- ✓Thailand runs on the baht (THB), and despite the malls and contactless readers, much of the country is still cash-and-QR — hotels and malls take cards, but street food, markets, songthaews and small islands generally want cash.

How money actually works in Thailand
Thailand can feel deceptively modern with money. The shopping malls take contactless, the hotels run your card without blinking, and locals pay for almost everything by scanning a QR code on their phones. But step out of the malls and onto a market street, a songthaew, a long-tail boat or a tiny island, and the picture changes: a lot of everyday Thailand still wants cash, or a Thai QR transfer you won't have as a short-term visitor. The practical habit, then, is simple — keep a working float of baht on you and treat the card as a backup rather than the default.
This page is the on-the-ground money guide: how to handle cash, cards and ATMs, how to exchange well, how to keep enough cash for markets and islands, and how tipping really works (more modestly than many visitors expect). It deliberately avoids quoting exchange rates, ATM fees or prices, because those move constantly and a stale number is worse than none — where money meets a specific figure, verify the current rate or fee before you rely on it. For how the money stretches across a whole trip, see the budget page; for paying for rides specifically, see the ride-app page.
Should you use cash or card in Thailand?
Both, but for different things. Cards — including contactless — work comfortably in hotels, shopping centres, larger restaurants, supermarkets and chain stores, so for the 'mall and hotel' half of a trip you can lean on plastic. The other half runs on cash: street-food stalls, fresh and night markets, songthaews and tuk-tuks, long-tail boats, small family guesthouses and tiny island shops generally don't take foreign cards, and the local alternative — a Thai QR-code bank transfer — isn't open to most short-stay visitors who lack a Thai bank account.
So carry a sensible amount of cash for the cash side of the day, and keep small notes: paying a 20-baht snack with a 1,000-baht note is awkward and sometimes impossible for a small vendor. Treat the card as the backup for bigger, formal payments and the cash as the engine of daily spending. Keep the two separate in your head and you'll rarely be caught out — except, as below, on islands and in remote corners where you should plan cash ahead.
How do ATMs and fees work, and how do you avoid wasting money?
ATMs are everywhere in Thai cities and towns, and they're the easiest way to get baht — but they come with a catch that quietly costs travellers money. Thai ATMs typically charge foreign cards a fixed per-withdrawal fee, and that's on top of whatever your home bank adds for a foreign withdrawal. Because the fee is per transaction rather than a percentage, lots of small withdrawals are disproportionately expensive: five small visits to the machine can cost several times what one larger withdrawal would. The fix is to take out a sensible larger amount less often, within what you're comfortable carrying.
A few habits help further. A travel-friendly debit card that refunds or avoids foreign fees can offset the cost if your bank offers one. When a machine offers to charge you in your home currency rather than baht (dynamic currency conversion), decline it and choose baht — the machine's exchange rate is usually worse. And keep your card's daily limits and any travel notifications sorted before you fly, so a withdrawal isn't blocked when you need cash. Fees and limits change, so verify the current charges with your own bank and expect the Thai per-withdrawal fee to apply.
Where should you exchange money, and how much cash should you carry?
If you bring foreign cash to change, where you do it matters. Dedicated currency-exchange counters in tourist areas and cities often give noticeably better rates than airport arrival desks or hotel front desks, so it's usually worth changing only a little on arrival and the rest at a better counter once you're in town. Bring clean, undamaged notes — torn or marked foreign notes are sometimes refused or discounted — and compare the rate offered rather than taking the first window you see. Rates move daily, so verify the current rate before deciding how much to change.
How much cash to carry is about balancing convenience against the islands problem below. In cities, a moderate float plus your card is plenty, topped up from an ATM as needed. The important rule is regional: on smaller islands and in remote areas, ATMs can be few, far apart or temporarily out of cash, and cards may not be accepted, so withdraw or change enough on the mainland before a ferry to cover your island days with a buffer. Arriving on a small island cashless, hunting for the one working machine, is a classic avoidable stress.
How much should you tip in Thailand?
Less than many visitors assume, and never as a rigid obligation. Tipping in Thailand is genuinely appreciated but modest and discretionary — there's no fixed percentage expected the way there is in some countries, and over-tipping out of guilt isn't necessary or expected. The general spirit is to round up or leave small change for good service rather than calculate a precise amount, and to tip a little more for something that was clearly above and beyond.
By setting, a few norms hold loosely. In restaurants, rounding up the bill or leaving small change is normal; note that smarter places may already add a service charge, in which case an extra tip is optional. A small tip for a spa or massage, for a helpful hotel porter or housekeeper, and for a private driver or guide who did a good job is welcome. At street stalls, markets and on songthaews, tipping isn't expected at all. Keep some small notes for this so you can leave a little easily. The overarching point: tip when service is good, keep it modest, and don't feel pressured into a formula — it's a gesture here, not a tax.
