A T-money card is one of the most convenient ways to use buses and subways in Korea. Instead of purchasing a ticket every time you travel, you can simply tap the card on the reader when entering and leaving public transportation.
T-money is a prepaid transportation card that can also be used at participating taxis, convenience stores, vending machines, and other affiliated merchants.
Before using T-money for the first time, you should decide:
Whether to purchase a physical T-money card
Whether to use Mobile T-money on a smartphone
Whether to use a prepaid balance or a postpaid transportation service
A physical card works regardless of your smartphone model and is especially convenient for travelers. Mobile T-money allows you to use public transportation without carrying a separate card.
This guide explains where to purchase a T-money card, how to recharge it, how to use Mobile T-money, how to register a child or youth discount, and how to check or refund the remaining balance.

1. T-money Card Types and Where to Buy Them

Physical T-money Cards

The most common type is a prepaid plastic T-money card. You purchase the card first and then load money onto it before using public transportation.

T-money cards are commonly available at:

GS25
CU
7-Eleven
Emart24
Convenience stores displaying the T-money logo
Customer service centers or vending machines at subway stations
Selected street kiosks
Transportation card shops at Incheon International Airport
Official online T-money stores

Not every store carries the same designs. In addition to standard cards, you may find character cards, keychain-style cards, and limited-edition designs. Prices may vary depending on the card design.

When visiting a convenience store, you can simply ask:

“Do you have a T-money transportation card?”

The purchase price of the card and the rechargeable balance are separate. After buying the card, you must add money before using it on a bus or subway.

The card purchase price is generally not refundable, even when the remaining transportation balance is refunded. A basic card is usually the most economical choice unless you specifically want a character or limited-edition design.

Standard Cards and Discount Cards

Adults can purchase a standard T-money card and use it immediately after adding money.

Children and teenagers must register their date of birth to receive discounted public transportation fares. Simply purchasing a card does not automatically activate the child or youth fare.

Discount registration may be available:

At participating convenience stores when purchasing the card
Through the official T-money website
At selected transportation service centers

The card must be registered using the actual passenger’s date of birth. Using another person’s discounted card may be treated as fare evasion.

2. How to Recharge a Physical T-money Card

Physical T-money cards can be recharged at convenience stores, subway stations, selected street kiosks, and participating ATMs.

According to the official T-money guidance, the minimum recharge amount is generally 1,000 won, while the maximum balance that can be stored on one card is 500,000 won. Recharge limits may vary depending on the location or payment method.

Recharging at a Convenience Store

Recharging a T-money card at a convenience store is simple.

Tell the cashier that you would like to recharge your T-money card.
Place the card on the payment terminal.
Tell the cashier the amount you want to add.
Complete the payment.
Check that the new balance has been correctly added.

Cash is the safest payment method when recharging a physical card at a convenience store. Credit cards, debit cards, and mobile payment methods may not be accepted for transportation card recharges at every store.

It is a good idea to keep the receipt until you confirm that the recharge was successful. The receipt can help verify the transaction time and amount if an error occurs.

Recharging at a Subway Station

You can recharge your card using a transportation card machine or by visiting the subway station customer service center.

The usual process at a machine is:

Select the transportation card recharge option.
Place the T-money card on the designated card reader.
Choose the recharge amount.
Insert cash as instructed.
Wait until the recharge is completed.
Check the final balance before removing the card.

Do not remove the card before the machine displays a completion message. Removing it too early may interrupt the recharge process.

Recharging a Physical Card with a Smartphone

Some NFC-enabled smartphones allow users to check and recharge the balance of a physical T-money card through the Mobile T-money app.

Open the app, select the physical T-money card recharge option, and place the card against the NFC reader area on the back of the smartphone.

Depending on the device and app settings, available payment methods may include:

Bank account transfer
Credit card
Debit card
Other supported mobile payment methods

Available functions may vary depending on the smartphone model, operating system, NFC compatibility, and payment provider.

Important Recharge Tips

Confirm the recharge amount before making payment.
Do not remove the card until the recharge is complete.
Keep the receipt when recharging at a convenience store.
Avoid storing an unnecessarily large balance on the card.
Remove other transportation or credit cards from your wallet before tapping.
Place only one card on the reader to prevent card recognition errors.

3. How to Set Up and Recharge Mobile T-money

Mobile T-money allows a compatible smartphone to function as a transportation card. You can tap the back of your phone on a bus or subway reader instead of using a physical card.

Mobile T-money for Android

On compatible Android smartphones, users can install the Mobile T-money app and select either a prepaid or postpaid transportation option.

A prepaid card requires users to add money before traveling. Recharge options may include:

Bank account transfer
Credit card
Debit card
Mobile phone billing
Other payment methods supported by the app

An automatic recharge function may also be available. This feature automatically adds a selected amount when the balance falls below a specified level.

A postpaid transportation service allows public transportation fares to be charged later to a registered credit card. Transportation discounts depend on the individual credit card product and its terms.

A thick or metal smartphone case may interfere with NFC recognition. When tapping does not work properly, remove the case or check the location of the smartphone’s NFC antenna.

T-money on iPhone and Apple Watch

T-money can also be added to Apple Wallet on compatible iPhone and Apple Watch devices.

The general setup process is:

Open the Apple Wallet app.
Tap the Add button.
Select “Transit Card.”
Choose T-money.
Enter the amount you want to add.
Complete payment verification with a card registered in Apple Pay.
Confirm that Express Mode is enabled.

With Express Mode, you can tap your iPhone or Apple Watch on a transportation reader without opening an app or completing Face ID authentication every time.

Compatible devices and operating system requirements may apply. Check the eligibility information displayed during setup before issuing the card.

To recharge T-money in Apple Wallet:

Open Apple Wallet.
Select the T-money card.
Tap the recharge option.
Enter the amount.
Select a payment card.
Complete authentication.

The remaining balance and transaction history can also be viewed in Apple Wallet.

Physical T-money or Mobile T-money?

A physical card may be more suitable when:

You want to use T-money regardless of your smartphone model.
You are purchasing a card for a child or family member.
You do not want to depend on smartphone battery life.
You are visiting Korea for a short trip.
You prefer a simple prepaid transportation card.

You want to review transportation transaction history on your phone.

4. Discount Registration, Balance Checks, and Refunds

Child and Youth Discount Registration

Children and teenagers must register their T-money card to receive discounted public transportation fares.

Without registration, the adult fare may be charged even if the passenger qualifies for a child or youth discount.

The general online registration process is:

Visit the T-money Card & Pay website.
Open the card registration menu.
Select child or youth discount registration.
Enter the card number and date of birth.
Review the information and complete registration.

In some cases, discount registration can be completed without creating a website account. The card number and passenger’s date of birth may be sufficient.

The registered information must belong to the person who will actually use the card.

How to Check the T-money Balance

You can check the remaining balance using several methods:

Check the screen after tapping on a bus or subway reader.
Ask the cashier at a convenience store.
Use a transportation card machine at a subway station.
Use the Mobile T-money app on an NFC-enabled smartphone.
Open the T-money card in Apple Wallet.
Check the balance during a recharge transaction.

When using a physical card with a smartphone, place the card against the NFC reader area on the back of the phone.

How to Refund the Remaining Balance

The remaining balance on a functioning T-money card can usually be refunded at designated convenience stores, subway station customer service centers, and participating ATMs.

However, refund limits and procedures differ depending on the location.

Important points include:

A refund fee may be deducted.
The physical card purchase price is generally not refundable.
Large refunds may require identification.
A Korean bank account may be required for certain refund methods.
Damaged cards require a different refund procedure.
Some refund locations have lower maximum refund limits than others.

If the card is damaged or no longer recognized by transportation readers, follow the damaged-card refund instructions on the official T-money website.

How to Reduce the Risk of Losing Your Balance

A standard prepaid physical card may not allow you to recover the balance after it is lost. For this reason, avoid keeping an unnecessarily large amount on the card.

You may also consider:

Using automatic recharge with a small threshold
Registering eligible mobile transportation services
Checking whether your service includes balance protection
Keeping the card in a separate cardholder
Saving the card number when registration or protection services are available

To recharge using a credit or debit card, you may find it more convenient to use:

The Mobile T-money app on a compatible NFC smartphone

Tap the card when boarding a bus.
Tap again when getting off the bus.
