If you need a simple way to pay for buses, subways, and some taxis in South Korea, buy a rechargeable T-money card at a convenience store. The process is usually quick: ask for a card, pay for the card itself, then add a cash balance before using it.
Most major convenience-store chains—including CU, GS25, 7-Eleven, and emart24—sell T-money cards, although stock and card designs vary by branch. Look for a small display near the register or ask the cashier directly.
What you need before you start
- Korean won in cash for the safest and most widely accepted top-up method.
- A decision about how much balance to load. For a short stay, a modest amount is usually enough to begin.
- Your destination or route, if you want the cashier to help estimate a starting balance.
The card purchase price and the travel balance are separate. When you buy a card, you pay for the physical card; when you load it, you add money that can later be used for transportation and participating stores. The card fee is generally not part of the refundable balance.
Step 1: Ask for a T-money card
At the register, say:
티머니 카드 하나 주세요.
T-money kadeu hana juseyo.
“Please give me one T-money card.”
You can also simply say 티머니 하나 주세요 (T-money hana juseyo). If the branch sells several designs, the cashier may show you a choice. Standard cards are usually the easiest option; character or limited-edition designs may cost more or be unavailable.
In some locations, especially busy tourist areas, cards may be displayed openly. In others, they are kept behind the counter. If the cashier does not understand “T-money,” showing the words 티머니 on your phone can help.
Step 2: Pay for the card
Pay for the physical card at the register. The cashier may ask whether you also want to charge it immediately. If you do, say:
충전해 주세요.
Chungjeonhae juseyo.
“Please load it.”
You can specify an amount by saying, for example:
만원 충전해 주세요.
Mannwon chungjeonhae juseyo.
“Please load 10,000 won.”
Hand over the cash. The cashier will place the card on a reader, enter the amount, and return the card with a receipt if one is printed. Keep the card and receipt until you have confirmed that the balance was added.
Can you top up with a foreign credit card?
Do not assume that you can load a T-money card directly with a foreign Visa or Mastercard. Convenience-store top-ups are traditionally handled in Korean won cash, and acceptance of non-Korean cards can depend on the store’s payment system and current policy. A foreign card may work for buying some products at a convenience store while still not being accepted for a T-money reload.
The practical approach is to withdraw Korean won from an ATM or exchange enough currency before topping up. If you want to test a card payment, ask first:
외국 카드로 충전돼요?
Oeguk kadeuro chungjeondwaeyo?
“Can I top it up with a foreign card?”
If the answer is unclear, use cash rather than delaying the transaction at a busy register.
How much should you load?
Start with an amount that matches your immediate plans instead of loading your entire travel budget. Your balance is used when you tap in and out of the subway or when you board and leave a bus. Fares vary by route, distance, transfer pattern, and transport type, so the most useful starting amount depends on your itinerary.
A modest first top-up lets you check that the card works and reduces the inconvenience of having excess balance at the end of your trip. You can reload at another convenience store whenever necessary. Many subway stations also have recharge machines, but their language options, payment methods, and availability can differ.
How to use the card on public transportation
On a subway journey, tap the card on the reader at the entrance and again at the exit. On a bus, tap when boarding; depending on the route and your travel plans, tap again when getting off. Keep the card separate from other contactless cards in your wallet so the reader does not detect the wrong card or fail to read it.
Do not pass one card between several passengers. Each person should use a separate card if you want the correct fare and transfer records. If you are traveling with children, ask the operator or station staff about the appropriate fare registration before using the card.
What else can a T-money card pay for?
T-money is primarily useful for transportation, but it may also work at participating convenience stores, vending machines, lockers, taxis, and other affiliated merchants. Acceptance is not universal, so look for a T-money mark or ask before paying. A successful transit card does not guarantee that every shop or machine will accept it.
Common problems and what to do
The store does not sell T-money cards
Stock varies by branch. Try another convenience store, a subway-station service counter, or a transportation-card vending machine. Large stations and tourist districts are more likely to have cards, but availability is never guaranteed at a particular register.
The cashier cannot understand you
Show 티머니 in writing and use the short phrases above. You can also type the amount into a translation app. The transaction itself is routine, so a written request is often enough.
The card did not work at the gate
Check that you tapped the correct side or area of the card and that it is not being blocked by another transit or bank card. If the reader reports a balance problem, visit a station office or ask a convenience-store cashier to check whether the reload was processed. Keep your receipt if you have one.
You loaded too much money
Refund procedures depend on where you request the refund and the card’s balance. The remaining stored value may be refundable at designated service points, while the physical card purchase fee is generally treated separately. Ask before handing over the card:
환불할 수 있어요?
Hwanbulhal su isseoyo?
“Can I get a refund?”
For a small remaining balance, spending it at an accepting convenience store may be simpler than arranging a refund. Do not throw away the card until you have checked whether you still have usable balance.
A quick checkout script
If you want to buy and load a card in one transaction, this is enough:
티머니 카드 하나 주세요. 만원 충전해 주세요.
T-money kadeu hana juseyo. Mannwon chungjeonhae juseyo.
“One T-money card, please. Please load 10,000 won.”
Then pay in cash, wait for the cashier to complete the reload, and keep the card accessible for your first tap. Once it is loaded, the card is usually the fastest way to begin using Korea’s local transit without buying a separate ticket for every ride.
