If there's one thing you absolutely must do the moment you land in Korea, it's get a T-money card. Before you eat, before you find your hotel, before you take a selfie — get the card.
I'm only half joking. Korea's public transport is genuinely world-class, but navigating it without a T-money card is unnecessarily painful. With one? You'll tap your way around Seoul like you've lived there for years.
T-money is Korea's rechargeable transit card — like Opal (Sydney), Oyster (London), or Suica (Tokyo). You tap it on buses, subways, taxis, and even some convenience stores. One card, the whole country.
Where to buy a T-money card
The good news: T-money cards are everywhere in Korea. You don't need to pre-book or plan ahead.
Cost: The card itself costs about ₩2,500–4,000 (roughly $2–3 AUD). This is a deposit — the card is yours to keep or return for a refund at the end of your trip.
How to top up (recharge) your T-money card
Topping up is easy — but here's the catch that trips up most foreigners: foreign credit and debit cards often don't work at top-up machines. Always carry some Korean won in cash as backup.
Load ₩30,000–50,000 to start. That covers about 15–25 subway rides in Seoul, which is plenty for 2–3 days. You can always top up more at any convenience store.

T-money vs single-journey tickets
You might be tempted to just buy single-journey tickets at the subway machine. Here's why T-money is better:
- Cheaper per ride — T-money gives you a small discount on each journey vs single tickets
- Free transfers — Transfer between subway and bus within 30 minutes for free (or discounted)
- No queuing — Just tap and go. No fumbling for coins or tickets
- Works everywhere — Buses, taxis, convenience stores, subways all in one
If you have leftover balance, you can get a refund at subway station service centres or T-money vending machines. Small amounts (under ₩500) may not be refundable. Alternatively, just spend it at a convenience store before you fly home!
T-money outside Seoul
Great news — T-money works across most of Korea, not just Seoul. You can use it in Busan, Daegu, Incheon, Daejeon, and most other major cities. If you're planning a trip outside Seoul (highly recommended!), your T-money card will work just fine on local buses and subways.
You're ready
Buy your T-money card at the airport, load it with ₩30,000–50,000, and you're set. Korea's public transport will take care of the rest — it's genuinely one of the best systems in the world, and with T-money in hand, you'll navigate it effortlessly.
