Paying in Thailand: Cash, Cards, PromptPay & QR Payments

Carry at least two payment methods in Thailand. Cash remains the broadest fallback; cards work well at many formal merchants but foreign-card costs depend on the issuer and terminal choice; PromptPay/Thai QR is highly practical for people with access through a participating bank or supported cross-border app. A QR image alone does not mean every foreign wallet can pay it.

Cash

Cash is a reliable fallback for small merchants and situations where a terminal or network is unavailable. Carry manageable amounts and smaller notes, verify change, and avoid exposing a large wallet. Withdrawing cash from a foreign card can include an operator fee, issuer fee and currency-conversion cost; the ATM guide covers those separately.

Cards

Before confirming a card payment:

Check the amount and currency on the terminal.
If a home-currency conversion is offered, compare its disclosed rate/markup with the card issuer's terms; paying in THB leaves conversion to the card network/issuer.
Ask about a surcharge before committing to a purchase and request a receipt.
Keep issuer alerts enabled and report an unrecognized transaction promptly.

The former page's universal 1–3% consumer fee and merchant-processing percentages have been removed. Those costs depend on the card, issuer, merchant agreement and transaction.

PromptPay and Thai QR

The Bank of Thailand describes PromptPay as payment infrastructure for transfers using registered identifiers and standardized QR payments. Access normally comes through a participating Thai bank application. Some cross-border QR linkages allow customers of supported foreign institutions to scan compatible Thai QR codes, but country, institution, currency and limit coverage must be checked in the user's app.

Safe QR process

Open the supported bank or payment app yourself.
Scan the merchant's current QR; do not use an unexpected QR sent by a stranger.
Confirm recipient/merchant name and amount before authorizing.
Show the merchant the completed result without exposing unrelated account information.
Keep the transaction reference until the merchant confirms receipt.

Do not assume PromptPay is universally free. The live bank/app terms and transfer type control any fee and limit; the former “free up to THB 5,000, then THB 10” statement is not retained.

Mobile wallets and contactless payments

An international wallet works only where its underlying card, issuer, device and the merchant terminal are supported. A logo or NFC terminal does not guarantee a specific foreign-issued wallet will work. Keep a physical backup and check the issuer's Thailand and foreign-currency terms before travel.

Choosing by situation

Street market or small local purchase: carry cash; use PromptPay only if your app supports it and the recipient name is correct.
Hotel or major retailer: card is often convenient; verify currency and any deposit or surcharge terms.
Recurring bills: a Thai account's bank app may support bill payment or QR; confirm reference details.
Large purchase: request written payment instructions and receipt; use a traceable method appropriate to the contract rather than splitting payments to avoid checks.
Internet or power outage: keep a reasonable cash fallback.

Common failure points

relying on one foreign card or one phone;
assuming all Thai QR codes accept an overseas wallet;
approving the wrong QR recipient or amount;
selecting a conversion without reading its rate;
using stale screenshots of payment codes;
treating a card authorization as final settlement; and
duplicating payment when a merchant confirmation is delayed.

Costs and timing

Merchant payments are normally immediate from the user's perspective, but authorization, reversal and final settlement times vary. A pending or failed-looking transaction should be checked with both merchant and issuer before paying again. Government charges are not a normal category for everyday merchant payment; bank, card, wallet, FX or merchant charges are commercial costs governed by their current terms.
