BANGKOK, THAILAND – Expats living in Thailand are increasingly navigating a cashless society, with the PromptPay system revolutionizing daily transactions.
For many long-term residents from Germany, Austria, or Switzerland, the seamless and rapid QR code payments common in Thailand present a question: how can they participate in this system, and what specific changes should they expect by 2026?
This guide aims to explain how PromptPay functions for expatriates, highlight solutions available without a Thai bank account, and detail the implications of a new Wise license from the Bank of Thailand, effective from May 2026. For those equipped with the right tools, a life without cash is achievable, even as a foreigner.
What is PromptPay and why does it affect everyone
PromptPay is the state-sponsored real-time payment system operated by the Bank of Thailand. Launched in 2016, it links bank accounts to a mobile or identification number. When making a payment, users scan the merchant’s QR code, confirm the amount, and the transfer is immediately reflected in the recipient’s account, eliminating the need for PIN entry at terminals or card fees.
The system boasts over 90 million registered users and is accepted at more than nine million locations, from large bakeries to street food stalls. In 2024 alone, PromptPay facilitated billions of transactions. For residents in Thailand not part of this system, everyday purchases often require cash, or they may be unable to pay at all.
Thai bank account: Requirement and obligation for pensioners
Individuals with a Thai bank account can directly activate PromptPay through their bank’s mobile application, such as Bangkok Bank, Kasikorn, SCB, or Krungthai. This process takes mere minutes: navigate to the ‘Payments’ section, select PromptPay, link a mobile number as the identifier, and confirm the terms. Subsequently, any QR code in the country becomes a valid payment option.
For pensioners holding a Non-O or Non-OA visa, a Thai bank account is not merely an option, but a necessity. Those who extend their residency permits based on financial proof must demonstrate 800,000 Baht, which can only be done through a local bank account. PromptPay activation in this scenario is a complimentary added benefit that most banks offer immediately.
Which banks are still open for foreigners
Since 2025, Thailand’s major banks have significantly tightened their account opening rules for foreigners. Holders of Non-O, Non-OA, or LTR visas can typically still open accounts with Bangkok Bank and Kasikorn, provided all documentation is complete. This includes passports, visa stickers, residency permits, TM30 receipts, and, in some branches, proof of address from a landlord.
Digital Nomad Visa (DTV) holders face challenges, as this visa is considered a non-immigrant visa without a permanent residence under immigration law, leading many branches to reject applications. Those who wish to proceed should inquire directly at Bangkok Bank branches in major cities, as rules can vary by branch and officer, with no guarantee of acceptance.
Wise under Bank of Thailand license: What applies from May 2026
The most significant development for expats without a Thai bank account in 2026 is that Wise began operating under its own license from the Bank of Thailand on May 19, 2026, and is now fully integrated into the PromptPay system. Wise account holders can directly scan Thai merchant QR codes, from market stalls to restaurants, with funds converted to Baht and transferred in real-time.
Limitations of this new solution include a maximum of 10,000 Baht per transaction and 30,000 Baht daily. Those who previously used Wise for ATM withdrawals in Thailand will need to adjust their approach, as cash withdrawals from ATMs for Thai-registered Wise accounts will cease from September 2026. Existing cards linked to a Thailand address will be deactivated and replaced with new ones that do not support this service.
TAGTHAi Easy Pay: The official tourist solution
For individuals visiting Thailand for a few weeks or months without a local bank account, the TAGTHAi Easy Pay system offers the most convenient option. Launched in March 2025 by the Tourism Authority of Thailand in collaboration with Kasikorn Bank, it is specifically designed for international visitors. Setup takes less than 15 minutes and requires no proof of residency.
The process involves presenting a passport at a KBank exchange counter—available at Suvarnabhumi and Don Mueang airports, as well as over a hundred branches and major shopping centers—exchanging foreign currency for Baht, and applying for the PAY&TOUR prepaid card, which is free. Subsequently, download the TAGTHAi app, link the card, and scan PromptPay QR codes just like a local. Up to 10,000 Baht daily can also be withdrawn from KBank ATMs. Top-ups are exclusively available at KBank FX counters; bank transfers or foreign credit cards are not accepted.
TrueMoney Wallet: Usable, but with restrictions
TrueMoney is Thailand’s most widely used e-wallet outside the traditional banking system, run by the CP Group, which also operates 7-Eleven stores nationwide. Foreigners can register using their passport, with approval taking up to three business days. The maximum wallet balance is 50,000 Baht.
A key restriction is that those without a Thai bank account can only top up the wallet in cash at a 7-Eleven counter; foreign credit cards are not accepted. For those using TrueMoney’s WeCard for international purchases or streaming services, a 3.5% foreign currency fee applies, making it viable only for Baht transactions within Thailand. Nevertheless, TrueMoney remains a practical and widely used option for PromptPay QR payments in daily life.
ASEAN agreement: Who can pay directly with their home bank
Travelers from Singapore, Malaysia, Indonesia, Vietnam, Cambodia, Laos, China, and Hong Kong can scan Thai QR codes directly using their home banking app. This is facilitated by the ASEAN Payment Connectivity agreement, which links PromptPay with payment systems in neighboring countries. Supported services include PayNow from Singapore, Touch ’n Go and BigPay from Malaysia, and Alipay and WeChat Pay from China.
No such agreement exists for visitors from Germany, Austria, and Switzerland, as their European banking systems are not connected to PromptPay. The Bank of Thailand is exploring partnerships with additional countries, but there is no specific timeline for Europe. Until then, Wise, TAGTHAi, or a local bank account remain the only reliable methods.
Security and practical tips
PromptPay utilizes PIN confirmation or biometric authentication for every transaction. Funds are held on bank servers, not directly on the device. In case of phone loss, the account remains secure, but the SIM card should be immediately blocked, as TrueMoney and other wallets are tied to the mobile number.
A common scam involves fake QR code stickers placed over legitimate merchant codes. After scanning, the app displays the recipient’s name, which must match the merchant. If uncertain, confirm with the merchant before proceeding. Public Wi-Fi is not recommended for financial transactions; a local SIM with a data plan provides a more secure connection.
ATM fees and what digital payments save
Every cash withdrawal from a Thai ATM currently incurs a foreign transaction fee of 220 to 250 Baht, in addition to home bank charges. For those needing small amounts daily, withdrawal fees alone can quickly add up to thousands of Baht per month. PromptPay transactions between Thai bank accounts are free; payments via Wise or TAGTHAi incur moderate currency exchange fees.
Another cost trap is Dynamic Currency Conversion. When prompted at an ATM or terminal to pay in your home currency (e.g., Euros), the local bank determines the exchange rate, which is often significantly worse than the interbank rate. As a general rule: always opt to pay and withdraw in Thai Baht, never in your home currency.
