Credit Cards in Asia: What Works and What Doesn’t

Not all cards are equal for Asia travel

Using the wrong credit card in Asia costs real money — foreign transaction fees of 2–3% on every purchase, plus unfavorable dynamic currency conversion schemes at many Asian terminals. Using the right card eliminates these costs entirely.

What to look for in a travel card

Zero foreign transaction fees. Visa or Mastercard (more widely accepted than Amex in most of Asia). No cash advance fees if you need to use it at ATMs. Ideally: ATM fee reimbursement, travel insurance included, chip and PIN (not just chip and signature).

Dynamic Currency Conversion: always decline

When a terminal asks “would you like to pay in USD/GBP/EUR?” — always choose local currency. Dynamic currency conversion lets the merchant set the exchange rate, always at 3–8% worse than your bank’s rate. Always select local currency. Always.

Where cards work well

Japan (at most stores, konbini, hotels — less at small restaurants), Singapore (almost everywhere), South Korea (broadly accepted), Thailand (tourist-facing businesses), Bali (hotels, larger restaurants, some shops). Cards work less reliably in rural Vietnam, Cambodia, Laos, and local markets throughout the region.

The cash backup

Even in Singapore and Japan, carrying equivalent of $50–100 in local cash is appropriate for markets, small restaurants, temple entrance fees, and tips. Card acceptance is high but never universal. — book via Tiqets for the best deal.
