In South Korea, public transportation (such as buses, subways, and even some taxis) is most easily paid for with a transportation card โ a contactless smart card you tap to pay the fare. The most common card is called T-money, though there are others such as Cashbee.ย
There are two main ways foreigners can pay for transit:
Prepaid transportation card โ like a T-money card you charge with money before use (most common for visitors).ย
Post-paid transportation function on a Korean bank card โ some Korean debit or credit cards have an integrated transportation payment feature (this is what is meant by โpostpaidโ).ย
However, note that as of 2025 many overseas credit cards cannot yet be used directly as postpaid transit cards because the payment system is based on Koreaโs own transportation card network โ so most foreign visitors still need a T-money-style card.
1. Using a Postpaid Transportation Card (Korean Credit/Debit Card with Transit Function)
Some Korean credit or debit cards can act as a postpaid transit card โ meaning you do not have to pre-load money before riding. Instead:
โ
Tap your card at the gate or bus reader
โ
The transit fare is charged to your card account later, like a normal credit card payment
โ
No need to top up first
This is super convenient, but only works if your card was issued in Korea with this transit payment feature enabled by the bank.ย
For most international visitors, this option is not yet available with foreign credit cards, although local governments are gradually introducing open-loop systems to allow this in the future.
2. Using a Prepaid Transportation Card (T-money or Similar)
For most travelers, the easiest way to pay for buses, subways, and taxis is to use a prepaid card like T-money:
๐น Buy a T-money card at a convenience store or metro station.
๐น Top up (add money) using cash at a machine, convenience store, or ticket kiosk.
๐น Tap the card on the reader when boarding and exiting public transport.ย
This method is the standard way most Koreans and visitors pay for transit โ and it works almost everywhere in Korea.
ย Tips for Transit Card Use
๐ Where it works: Buses, subways, taxis, and even some bikes or convenience store purchases.
๐ How to pay: Just tap your card on the reader at the turnstiles or bus terminals โ the cost is automatically deducted.
๐ Balance checks: You can check remaining balance when you tap, at machines in stations, or at convenience stores.
๐ Transfers: If you transfer between bus and subway within a certain time, you may get a discount on the next ride.
๐ Cashless buses: Many buses no longer accept cash at all, so having a card is essential.
