Public transportation in Korea is generally fast, frequent, and well connected. In major cities, you can reach most residential areas, business districts, tourist attractions, and shopping areas by combining the subway and local buses.

The network itself is convenient, but the payment system may feel unfamiliar when you first arrive.

Table of Contents

You may hear terms such as:

T-money card
Transportation card
Base fare
Distance-based fare
Bus transfer
Tap in and tap out

Fortunately, the basic system is logical.

Buy a rechargeable transportation card, add Korean won to its balance, and tap the same card whenever you enter and leave the transportation system.

T-money is one of Korea’s most widely used prepaid transportation cards. It can be used on many local buses, subways, metropolitan railway services, taxis, and participating payment terminals.

Quick Answer: How Do You Use T-money in Korea?

For most travelers and new residents, the process is:

Buy one T-money card per person.
Add Korean won to the card.
Tap the card when entering a subway station.
Tap the same card when leaving the subway.
Tap when boarding a bus.
Tap again before getting off the bus.
Use the same card when transferring between eligible buses and subways.
Keep enough balance for your next journey.

A physical T-money card is usually the simplest option for someone who has just arrived in Korea.

What Is a T-money Card?

A T-money card is a stored-value transportation card.

“Stored value” means that you load money onto the card before using it. Each time you ride a bus or subway, the system deducts the appropriate fare from the remaining balance.

A standard physical card works independently from your normal bank account. This makes it practical for:

Tourists
International students
Foreign workers
Short-term visitors
Newly arrived residents
People without a Korean credit card

A basic T-money card does not work like an unlimited travel pass. You pay for each journey from the stored balance.

Where Can You Use T-money?

T-money is widely accepted on:

City buses
Local and metropolitan subways
Many metropolitan railway services
Some airport railway services
Many taxis
Participating convenience stores and businesses

However, not every form of transportation uses the normal T-money system.

You may need a separate ticket for:

KTX and other reserved intercity trains
Express intercity buses
Some airport limousine buses
Privately operated shuttle buses
Tourist buses
Premium or reserved transportation services

Look for the T-money logo near the card reader or ticket machine when you are unsure.

Where to Buy a T-money Card

The easiest place to buy a T-money card is usually a convenience store.

Common sales locations include:

CU
GS25
7-Eleven
Emart24
Storyway stores near railway stations
Selected subway information centers
T-money sales machines and service locations

You can ask the cashier:

“T-money card, please.”

In Korean:

티머니 카드 있어요?
T-money kadeu isseoyo?
“Do you have a T-money card?”

Card prices vary depending on the design. A basic plastic card is usually cheaper than a character card, key ring, or souvenir-style card.

The Card Price and Transportation Balance Are Separate

Buying the physical card does not necessarily mean it already contains transportation credit.

You may need to pay for:

The physical card
The amount you want to load onto it

For example, after buying the card, ask the cashier to add KRW 20,000.

How to Recharge a T-money Card

You can normally recharge a T-money card at:

Convenience-store counters
Subway ticket and recharge machines
Subway information centers
Authorized T-money service locations

At a convenience store, give the cashier your card and say how much you want to add.

For example:

이만 원 충전해 주세요.
I-man won chungjeon hae juseyo.
“Please recharge 20,000 won.”

T-money’s official foreign-user guide states that standard cash top-ups are available in KRW 1,000 units. The listed top-up range is KRW 1,000 to KRW 90,000 per transaction, and the total card balance may not exceed KRW 500,000.

Do You Need Cash to Recharge T-money?

Korean won cash remains the most dependable way to recharge a standard physical T-money card.

Convenience stores generally process ordinary T-money recharges with cash. Many subway machines also accept cash for standard transportation-card top-ups.

Some newer machines support additional payment methods, but the accepted options depend on:

The station
The machine
The card product
Whether the payment card was issued in Korea or overseas

Important 2026 Update for International Credit Cards

Starting March 17, 2026, 440 new ticket machines at 273 Seoul subway stations on Lines 1–8 began accepting internationally issued cards such as Visa and Mastercard.

However, this international-card support initially applies to:

Purchasing single-journey subway tickets
Purchasing Climate Card short-term passes
Recharging Climate Card short-term passes

It does not mean that every standard T-money card can be recharged with a foreign credit card at every subway machine.

The Seoul Metropolitan Government also states that an average service fee of approximately 3.7% applies when using an internationally issued card through these machines.

For that reason, carrying a small amount of Korean won is still useful.

How to Use T-money on the Subway

Using a Korean subway with T-money follows the same basic process in most cities.

Step 1: Find the Correct Station and Line

Korean subway lines are usually identified by:

A line number
A line name
A line color
Station names
Station numbers

Large subway systems operate in areas including:

Seoul and the surrounding metropolitan region
Busan
Daegu
Daejeon
Gwangju

The Seoul metropolitan network also extends into Incheon and Gyeonggi Province.

Use Naver Map or KakaoMap to check:

The best route
Required transfers
Estimated travel time
Train direction
Station exits
Bus and subway arrival information

Both apps provide Korean route information, and multilingual interfaces are available. Real-time route information is often more complete than what visitors find through Google Maps in Korea.

Step 2: Tap Your Card at the Entrance Gate

Place the T-money card flat against the card reader.

Wait for:

A confirmation sound
The gate to open
The screen to display information

The screen may show the fare deducted, the remaining balance, or both.

Do not wave the card past the reader too quickly. Hold it close until the system recognizes it.

Step 3: Check the Direction Before Entering the Platform

Before going down to the platform, confirm that you are traveling in the correct direction.

Subway signs often show:

The next station
Several upcoming stations
The terminal station
Transfer lines
Exit directions

The terminal station is especially useful because two trains on the same line may travel in opposite directions.

Step 4: Follow the Transfer Signs

When changing subway lines, follow the signs marked Transfer.

You normally remain inside the paid area while moving between ordinary subway lines. The connected journey is then calculated when you tap out at your final destination.

Additional charges may apply when:

You travel a longer distance
You use a premium service
You enter a special operating section
The route has a separate surcharge

Step 5: Tap Out at Your Destination

Use the same T-money card at the exit gate.

The system uses your entry and exit records to calculate the correct fare.

Your final charge may depend on:

Passenger category
Transportation type
Total distance
Transfer history
Special route charges

If your balance is too low to leave the station, use a nearby recharge or fare-adjustment machine. You can also ask station staff for help.

Why Must You Use the Same Card?

The transportation system connects the entrance and exit records through the card number.

For example:

Card A enters the subway.
Card B has no matching entrance record.
Card A must therefore be used to exit.

Do not enter with one card and attempt to leave with another.

How to Use T-money on a Korean Bus

Bus payment is simple, although finding the correct route may take more practice than using the subway.

Step 1: Confirm the Bus Number and Direction

Do not board a bus only because the number looks correct.

Check:

The bus number
The destination
The direction
The stop name
Whether the bus is local, express, metropolitan, or late-night

Some routes use similar numbers but travel in different directions.

Naver Map and KakaoMap can display estimated arrival times, current bus locations, stop sequences, and transfer instructions.

Step 2: Board Through the Front Door

Most Korean city buses expect passengers to board through the front door.

Tap your T-money card on the reader near the driver.

Wait for the confirmation sound before moving into the bus.

Step 3: Follow the Stop Announcements

Bus stop information may appear through:

Korean announcements
English announcements on some routes
A digital screen
Your navigation app

Using a map app is helpful because announcements can be difficult to hear when the bus is crowded.

Step 4: Press the Stop Button

Press one of the stop buttons before the bus reaches your destination.

The buttons are usually attached to walls, poles, or the area near the windows.

Do not wait until the bus has already passed your stop.

Step 5: Tap Before Getting Off

Tap your card on the reader near the exit door before leaving.

This second tap is important because it:

Records the end of the bus journey
Helps calculate distance-based charges
Preserves eligible transfer discounts
Closes the current trip record

Seoul’s official transportation guidance instructs passengers to tap both when boarding and when getting off.

Engineer Dad’s rule: Treat every bus ride like opening and closing a digital transaction. Tap once to start the journey and once to finish it.

How Bus and Subway Transfers Work

A transfer means changing from one eligible public transportation service to another as part of a connected journey.

Possible combinations include:

Bus to bus
Bus to subway
Subway to bus
Subway line to subway line

A transfer discount does not necessarily mean that the second ride is completely free.

The system may still charge:

Additional distance fare
The difference between two base fares
A special-route surcharge
A new base fare when transfer conditions are not met

Seoul Metropolitan Transfer Rules

In the Seoul metropolitan integrated-fare system:

You must use a transportation card.
You must tap when getting off a bus.
The next eligible ride must normally begin within 30 minutes.
The transfer window is extended to 60 minutes from 9:00 p.m. to 7:00 a.m.
Up to four transfers are recognized, allowing up to five connected boardings.
Reboarding the same vehicle or the same bus route does not receive the normal transfer treatment.

Transfer rules can differ in Busan, Daegu, Daejeon, Gwangju, Jeju, and other regional systems.

Check the local operator’s rules when traveling outside the Seoul metropolitan area.

One Transportation Card per Person Is Best

On some buses, one card can be used to pay for several people if you tell the driver the number of passengers before tapping.

However, this is not the easiest option for foreign visitors because:

The driver must manually set the number of passengers.
The same number of passengers may need to transfer together.
Subway transfers are not supported under Seoul’s multi-passenger arrangement.
Entry and exit records become more complicated.

Seoul’s official guidance states that subway transfer discounts do not apply to multi-passenger bus payments.

For ordinary travel:

Use one transportation card per person.

How Much Does Public Transportation Cost in Korea?

Public transportation fares vary by:

City
Region
Bus category
Subway operator
Distance
Passenger age
Special route

Therefore, there is no single nationwide bus or subway fare.

Seoul Adult Fare Examples

The following standard adult fares were listed by the Seoul Metropolitan Government when this article was reviewed:

Transportation Type	Adult Fare
Standard Seoul subway with a transportation card	KRW 1,550
Seoul subway single-journey fare	KRW 1,650
Refundable single-journey card deposit	KRW 500
Standard Seoul trunk or branch bus	KRW 1,500

The Seoul subway card fare increased to KRW 1,550 on June 28, 2025. Longer journeys may include additional distance charges.

Express buses, late-night buses, metropolitan buses, and special services may cost more.

What Is a Single-Journey Subway Ticket?

A single-journey ticket is an alternative for someone who does not have a transportation card.

To use one in Seoul:

Find a subway ticket machine.
Select your preferred language.
Choose your destination.
Pay the fare and deposit.
Use the ticket to enter the subway.
Use it again to leave at your destination.
Insert the used ticket into a deposit-refund machine.

The standard adult single-journey fare is KRW 100 higher than the transportation-card fare. A refundable KRW 500 deposit is also collected for the reusable ticket card.

A single-journey ticket:

Works for the subway journey
Does not function as a normal bus transportation card
Is less convenient for repeated rides
Does not provide the same bus-and-subway transfer experience as T-money

T-money is usually more practical when you plan to use transportation more than once.

Which Transportation Card Should You Choose?

Several transportation-card products are available in Korea.

Card	Best For	Main Feature
T-money	Most tourists and residents	Simple pay-per-ride transportation
EZL	Travelers who find it more convenient to buy	Similar prepaid transportation function
WOWPASS	International visitors who also need payment and currency services	Transportation, prepaid payment, and foreign-currency services
Climate Card	Frequent travel within its covered Seoul network	Unlimited travel during the selected pass period

T-money

T-money is usually the easiest general-purpose choice.

It is suitable for:

Pay-per-ride transportation
Bus and subway transfers
Travel in multiple Korean cities
Visitors who do not need an unlimited Seoul pass
Residents who want a standard rechargeable card

EZL

EZL is another rechargeable transportation card.

For most ordinary users, the process is similar to T-money:

Buy the card.
Add money.
Tap when using transportation.

Acceptance is broad, but individual merchant and transportation coverage may differ.

WOWPASS

WOWPASS is designed primarily for international visitors.

It combines several functions in one card and app:

Foreign-currency exchange services
A prepaid payment or debit-card function
A Korean transportation-card function
Balance management through the app or supported kiosks

This can be convenient for a traveler who wants one physical card for both transportation and ordinary purchases.

However, the transportation balance and the general WOWPASS payment balance are separate.

Adding money to the payment side does not automatically mean that the transportation side has enough fare credit. Make sure you check and recharge the transportation balance separately.

WOWPASS may suit you when:

You are visiting Korea for a short trip.
You want a prepaid shopping card.
You want to exchange supported foreign currencies.
You prefer managing spending through an app.

A standard T-money card is simpler when you only need transportation.

Seoul Climate Card

The Climate Card is an unlimited-use transportation pass for eligible transportation within its covered Seoul network.

It is different from T-money because:

T-money deducts money for each journey.
The Climate Card allows unlimited eligible rides during its validity period.

Short-term Climate Card options include:

Pass	Price
1-day pass	KRW 5,000
2-day pass	KRW 8,000
3-day pass	KRW 10,000
5-day pass	KRW 15,000
7-day pass	KRW 20,000

A physical Climate Card costs an additional KRW 3,000.

Short-term passes do not include Seoul Bike Ttareungi or the Hangang Bus. The validity period starts on the date the short-term pass is charged, and short-term passes cannot normally be charged in advance for a later start date.

Check the Climate Card Coverage Carefully

The Climate Card does not cover every train, bus, airport route, or destination in the wider Seoul metropolitan region.

Coverage generally focuses on:

Designated Seoul subway sections
Seoul-licensed city and village buses
Other specifically included services

Some routes extending into Gyeonggi Province or Incheon may be outside the coverage area.

Check both your boarding and exit stations before deciding that the Climate Card is cheaper than T-money.

Can You Tap a Foreign Credit Card Directly at the Subway Gate?

Do not assume that an overseas Visa or Mastercard can be tapped directly at every Korean subway gate or bus reader.

The March 2026 expansion allows foreign cards to be used at selected Seoul ticket machines for specific products.

That is different from using a foreign bank card as a general contactless transportation card at the gate.

The supported machine transactions initially include:

Climate Card short-term passes
Climate Card short-term recharges
Single-journey subway tickets

A physical T-money card remains the safer general option for ordinary pay-per-ride bus and subway travel.

How to Check Your T-money Balance

Your remaining balance is often displayed when you tap the card.

You can also ask to check it at:

A convenience store
A subway recharge machine
A subway information center
A compatible mobile application or device

Keep enough balance before beginning a journey, especially when:

Traveling late at night
Boarding a bus away from a subway station
Visiting a smaller city
Going directly to an airport or terminal

Can You Refund the Remaining T-money Balance?

You can request a refund at an eligible T-money sales or service location.

According to T-money’s official foreign-user guide:

Refunds are normally paid in Korean won.
The original physical card price is not refunded.
A KRW 500 service fee normally applies.
Partial refunds are limited to designated T-money service locations.
Larger or unusual refunds may require a designated service center.

Refund procedures may vary depending on the card type, balance, and location.

Ask the staff before processing the refund if you plan to keep the physical card as a souvenir.

Common T-money Mistakes

1. Forgetting to Tap When Getting Off a Bus

This may affect:

Distance calculation
Transfer eligibility
The next fare charged

Make tapping out a habit even when you are not planning an immediate transfer.

2. Using Different Cards to Enter and Exit

The card used to enter the subway must also be used to exit.

Keep your transportation card in a consistent location so you do not accidentally switch cards.

3. Tapping a Wallet Containing Several Cards

A wallet containing multiple contactless cards may cause:

A card collision error
The wrong card to be charged
No card to be recognized

Remove the T-money card and tap it separately.

4. Assuming Every Transfer Is Completely Free

A transfer discount does not guarantee that the next ride costs KRW 0.

You may still pay:

Additional distance charges
The difference between route fares
A premium-route surcharge

5. Reboarding the Same Bus Route

In Seoul, reboarding the same bus or bus route is generally not recognized as a discounted transfer.

A new base fare may be charged.

6. Trying to Use a Subway Single Ticket on a Bus

A single-journey subway ticket is not a general transportation card.

It cannot replace T-money for normal bus travel.

7. Assuming the Physical Card Price Includes Fare Credit

The card itself and its usable balance are separate.

After buying the card, check that money has actually been loaded.

8. Relying Only on Google Maps

Google Maps can be useful for identifying places, but public transportation directions in Korea may be easier to follow with:

Naver Map
KakaoMap

These Korean services provide detailed local route, stop, exit, and arrival information.

9. Confusing a WOWPASS Payment Balance with Its Transportation Balance

WOWPASS combines several functions, but its payment and transportation balances are separate.

Check the transportation balance before boarding a bus or entering the subway.

10. Buying a Climate Card Without Checking the Coverage Area

An unlimited pass is not automatically the cheapest option.

T-money may be better when:

You take only a few rides.
You travel outside Seoul frequently.
Your destination is outside the Climate Card network.
Your airport route is not fully covered.

Basic Public Transportation Etiquette

A few local habits will make your journey more comfortable.

Let passengers exit the subway before entering.
Stand to the side of the subway doors while waiting.
Keep phone calls brief and quiet.
Move farther inside a crowded bus.
Avoid blocking the entrance or exit.
Keep bags off seats during busy periods.
Prepare to leave before the bus reaches your stop.
Have your transportation card ready before reaching the reader.
Use priority seats considerately.

Priority seating is intended mainly for:

Older passengers
Pregnant passengers
Passengers with disabilities
Adults traveling with very young children
People who have difficulty standing safely

On crowded transportation, watch how other passengers line up and move. The normal flow becomes easy to understand after a few journeys.

First-Day Transportation Checklist

Before taking your first bus or subway ride in Korea, prepare:

One transportation card per person
KRW 10,000 to KRW 20,000 in card balance
A small amount of Korean won cash
Naver Map or KakaoMap
Your destination written in Korean
The correct subway exit number
The correct bus-stop name
Enough phone battery for navigation

Once these items are ready, public transportation becomes much easier.

Frequently Asked Questions

Can foreigners buy a T-money card in Korea?

Yes. Foreign visitors can buy a standard prepaid T-money card at convenience stores and other authorized sales locations.

A Korean bank account is not required for an ordinary prepaid card.

Can I use T-money on both buses and subways?

Yes. T-money is widely accepted on local buses, subways, and metropolitan transportation networks.

Special shuttles, reserved trains, intercity services, and some airport buses may require separate tickets.

Do I tap T-money when getting off a bus?

Yes.

Tapping when getting off:

Records the end of your journey
Supports correct distance calculation
Preserves eligible transfer discounts

Do I need to tap out of the subway?

Yes.

Use the same card at both the entrance and exit gates.

Can two people share one T-money card?

It may be possible on some buses if you tell the driver the number of passengers before tapping.

However, subway use and transfer discounts become complicated. Seoul does not provide a subway transfer discount for multi-passenger bus payment arrangements.

One card per person is strongly recommended.

Can I recharge T-money with a foreign credit card?

Do not depend on it.

Korean won cash remains the standard and most reliable method for recharging an ordinary physical T-money card.

Selected Seoul subway machines accept foreign cards for single-journey tickets and Climate Card short-term products, but this does not guarantee foreign-card support for ordinary T-money recharges.

Can I use Apple Pay or Google Pay instead of T-money?

Do not assume that an overseas mobile wallet will work directly on Korean bus and subway readers.

Compatibility depends on:

The phone
The operating system
The mobile transportation-card service
The card issuer
Device and regional settings

A physical T-money card is usually the simplest choice for a newly arrived traveler.

Can I use T-money outside Seoul?

Yes. T-money is widely accepted on many regional transportation networks.

However, fares, transfer windows, and regional rules can differ. Check local information when traveling in Busan, Daegu, Daejeon, Gwangju, Jeju, or other areas.

Does a T-money card expire?

A normal reusable T-money card is not a one-day or monthly pass. Its stored balance remains available subject to the card provider’s terms and the physical condition of the card.

Products such as the Climate Card have separate validity periods.

What happens if my balance is too low?

At a subway station, use a recharge or fare-adjustment machine near the gates.

Before boarding a bus, recharge the card at a convenience store or subway station. A bus driver generally cannot recharge the card for you.

Is T-money cheaper than buying individual subway tickets?

In Seoul, the standard adult transportation-card subway fare is KRW 100 lower than the equivalent single-journey fare.

T-money also allows integrated bus and subway transfer discounts when the transfer conditions are met.

Is the Climate Card always cheaper than T-money?

No.

The Climate Card is more likely to save money when you:

Take many eligible rides in Seoul
Remain within its coverage area
Use transportation repeatedly during the pass period

T-money may be better for light travel or trips outside the Climate Card network.

Is WOWPASS better than T-money?

It depends on what you need.

Choose T-money when you mainly need a simple transportation card.

Consider WOWPASS when you also want:

A prepaid card for shopping
Foreign-currency exchange services
App-based spending management

Remember that the WOWPASS payment and transportation balances are separate.

Final Summary

For most foreigners, the easiest way to use public transportation in Korea is:

Buy one physical T-money card per person.
Add Korean won to the card.
Tap when entering and leaving the subway.
Tap when boarding and getting off a bus.
Use the same card throughout a connected journey.
Complete an eligible Seoul transfer within 30 minutes, or within 60 minutes from 9:00 p.m. to 7:00 a.m.
Keep some cash available for standard T-money recharges.
Use Naver Map or KakaoMap for route planning.
Check regional rules when traveling outside Seoul.
Compare T-money with the Climate Card before buying an unlimited pass.

The system may look complicated at first, but its logic is consistent.

Every tap tells the transportation network where a journey begins, where it ends, and whether the next ride is part of the same connected trip.

After a few rides, using buses, subways, and T-money usually becomes one of the easiest parts of traveling or living in Korea.
