2. Where can I pay? (Purchase and Top-up Stations)

4. Frequently Asked Questions (FAQ)

Q. Can I top up a 30-day (regular) pass with an international card?
Currently, this has been applied first to short-term passes (Day Passes), which are in high demand among foreign tourists. The inclusion of 30-day passes is under future review.

Q. Are there any separate fees?
Yes, a service fee of approximately 3.7% is included in the payment amount when using an internationally issued card. Considering the hassle of using cash and currency exchange fees, it is considered a reasonable level.

Q. What if the card is not being read properly?
If the IC chip payment doesn't work, try Samsung Pay/Apple Pay (linked to an international card) or KakaoPay QR payment. If the issue persists, ask for help at the Information Counter.
