QR payments in Thailand: where to source baht
PromptPay is the backbone of cashless payments in Thailand. Most supermarkets, cafes and services accept QR. For a foreigner without a Thai bank account the most direct route to QR payments is via cash baht or a TrueMoney Wallet, both funded through USDT.
How PromptPay works
PromptPay is linked to a Thai phone number or national ID. The seller shows a QR code, the buyer scans it through any Thai bank app and money transfers instantly. For a non-resident without a Thai account PromptPay is not directly accessible, but there are working alternatives.
TrueMoney Wallet: the best option for tourists
TrueMoney Wallet is a fintech wallet foreigners can open with a passport. Accepted at 7-Eleven (over 14,000 locations across Thailand), Lotus's, Big C, thousands of restaurants and online services. Balance limit is 50,000 THB, daily payment limit 30,000 THB.
- Download the TrueMoney Wallet app
- Verification: passport + selfie
- Top-up: at any 7-Eleven cashier with cash baht
- In full: USDT → cash baht (via us) → TrueMoney Wallet → QR payments
Thai bank account as a tourist: realistic?
Kasikorn (KBank) opens accounts for tourists at some branches with a passport, hotel booking and return flight confirmation. An account gives access to the KPlus app and full PromptPay. It takes 1–2 hours but is not guaranteed — it depends on the specific branch.
Where cash is the only option in Thailand
- Street food stalls and markets (Chatuchak, Floating Market): cash only
- Tuk-tuks and motorbike taxis: cash
- Small family shops outside tourist areas: cash
- Monasteries and temples for donations: cash
Practical tip
The optimal strategy for most tourists and nomads: exchange 20,000–50,000 THB in cash through us, use it for daily expenses and TrueMoney top-ups. For large payments (rent, online airline tickets) — a Wise card or virtual wallet.
