Last checked: August 3, 2026. Transportation fares, T-money reload methods, ticket-machine payment support, transfer rules, airport ticketing and digital transit options can change. Confirm time-sensitive details through the official sources linked below before traveling.
Using a T-money card in Seoul follows one simple rhythm: tap the same card when entering and leaving the subway, and tap when boarding and getting off a bus. Keep the card close to the reader, wait for the confirmation sound or screen response, and then move through.
The parts that confuse first-time visitors are usually not the tap itself. The bigger questions are where to buy the card, how to reload it, why some new subway machines accept foreign cards, whether Apple Wallet changes the rules, how transfers work and which airport services require a separate ticket.
Quick answer: Buy an ordinary T-money card at a participating sales point, keep Korean-won cash available for standard physical-card reloads, use the same card at subway entry and exit, tap when boarding and leaving a Seoul bus, and do not confuse international-card ticket machines with direct foreign-card gate payment. AREX All-Stop trains accept prepaid transportation cards, while the AREX Express Train requires its own ticket.
What a T-money Card Does
T-money is a rechargeable prepaid transportation card used on Seoul subways, city buses and other participating transportation services. The fare is deducted from the stored balance when the card is tapped.
It can also be accepted by participating taxis and merchants displaying the relevant Tmoney logo, but it should not be treated as a universal bank card. Acceptance depends on the operator, merchant and payment terminal.
The purchase price of the physical card is separate from the transportation balance. Buying the card does not automatically give you enough stored value for your first ride, so reload it before heading to the gate.
The official VISITKOREA transportation-card guide provides the current overview of T-money and other Korean transportation cards.
Where to Buy a T-money Card
Participating convenience stores are one of the easiest places to buy an ordinary physical T-money card. Availability, design and physical-card price can vary by location.
You may also encounter transportation-card sales locations, subway information centers, vending machines or tourist products that include a transportation-card function. A special tourist design is not required for normal subway and bus travel.
When asking at a staffed counter, you can show:
티머니 카드 있어요?
T-money kadeu isseoyo?
Do you have a T-money card?
Make sure you are buying a rechargeable transportation card rather than a single-journey subway ticket or a time-limited pass.
For more about store payment, opening hours and the difference between merchandise payment and transportation-card reloads, see our Korean convenience-store guide.
How to Reload an Ordinary Physical T-money Card
For a standard physical T-money reload, keeping Korean-won cash available remains the dependable approach for international visitors. Current Korea Tourism Organization guidance distinguishes ordinary prepaid transportation-card purchase and reload from newer ticket products that accept foreign-issued cards.
Reloading at a Convenience Store
- Give the T-money card to the cashier.
- Tell or show the cashier how much you want to add.
- Pay with Korean-won cash.
- Wait until the cashier confirms the reload.
- Take the card and any change before leaving.
티머니 만 원 충전해 주세요.
T-money man won chungjeonhae juseyo.
Please add KRW 10,000 to this T-money card.
Reloading at a Subway Station
Use a transportation-card reload machine or other supported machine and choose the available language option. Place the card on the indicated reader, select the amount, insert the supported payment and leave the card in place until the completion message appears.
Payment support can differ by machine and product. For an ordinary physical T-money balance, do not arrive assuming that an overseas credit card will work for the reload.
What Changed at Seoul Subway Machines in 2026?
On March 17, 2026, Seoul expanded international-card payment to 440 new transit ticket machines at 273 stations on Subway Lines 1–8. Eligible foreign-issued credit and debit cards can be used at supported machines for specific products including single-journey subway tickets and Climate Card short-term passes.
This does not mean that every ordinary physical T-money balance can now be reloaded with an overseas card.
| Product or Payment Method | What Travelers Should Know |
|---|---|
| Ordinary physical T-money | Keep Korean-won cash available for standard purchase and reload routes. |
| Climate Card short-term pass | Supported new machines can accept eligible international cards. |
| Single-journey subway ticket | Supported new machines can accept eligible international cards. |
| Foreign card tapped directly at a normal gate | Do not treat this as a Seoul-wide replacement for T-money. |
See the Seoul Metropolitan Government announcement on international-card ticket machines for the current scope.
If a foreign payment card fails outside the transportation system as well, our guide to what to do if your credit card does not work in Korea explains terminal, issuer and backup-payment checks.
How to Use T-money at a Subway Gate
- Take the card out before reaching the reader.
- Confirm that you are entering in the correct direction.
- Place the card close and flat on the reader.
- Wait for the beep, screen response or gate opening.
- Walk through without stopping inside the gate.
- At your destination, use the same card at the exit gate.
Do not swipe the card across the reader or wave it from a distance. A wallet containing several transit or contactless cards can also cause a reading problem, so remove the T-money card when necessary.
If the gate remains closed, step aside so other passengers can pass. Read the message, try one deliberate tap and use station staff or fare-adjustment equipment if the problem continues.
Always Use the Same Card to Enter and Exit
The fare system connects the entry and exit records. If you enter with one card and attempt to leave with another, the journey records cannot be matched correctly.
For normal subway travel, use one card per traveler. Each passenger needs an individual entry and exit record.
How to Use T-money on a Seoul Bus
On a typical Seoul city bus, board through the front door and tap the reader near the driver. Before your stop, press the stop bell and tap the reader near the exit before getting off.
- Check the bus number and direction before boarding.
- Have the T-money card ready.
- Tap once when boarding.
- Check for the normal confirmation sound or display.
- Press the stop bell before your destination.
- Tap the card again before leaving the bus.
The exit tap records the end of the ride and matters for distance-based fare calculation and eligible transfers.
If your problem is getting the correct bus to stop in the first place, see what to do when a Korean bus skips your stop.
How Seoul Transfer Discounts Work
Seoul’s integrated fare system can link eligible bus and subway journeys when the same transportation card is used correctly.
Current Seoul rules include:
- tap the card when getting off a bus
- begin the next eligible ride within 30 minutes
- the window extends to 60 minutes from 9 PM to 7 AM the next day
- up to four transfers can be linked, creating up to five boardings
- ordinary transfer treatment does not apply when simply reboarding the same bus route
A transfer discount does not necessarily make every next ride completely free. Differences in base fare and additional distance charges can still apply.
You can review the current rules on the Seoul Metropolitan Government transportation guide.
Can One Card Pay for Several People?
Multi-passenger payment can be possible on some buses when the passenger count is given to the driver before tapping, but the conditions are different from individual subway travel and can complicate transfers.
For tourists who will use both buses and subways, one card per traveler is the simplest setup.
Using T-money for Airport Transportation
Do not assume that every airport service uses the same T-money payment method.
| Airport Transportation | What to Know |
|---|---|
| AREX All-Stop Train | Compatible prepaid transportation cards can be used at the gates. |
| AREX Express Train | A separate Express Train ticket is required. |
| Airport limousine bus | Ticketing and payment depend on the route, direction and operator. |
| Taxi | Payment-card and transportation-card acceptance depends on the taxi and payment terminal. |
The official AREX All-Stop Train guide lists prepaid transportation cards as a boarding option. The AREX Express Train guide states that the nonstop service requires a separate ticket.
Airport Limousine Buses Need a Separate Check
Airport-bus procedures vary by route and direction. From Incheon Airport, bus tickets can be purchased through the airport’s bus ticket facilities, while some Seoul-to-airport services allow passengers to pay when boarding.
Do not assume that an ordinary T-money tap alone covers every airport limousine route. Check the specific operator and direction before traveling. Incheon Airport provides current Terminal 1 bus ticket information and separate information for Terminal 2.
Can You Tap a Foreign Visa or Mastercard Directly?
Do not rely on a normal foreign Visa, Mastercard or other overseas bank card as a universal replacement for T-money at Seoul subway gates and city-bus readers.
Keep these three situations separate:
- using an international card to buy a supported ticket at a vending machine
- using an international card to purchase or reload a specific pass
- tapping the international card itself directly on a transit reader
Support for one function does not prove that the other two are available.
What About Tmoney in Apple Wallet?
Tmoney is available as a supported transit card in Apple Wallet on eligible Apple devices. This is different from simply storing a normal foreign Visa or Mastercard in Apple Pay and tapping that bank card at a subway gate.
There is an important limitation for many short-term visitors: Apple’s current support guidance states that a South Korea-issued credit or debit card is required to purchase or top up a Tmoney card from Apple Wallet.
That means travelers who only have foreign-issued cards should not assume that digital Tmoney removes the need for another transportation-payment plan.
Review the current Apple transit-card guidance before relying on Wallet Tmoney. Our Apple Pay in Korea guide explains the difference between retail Apple Pay, Apple Wallet Tmoney, ticket-machine payments and direct transit-reader payments.
What the Reader Screen Shows
After a successful tap, the reader may briefly display the fare charged and remaining balance. The information can disappear quickly, so first confirm that the gate opens or the bus reader gives the normal response.
Check your balance before an important trip rather than waiting until you are at the final airport connection with too little stored value.
What to Do When the Card Does Not Work
| Problem | What to Do |
|---|---|
| The reader does not react | Move the card closer and remove it from a wallet containing other contactless cards. |
| The subway gate stays closed | Step aside, read the message and try one deliberate tap. |
| The balance is too low | Use a supported reload or fare-adjustment machine, or ask station staff. |
| Entry and exit records do not match | Show the card to station staff instead of switching to another card. |
| The bus reader shows an error | Keep the card visible and ask the driver before repeatedly tapping. |
| The card appears damaged | Ask at a supported Tmoney service or sales location. |

Refunding the Remaining Balance
Eligible T-money balances can be refunded at supported service locations. The physical card purchase price itself is not refundable, and a service fee may apply.
Refund locations and limits depend on the remaining balance and service point, so check the current Tmoney guidance before relying on one particular convenience store or station counter.
The official Tmoney foreigner guide is linked from the current VISITKOREA transportation-card page and should be checked shortly before requesting a refund.
Common First-Time Mistakes
- Buying the physical card but forgetting to add transportation balance.
- Trying to reload an ordinary physical T-money card with a foreign card without carrying Korean-won cash.
- Assuming the 2026 international-card vending machines reload every T-money product.
- Swiping or waving the card rather than placing it close to the reader.
- Using different cards for subway entry and exit.
- Forgetting to tap when leaving a Seoul bus.
- Assuming every airport service accepts an ordinary T-money tap.
- Assuming a foreign card that works at a ticket machine also works directly at every transit gate.
- Assuming Apple Wallet Tmoney can be funded with any foreign credit card.
- Sharing one card among several subway passengers.
- Changing cards during an eligible transfer.
- Waiting until the airport trip to check the remaining balance.
Frequently Asked Questions
Can I top up an ordinary T-money card with a foreign credit card?
Do not rely on it. Current tourism guidance directs international visitors to keep Korean-won cash available for ordinary prepaid T-money purchase and reload. International-card support at new subway machines applies to specific ticket and pass products rather than automatically to every ordinary T-money reload.
Can one T-money card be used for two people on the subway?
For normal subway travel, use one card per passenger. Each person needs an individual entry and exit record.
Do I need to tap when leaving a Seoul bus?
Yes. The exit tap records the end of the ride and is important for correct distance-based fare calculation and eligible transfers.
Can I use T-money on the AREX Express Train?
The AREX All-Stop Train accepts compatible prepaid transportation cards at the gates. The Express Train is a separate service and requires its own ticket.
Can I tap my Visa or Mastercard directly at a Seoul subway gate?
Do not depend on that as a Seoul-wide payment method. International-card payment at a ticket machine is different from directly tapping the foreign bank card at a subway or bus reader.
Can I use Tmoney in Apple Wallet with a foreign credit card?
Tmoney itself is supported in Apple Wallet, but Apple’s current guidance states that purchasing or topping up a Tmoney card from Wallet requires a South Korea-issued credit or debit card.
How long do I have to transfer?
Current Seoul rules generally provide 30 minutes after tapping off the previous ride, extended to 60 minutes from 9 PM to 7 AM the next day. Route and transfer conditions still apply.
Can I refund the remaining T-money balance?
Eligible balances can be refunded through supported service locations, but the card purchase price is not refunded and service fees or location-specific balance limits may apply. Check the current Tmoney guide before requesting the refund.
Final Takeaway
Using T-money in Seoul becomes simple once four habits are automatic: keep the card ready, tap it close to the reader, use the same card throughout each journey and tap when leaving a bus.
Keep Korean-won cash available for ordinary physical-card reloads, check your balance before an important trip and distinguish T-money from Climate Card passes, single-journey tickets, AREX Express tickets, Apple Wallet Tmoney and international-card ticket-machine payments.
The most important 2026 distinction is that a foreign card working at a new ticket machine does not automatically mean that the same card can reload an ordinary physical T-money balance or be tapped directly at every Seoul transit reader.
