Accepting Payments in Thailand for iGaming: PromptPay, Bank Transfer and TrueMoney

Thailand is one of the most mobile-first payment markets in Asia. Almost every adult has a bank app, QR payments are routine in street markets and 7-Eleven stores, and card usage online is modest compared with bank rails. For an iGaming, sportsbook or forex operator serving Thai players, the deposit page is built around three local methods: PromptPay QR, direct bank transfer and the TrueMoney e-wallet. This playbook explains how each behaves for deposits and payouts, what the regulator changed recently, and what to ask a provider before going live.

The legal backdrop in one paragraph

Gambling for Thai citizens remains broadly prohibited under the Gambling Act of 1935. The Entertainment Complex bill, which would allow a few integrated resorts with casino floors, was approved by cabinet in early 2025, shelved after protests in July 2025, suspended when parliament was dissolved in December 2025 and revived in a coalition agreement in May 2026 (The Thaiger). Even in its best case it covers physical resorts, not online play. In practice Thai banks do not knowingly onboard offshore gaming merchants, so collections run through local aggregators and merchant accounts in adjacent categories. Treat that as a risk you manage, not a detail you ignore.

PromptPay: the default rail

PromptPay is the national real-time transfer scheme operated by National ITMX under Bank of Thailand oversight, linking a bank account to a phone number, national ID or merchant QR code. Juspay, citing Mastercard and ITMX data, reports more than 81 million registrations by March 2025 and about 2.16 billion transactions worth 4.2 trillion baht in September 2025 alone. Transfers up to 5,000 baht are free and larger ones cost a few baht, so players never think about fees.

For a deposit the operator shows a dynamic QR code with the amount embedded. The player scans it from any Thai bank app, confirms, and funds land in the receiving account within seconds. The reference inside the QR lets the PSP match the payment to the player automatically, which is why QR has replaced manual bank-transfer matching for most operators.

Two cautions. A merchant QR is only as stable as the receiving account behind it; if that account is frozen, every QR pointed at it dies at once. And the limits a player sees are set by their own bank app, and many retail users keep daily caps well below what a VIP wants to deposit.

Direct bank transfer: still needed for size

Classic bank transfer means the player copies an account number from the deposit page and sends money through mobile banking. It is slower to reconcile because the player may type a wrong amount or omit a reference, but it offers higher ceilings for established customers and a familiar fallback when QR is paused. Good PSPs match incoming transfers against expected amounts and timestamps and push a real-time feed so the balance updates within a minute.

The important change is regulatory. In August 2025 the Bank of Thailand announced a 50,000 baht daily transfer limit as an anti-scam measure, then clarified that it targets specific groups: customers flagged as fraud risks, customers with limited history at that bank, and customers whose normal transfers never exceed 50,000 baht. Regular high-value users keep limits matched to their behaviour (The Star, reporting the BOT statement of 20 August 2025). Separately, banks and police have frozen large numbers of suspected mule accounts during 2025, and legitimate merchants caught in the sweep have reported slow releases (Pattaya Mail). For an operator this means deposits from new or low-activity accounts will hit daily caps more often, and any receiving account that looks like a mule account, meaning many small inbound transfers followed by rapid outbound sweeps, is a freeze candidate.

TrueMoney Wallet: the e-wallet layer

TrueMoney, part of the Ascend Money group, is Thailand's largest standalone e-wallet, with Tazapay citing more than 17 million active users. It can be topped up with cash at 7-Eleven, which matters for players who prefer to keep gambling deposits away from their main bank account, and the bank statement shows a wallet top-up rather than a transfer to an unfamiliar account. The trade-off is limits: wallet balances and daily spending are capped by the user's KYC tier, far below what a bank transfer allows. TrueMoney is a solid second option for small and medium deposits and a cash on-ramp; it is not the rail for a 200,000 baht VIP.

Side by side for deposits

Payouts and settlement

Withdrawals are almost always paid back to the player's bank account through PromptPay or standard transfer, because that is where the money came from and where the name can be checked. Banks now screen outbound transfers against reported fraud lists, so payouts to flagged accounts will fail and should be rerouted only after a manual review. Ask your PSP how payouts are funded: from the collection float on a T+0 or T+1 window, or from a prefunded balance. Settlement of your margin to an offshore entity is a separate conversation that always involves currency conversion and a corridor fee.

Questions to ask a Thai payment provider

How many receiving accounts sit behind the QR pool, and how fast is rotation after a freeze? What is the real first-deposit success rate for new versus returning players? Are bank transfers matched automatically or do players upload a slip? Is TrueMoney offered directly or through another aggregator? Who absorbs the loss when an account is frozen? A provider who answers in writing is worth more than one who quotes the lowest rate.

FAQ

Is PromptPay enough on its own for a Thai deposit page? It covers most players and deposit sizes, but you still want bank transfer for large deposits and TrueMoney for wallet or cash users. Three methods also give you a fallback when one channel is paused.

Does the 50,000 baht daily limit apply to every Thai player? No. The Bank of Thailand has said it applies to customers flagged as high risk, customers with little history at their bank and customers whose normal transfers stay below that figure. Established customers keep their usual limits.

Can players deposit with international cards? Some do, but card acceptance for gaming in Thailand is thin, authorisation rates are poor and chargebacks are expensive. Local rails are faster, cheaper and more predictable.
