Before you leave

Prepare your payment methods.

  • Check overseas purchase and withdrawal access, PIN requirements, limits and fees with each card issuer.
  • Keep a physical main card and a separately stored backup; make sure you can receive issuer approval messages.
  • Decide which transit product suits your route and how you will fund it.

Pay with confidence

Your plan, in order.

Adjust the cash allocation for your party, transit product and planned purchases.

  1. 1 · Plan
    01

    Split the remaining budget

    Subtract prepaid accommodation and tickets. Write down the remaining spending budget, planned card spending and expected cash needs. A cash withdrawal is not a second expense.

  2. 2 · Prepare
    02

    Set your starter cash

    Use ₩100,000 solo, ₩150,000 for a couple or ₩200,000 for the example family as adjustable first-day-or-two allocations, not required minimums. Add cash-only plans and transit-card purchase costs; reduce top-ups if you have a suitable pass.

  3. 3 · Arrive
    03

    Exchange or withdraw won

    Use an authorized exchange service or a Global ATM displaying your network. Check the final amount, operator fee, issuer charges and withdrawal limit. Keep the receipt.

  4. 4 · Travel
    04

    Fund the correct transit product

    Have cash for a standard physical T-money top-up. For a short-term Climate Card or single-journey ticket, check whether the new station machine supports your foreign card and what fee it displays. Do not assume the bank card itself opens the gate.

  5. 5 · Pay
    05

    Ask, check the currency, confirm

    Ask whether your foreign card works before committing to a purchase. Use KRW unless you have intentionally compared a conversion offer. Confirm that the transaction succeeded.

  6. 6 · Recover
    06

    Handle a decline calmly

    Check acceptance, try the physical card if appropriate, review any issuer alert and try your backup. Agree a cash or other supported payment with staff. For bookings, check confirmation before paying again.

  7. 7 · Review
    07

    Check tonight, top up tomorrow

    Record wallet cash and each transit balance. Replenish against the next day’s plans. Before leaving Korea, check refund rules for the specific product and avoid unnecessary last-minute loads.

Make it your trip

Useful changes.

  • Market-heavy day: allocate more small notes to purchases after checking acceptance.
  • Hotel-and-shopping trip: most planned spending may stay on cards, while the cash reserve stays modest.
  • Family trip: track each transit balance separately and arrange the child fare category before use.
