000 | ₩1,700 | ₩1,500 |
| Seoul city bus (blue/green) | ₩1,500 | ₩900 | ₩550 |
| Town shuttle bus (Maeul/village bus) | ₩1,200 | ₩600 | ₩400 |
* When you tag your card before getting off, additional distance-based fares may apply.
* Transfer discounts apply when you tag off and transfer to another bus or subway within 30 minutes (or 60 minutes during late-night hours).
* Airport buses are usually ₩8,000 – ₩12,000
💳 Recommended first charge (for adults):
If you use public transportation almost every day → ₩30,000
If you use it once or twice a week → ₩10,000
If you rarely use it → ₩5,000
💡 You can charge ₩1,000 – ₩90,000 at once.
💡Each card can store up to ₩500,000, so keep that in mind!
How to Check Your T-money Balance: Convenience Stores & Apps
There are several ways to check your T-money card balance.
1. At a Convenience Store
Just ask the staff to check your balance, same as when you first purchased the card.
But honestly, it’s a hassle to go there only to check it, especially when you’re not recharging.
2. Using Mobile Apps (No affiliate at all)
Here are two apps that are relatively easy to use and offer English support.
Before you use these apps, don’t forget to turn on your phone’s NFC.
🤖 For Android Users: “티머니, Rail+, 캐시비 잔액 조회” made by RW MobiMedia UK
🍎 For IOS Users: “교통카드 잔액조회-버카첵” made by RYNYUL
If you find a better app, then use it! (And let me know so that I can share it here!)
3. At the Gate (Turnstile)
Your balance pops up on the screen every time you tap your card at the gate!
How to Recharge: Convenience Stores & Subway Stations
When your T-money balance is low, it’s time to recharge. Normally, you should go to a convenience store.
But what if you can’t find one nearby?
Then, head straight to the subway station!
Huh?
You might think “What do you mean? How do I charge my card inside a subway station?”
Don’t worry. You still have two options. Inside a subway station, there is another convenience store brand, ‘Storyway,’ and unmanned charging machines! (surprise!)
The unmanned charging machines support English, Japanese, and Chinese. You can select your preferred language right from the first screen!
For now, recharging is still cash only.
The Seoul Metropolitan Government is gradually introducing new ticket kiosks at subway stations that allow T-money cards to be reloaded using overseas credit cards.
However, as of January 2026, these new kiosks are installed at only a very limited number of stations, so it is still safest to carry cash for recharging your T-money card.
A More Convenient Future: Using Your Own Credit Card for Korean Transit
If you’ve lived in Korea for a while and are used to using the T-money system, great!
And if you’re already using a Korean debit/credit card with the post-paid transportation card function, even better!
But if T-money still feels inconvenient or unfamiliar, here’s good news.
Starting in 2027, credit cards that you use in your home country will be gradually accepted on public transportation in Seoul!
By 2030, this open-loop payment system will expand to the entire Seoul metropolitan area.
Your credit card must support overseas payments such as Visa and Mastercard.
Isn’t that exciting?
Until then, I hope a cute T-money card in your wallet will take you to beautiful places in Korea! 🇰🇷✨
