Thailand Currency & Money Guide

The official currency of Thailand is the Thai Baht (code: THB, symbol: ฿). Banknotes are issued in denominations of 20 ฿ (green), 50 ฿ (blue), 100 ฿ (red), 500 ฿ (purple), and 1,000 ฿ (grey/brown). Coins circulate in 1, 2, 5, and 10 baht values, along with smaller 25 and 50 satang coins (100 satang = 1 baht).

Payment habits in Thailand combine modern digital commerce with a resilient cash economy. While major hotels, shopping malls, supermarket chains, and upscale restaurants widely accept credit cards, cash remains indispensable for street food vendors, local night markets, taxis, songthaews, temple donations, and small island businesses.

Experienced travellers avoid relying solely on a single payment method. Carrying a mix of a small amount of cash in Thai baht, two separate debit/credit cards, and an emergency reserve of clean foreign banknotes provides the most reliable financial flexibility.

Cash is universally accepted across Thailand. In bustling local markets and roadside fruit stalls, cash is often the only accepted method for foreign visitors.

When withdrawing money from ATMs, machines dispense predominantly 1,000 THB banknotes. While 1,000 THB notes are accepted without issue in department stores, supermarkets, and larger restaurants, small vendors, street food stalls, and taxi drivers may struggle to provide change for a 1,000 THB note on a 40 THB purchase.

A practical strategy is to break larger 1,000 THB notes at convenient locations such as 7-Eleven, BTS/MRT ticket counters, or supermarket checkouts by buying a drink or snack. This ensures your wallet always carries a healthy supply of 20, 50, and 100 baht notes for daily incidental spending.

ATMs (known locally as cash machines) are widely available across Thailand, found outside convenience stores, bank branches, transit stations, and shopping centres.

Virtually all Thai ATMs charge a local operator fee on withdrawals made with foreign debit and credit cards. In addition to this Thai ATM fee, your own domestic bank or card issuer may charge an international transaction fee or foreign cash withdrawal fee.

Because the Thai ATM operator fee is generally charged per transaction rather than as a percentage, making fewer, larger withdrawals can reduce the total fixed fees incurred over your trip. However, travellers should balance larger withdrawals against personal security and avoid carrying more physical cash than they feel comfortable handling.

Always inspect the ATM screen carefully before confirming your transaction, and make sure to take your cash and card promptly before stepping away from the machine.

When withdrawing cash from a Thai ATM or paying with a foreign card at a retail terminal, the machine may ask whether you wish to be billed in Thai Baht (THB) or converted directly into your home currency (e.g. USD, EUR, GBP). This service is known as Dynamic Currency Conversion (DCC).

If an ATM or payment terminal offers conversion into your home currency, check the displayed exchange rate and any additional conversion fees before accepting it.

Choosing to be billed in Thai Baht (THB) usually leaves the currency conversion to your own card issuer or card network (such as Visa or Mastercard), which often uses standard wholesale market exchange rates.

Visa and Mastercard are the most widely accepted international card networks in Thailand. American Express, JCB, and UnionPay are accepted at select luxury hotels, department stores, and international chain establishments, but have narrower acceptance elsewhere.

Contactless card payments (tapping physical cards or smartphones with Apple Pay / Google Pay) are common at major retail chains, coffee shops, and modern transit systems (such as the Bangkok MRT subway). However, many smaller independent shops and tour agencies still require chip-and-PIN insertion or only accept cash.

Some smaller merchants that accept cards may apply a surcharge (typically 2% to 3%) or enforce a minimum purchase amount (such as 300 THB). Always check with the staff before assuming card payment is accepted without additional fees.

To avoid automated fraud blocks while travelling abroad, inform your bank of your travel dates if your institution requires notice, and ensure you have access to two-factor authentication (2FA) for online card transactions.

Currency exchange booths are plentiful throughout international airports, major tourist districts, shopping malls, and transport hubs. Legitimate exchange counters clearly display buy and sell rates on electronic boards.

Exchange counters located inside airport arrival zones before immigration frequently offer less favourable rates compared to downtown city booths or dedicated exchange kiosks located on the airport train link concourse level.

Thai money exchangers enforce strict standards on banknote physical condition. Banknotes that are torn, heavily creased, marked with ink, or worn may be rejected or offered lower exchange rates. For currencies like USD, higher-denomination banknotes ($50 and $100) often receive slightly better exchange rates than smaller bills ($1, $5, $10, $20).

Thai law requires money exchange providers to verify customer identity. Always carry your physical passport when planning to exchange cash at a currency counter.

PromptPay is Thailand's national instant interbank payment infrastructure. In everyday life, Thai residents pay almost everywhere—from high-end restaurants to roadside fruit carts—by scanning PromptPay QR codes with their local Thai banking mobile applications.

Seeing a PromptPay QR stand on a merchant counter does not automatically mean any foreign visitor can scan and pay it with a standard overseas banking app. PromptPay is primarily integrated with Thai domestic bank accounts.

Certain cross-border QR payment agreements exist between Thailand and specific regional banking networks in Southeast Asia (such as Singapore's PayNow, Malaysia's DuitNow, Indonesia's QRIS, and Cambodia's Bakong). Visitors holding qualifying accounts in these partner countries can scan Thai PromptPay QR codes directly through their home banking apps.

For general international travellers from Europe, North America, Oceania, and elsewhere, standard domestic PromptPay scanning is generally unavailable unless using a supported visitor e-wallet or international payment partner. Do not rely exclusively on QR payments as your sole funding source.

Alipay and WeChat Pay are widely supported across Thailand in major retail stores, convenience chains (like 7-Eleven), pharmacies, duty-free outlets, and tourist-oriented businesses, primarily serving Chinese travellers and supported international wallet accounts.

Through the Alipay+ cross-border payment network, select international mobile wallets (including Touch 'n Go eWallet from Malaysia, GCash from the Philippines, Kakao Pay from South Korea, and TrueMoney) are increasingly accepted at participating Thai merchant terminals.

Merchant acceptance of specific e-wallets varies considerably by location and merchant terminal hardware. Travellers should look for the specific wallet logo displayed at the checkout counter rather than assuming universal acceptance across Thailand.
