Getting Your T-money Card

The T-money card is your key to Seoul's transit system. It works on all subways, buses, and even taxis.

Where to buy:

• Any convenience store (CU, GS25, 7-Eleven, Emart24) — just ask for "T-money"
• Vending machines inside subway stations
• Incheon Airport arrival hall convenience stores

Cost: ₩2,500 for the card itself (non-refundable), then load money onto it.

How to recharge:

• Convenience store counter — hand your card and cash to the cashier
• Subway station recharge machines — accept cash and some accept cards
• Load ₩10,000–20,000 to start; you can always add more

Why T-money beats single tickets:

• ₩100 discount per ride (₩1,250 vs ₩1,350)
• Free transfers between subway and bus within 30 minutes
• Works on taxis — just tap on the reader
• No need to buy a ticket every time

Tip: At the end of your trip, you can get a partial refund of your remaining balance (minus ₩500 processing fee) at any convenience store. Or just keep the card for your next visit — T-money cards don't expire.

Reading the Subway Map

Seoul's subway lines are color-coded and numbered, making navigation straightforward even without Korean.

Station signage is in Korean, English, Chinese, and Japanese. Platform screens show the next train's destination and arrival time in real-time.

Useful Apps for the Subway

• Naver Map: Includes subway routing with exit number recommendations and walking directions from the exit to your destination.
• KakaoMap: Similar to Naver Map with subway integration.

How to plan a route:

1. Open Subway Korea → tap your starting station → tap your destination
2. The app shows: fastest route, number of transfers, total time, fare, and which car to board for the fastest transfer
3. "Which car to board" is a game-changer — it tells you to board car #4 so you exit right in front of the transfer escalator

Subway Etiquette

A few unwritten rules that locals follow:

• Priority seats (at the end of each car, marked in a different color) are reserved for elderly, pregnant, and disabled passengers. Even if the train is packed and these seats are empty, Koreans will not sit in them.
• Keep quiet. Koreans rarely talk loudly on the subway. Phone calls are kept short and quiet.
• Stand on the right on escalators to let people walk on the left.
• Let passengers exit first before boarding.
• Eating and drinking is not allowed on the subway, though water is generally fine.
• Backpacks: In crowded trains, move your backpack to your front or place it between your feet.

Late Night Options

Missed the last train? Don't panic:

• Night buses (올빼미버스): Seoul operates late-night bus routes ("N" prefix) from midnight to 5 AM. Routes N13, N26, and N37 cover popular tourist areas. Fare: ₩2,150 with T-money.
• Taxis: Readily available everywhere. Late-night surcharge (20%) applies midnight–4 AM.
• KakaoTaxi: Usually faster than hailing a taxi on the street at night.
• 24-hour jjimjilbangs: Korean spas accept overnight guests for ₩10,000–15,000 — a popular budget option.

Tip: Save your hotel address in Korean on your phone. Show it to the taxi driver — it's faster and avoids miscommunication.
