The short answer

Visitors: use a South African card with no conversion fee — Capitec, with GoTyme as a backup — wherever cards are taken: hotels, malls, restaurants, Grab, the MRT. Carry cash from occasional larger ATM withdrawals for stalls, markets and taxis, and add a tourist QR option such as the TAGTHAi Easy Pay card if you want to scan QR codes. SnapScan, Zapper and South African banking apps can't pay Thai QR codes. Residents: a Thai bank account with PromptPay does almost everything for free; keep a South African card for bookings and a little cash for the rest. Always pay in baht, never rand.

A two-week holiday, costed three ways

To show how much the choice of payment method matters, take a South African couple on a two-week trip who spend ฿40,000 (about R19,608) in Thailand: ฿25,000 on cards at hotels, malls and restaurants and ฿15,000 in cash for markets, street food and taxis.

• Careful: Capitec card for the ฿25,000 (R0 extra) and three ATM withdrawals of ฿5,000 for the cash (3 × R177.84 = R533.52). Total extra cost: about R534.
• Typical: a card with a 2.75% foreign fee for the ฿25,000 (about R337) and the same three withdrawals at a similar ATM cost (about R534). Total: about R871.
• Costly: the 2.75% card again (R337), cash taken ฿1,000 at a time (15 × R177.84 = R2,667.60), and one hotel bill of ฿10,000 paid in rand through dynamic currency conversion at a 5% mark-up (about R245). Total: about R3,250.

Same holiday, same spending — a difference of more than R2,700 from three habits: the card you use, how often you visit an ATM and whether you say "baht" when the machine asks. The DCC figure is an illustration; real mark-ups vary by machine.

Visitor or resident: two payment kits

Our guides to fee-free cards for spending in Thailand and opening a Thai bank account explain each part of the kit.

PromptPay and Thai QR in a nutshell

PromptPay is Thailand's national instant payment system. Shops display a Thai QR code; customers scan it in a Thai bank app or e-wallet, check the name and amount, and confirm — the money moves instantly, usually free for both sides. South African banking apps, SnapScan and Zapper can't scan Thai QR codes, and South Africa isn't among the countries with cross-border QR links to Thailand, so visitors need a tourist option such as the TAGTHAi Easy Pay card or a verified TrueMoney Wallet. Residents with a Thai bank account — or a Thai-registered Wise account — can pay directly.

For the details of each tourist option, see our guide to Thai QR payments for foreign visitors.

Paying for transport

• BTS Skytrain: cash, QR at the machines, single-journey tickets or a rechargeable Rabbit card — no contactless bank cards yet.
• MRT, Yellow and Pink lines, Airport Rail Link: tap in and out with a contactless Visa or Mastercard.
• Grab and Bolt: add your South African card in the app before you land, and switch on international use in your banking app.
• Metered taxis and tuk-tuks: cash, in small notes.
• Trains, buses, flights and ferries: book online by card where possible; cash at small piers and bus stations.

Our guide to paying for tours and domestic transport has the full detail.

Paying safely

Always pay in baht. If a card machine or ATM offers to charge you in rand, decline — dynamic currency conversion costs far more. Never share a one-time PIN, and keep your South African number active and protected against SIM swaps. Before you confirm any QR payment, check the name that comes up, because fake QR stickers placed over real ones are used to divert payments. Use ATMs inside banks or shopping malls and cover the keypad, and keep your card in sight when you pay in restaurants and hotels. It's worth carrying two cards from different banks, kept apart, so one problem doesn't leave you stuck. And never scan a QR code to “receive” money — that's always a scam.

Our guide to payment scams covers the warning signs.

Paying for big things

Keeping your payment tools topped up from South Africa

Every method in this reference needs money behind it. Visitors simply spend from their rand account, but anyone staying for months needs a plan for moving rand into baht without losing a slice each time. The right route depends on how much you move and how often.

Small, regular amounts: spend on the card

For a holiday or the first weeks of a move, the cheapest option is usually to leave the money in South Africa and spend on a card with no conversion fee. Capitec converts at Visa's rate with nothing added at the till, so a ฿1,000 dinner costs about R490 with no extra charge. The cost that adds up is cash: each Capitec withdrawal costs R70 plus the Thai ATM's ฿220, about R178 in all. Taking ฿20,000 at a time keeps that under 2%; taking ฿1,000 at a time pushes it past 36%.

Monthly living money: a flat-fee transfer

Once you have a Thai account, a single monthly transfer into it is usually cheaper than living on a South African card. Capitec charges a flat R175 to send an international payment, so on R30,000 the bank's fee is well under 1% — although the exchange rate it applies matters more than the fee. The Thai bank usually deducts 0.25% on receipt, with a minimum of ฿200 to ฿500. Paying in once a month and then using PromptPay for everything in Thailand is how most long-stay South Africans keep costs down.

Deposits, school fees and property: a specialist

For larger sums — a rental deposit, a school term, a car or a condo — the exchange rate decides the cost. A one-percentage-point difference in the rate on R500,000 is R5,000. This is where an FX specialist earns its place: rates closer to the market, fixed-rate tools and someone who checks the Thai account details before the money moves.

If children are part of the move, plan the fees early. Ask about school-fee planning, or compare schools in our international schools directory.

Allowances and paperwork

South African residents can send up to R2 million a calendar year under the single discretionary allowance, and up to a further R10 million with SARS approval for the foreign investment allowance. Every international payment needs a balance-of-payments declaration, which your bank completes with you. Non-residents and people who have ceased tax residence need SARS PINs for their transfers instead. None of this touches card spending in Thailand, but it matters when you pay for property.

Holding foreign currency offshore

Some South Africans in Thailand prefer to keep savings in US dollars or euros outside South Africa, then convert to baht as they need it. Our number-one choice for that is a Standard Bank Offshore account in the Isle of Man or Jersey, which we can help you open.

Inside South Africa, a foreign currency account such as FNB Global, the Absa Currency Investment Account or Nedbank's Foreign Currency Account can hold dollars or euros in your own name, ready to send to Thailand when the rate suits.

When a payment doesn't work

• South African card declined: international use may be switched off, or your bank may have blocked it for security. Check the card's settings and approve the payment in your banking app, then try again — or use your backup card.
• Online Thai site won't take your card: some Thai websites only accept Thai cards. Try a different card network, PromptPay, or pay at the counter.
• QR payment shows "failed" but money left: don't pay twice. Show the seller your app history; failed payments are normally reversed by the bank.
• Charged in rand when you asked for baht: ask the merchant to refund and recharge in baht, and dispute it with your card provider if they won't.
• ATM kept your card: freeze it in your app, call your bank's international line (Capitec: +27 21 941 1377), then contact the ATM's bank with your passport.

Small change and tipping

Large ATM notes (฿1,000) can be hard to use at small stalls and in taxis, so break them in 7-Eleven, supermarkets or restaurants and keep ฿20, ฿50 and ฿100 notes for small payments. Tipping isn't expected in most places, but rounding up a taxi fare or leaving small change in a restaurant is appreciated; some upmarket restaurants add a service charge to the bill.
