Accepting Payments in Thailand: PromptPay, TrueMoney and Beyond
Key Takeaways
- PromptPay — Thailand's national instant-payment system — is the default way Thai customers pay online and offline.
- TrueMoney extends reach to wallet-first users; bank transfer remains the trusted fallback.
- QR-first checkout with pre-filled amounts performs best for Thai mobile traffic.
Thailand moved to real-time payments earlier and more completely than most economies. PromptPay, launched under the Bank of Thailand's national e-payment programme, connects bank accounts to mobile numbers and national IDs — and its QR standard is accepted everywhere from street stalls to e-commerce checkouts. For online merchants, understanding the Thai stack is straightforward; executing it well is what separates good acceptance from great.
PromptPay: the centre of gravity
For online payments, PromptPay QR is the flow to optimize. The customer scans a code in their banking app, the amount and reference arrive pre-filled, and confirmation is real time. Two execution details matter:
- Dynamic QR over static. Generate a unique QR per transaction with the exact amount and a unique reference — it eliminates typing errors and makes automatic matching trivial.
- Expiry handling. Thai customers often pause mid-payment. QR codes need sensible lifetimes and a clean regeneration flow when they expire.
Where TrueMoney fits
TrueMoney is Thailand's leading e-wallet, popular with younger and unbanked segments and deeply integrated into the broader ecosystem of convenience-store top-ups. For merchants whose audience skews mobile-first or includes customers without active mobile banking, offering TrueMoney alongside PromptPay captures sessions that would otherwise fail.
Bank transfer: still the trust anchor
Direct bank transfer remains widely used, particularly for higher-value transactions where customers prefer the familiarity of their banking app's transfer flow. The operational keys are the same as elsewhere in the region: unique references, automatic matching, and awareness of each bank's maintenance windows.
Putting it together
The high-performing Thai checkout leads with PromptPay QR on mobile, offers TrueMoney for wallet users, and keeps bank transfer available as the fallback — all behind one integration with unified settlement in THB. That's exactly how Help2Pay delivers Thailand within our regional coverage.

Frequently asked questions
Do Thai customers really expect QR at online checkout?
Yes — PromptPay QR has become the default mental model for paying in Thailand, online included. A Thai checkout without a QR option feels foreign to local customers.
Can foreign merchants accept PromptPay?
Through a local payment partner, yes. Help2Pay handles the local rails, collection and THB settlement so merchants don't need their own Thai banking setup.
How fast do PromptPay payments confirm?
Transfers are real time; with dynamic QR and automatic matching, the order is typically confirmed within seconds of the customer approving in their bank app.
