A rechargeable transit card makes repeated subway and bus rides in Korea more convenient. Sales locations and accepted top-up methods can vary, so check the instructions where you buy or recharge it.

Buy and top up

Check airports, convenience stores, and subway stations for card sales. The card price and stored value may be separate, and payment methods vary.

Tap in and tap out

Tap once when entering and again when leaving. Use one card per traveler and listen for the confirmation sound.

Low balance or card errors

If a gate stays closed, check the balance and try the card alone rather than inside a wallet. Ask a station information center for help.

After the trip

Refund rules and fees depend on the card and location. Check current conditions if you want a refund or plan to keep the card for another visit.
