Cards, ATMs and cash in Thailand: what to expect

Thailand is a cash economy with a card layer on top. In Bangkok, Chiang Mai, Phuket and Pattaya, hotels, shopping malls, chain restaurants, convenience stores, hospitals and tour agencies take Visa and Mastercard without fuss. Step into a market, a family-run guesthouse, a songthaew, a minivan or a small island shop and the answer is usually cash only. Plan on both, and never let your cash run to zero on a remote island where the single ATM may be empty or offline.

ATMs are everywhere in cities and towns, and almost all accept foreign cards. The machine will offer a withdrawal in baht; the exchange rate applied is the network rate, which is normally fair. The cost is the flat Thai bank fee added to every foreign-card withdrawal, plus whatever your own bank charges for an overseas cash advance. Because the Thai fee is per transaction, not per baht, one ฿10,000 withdrawal is much cheaper than five ฿2,000 ones.

At card terminals you will often be asked whether to pay in baht or in your home currency. Choose baht. Paying in your own currency is dynamic currency conversion: the terminal's bank sets the rate and adds a margin, and it is almost always worse than letting your card network convert. The same rule applies to online bookings made from a Thai hotel's payment page.

Cards also work for booking transport and hotels in advance, which is worth doing for sleeper trains, domestic flights and popular island rooms in high season. For day-to-day spending, keep a working cash float and top it up at a bank ATM rather than a standalone machine in a tourist strip, which can carry the same fee with worse reliability.

The numbers below are 2026 estimates for a foreign card. Your own bank's fees sit on top and vary widely, so check your card's overseas terms before you fly.

Withdraw larger amounts less often to blunt the flat Thai fee. A ฿10,000 withdrawal costs the same ฿220 as a ฿2,000 one, so the effective cost drops sharply with size.

Carry two cards from different networks, stored separately from each other and from your phone. If one is blocked for suspected fraud, the other keeps the trip moving. Tell your bank you are travelling if it still requires that.

Keep a small emergency stash of USD or EUR notes, plus a few thousand baht, in a different bag from your wallet. Major exchange booths in cities handle clean, unmarked foreign notes.

Photograph your card fronts and the emergency phone numbers, and store the images in cloud storage rather than only on the phone you might lose. Report a lost card to your bank immediately; Thai police reports are usually needed only for insurance claims.

Use bank-branded ATMs inside branches or malls where possible, and cover the keypad. Skimming happens in tourist areas, and standalone machines in quiet spots are the usual targets.

If you plan to stay a while, a Thai bank account is possible on some long-stay visas but paperwork-heavy; most visitors simply budget the ATM fee into their daily costs.
