Cash Culture & ATMs
Why cash still rules, ATM fees, and where cards actually work
Thailand is simultaneously more cash-driven and more digitally advanced than most visitors expect. Cards are the awkward middle option.
Where cards work, and where they do not
Cards are fine at hotels, malls, supermarkets, chain restaurants and most places aimed at visitors. Cards are useless at markets, street food, songthaews, small local restaurants, massage shops and most of the places you will actually remember.
Carry cash. Not a lot — a couple of thousand baht covers a normal day — but carry it, and keep small notes. Breaking a 1,000 baht note at a food stall is genuinely awkward.
The ATM fee everyone pays once without noticing
Every Thai ATM charges a flat fee on foreign cards, regardless of how much you withdraw, and your own bank may add more on top. Withdrawing small amounts repeatedly is an expensive habit. Take out more, less often, and keep it somewhere sensible.
Always decline the conversion
When an ATM or a card machine offers to charge you in your home currency instead of baht, say no. That option — dynamic currency conversion — uses a poor rate and costs you a few percent every time. Choose baht and let your own bank do the conversion.
QR payment
Thailand's QR system is excellent and used everywhere, including by market stalls. It runs off a Thai bank account, so it is mostly relevant if you live here — see Banking for Foreigners. If you have it, you will barely touch cash again.
Practical habits
- Break big notes at supermarkets and 7-Eleven, where nobody minds.
- Keep a small amount separate from the rest for daily spending.
- Count change without making a performance of it. Mistakes happen; they are rarely deliberate.
- Tell your bank you are travelling or expect a block at the worst moment.
- Bank branches and exchange booths beat airport counters on rate, usually by a lot.
None of this is complicated. It is simply a place where having a few hundred baht in your pocket opens doors that a card does not.
