In 2025, PromptPay — Thailand's national instant payment system — has become an essential part of daily life for tourists, expats, and locals. Developed by the Bank of Thailand (BOT), the system enables instant, low-cost money transfers between accounts, bill payments, and purchases — without bank delays or high fees.
How does PromptPay work?
PromptPay links bank accounts to personal identifiers — either a phone number or a unique ID (e.g., passport or national ID). Once registered, you can:
- send money to others using their phone number;
- pay bills at stores, cafes, and government offices;
- receive payments from landlords, employers, or partners;
- integrate your wallet with apps like Grab, LINE, and Wongnai.
All transactions are processed in real time, 24/7, including holidays.
Low fees: how much does a transfer cost?
One of PromptPay’s biggest advantages is its minimal fees. As of 2025:
- Up to 5,000 THB — free;
- Up to 30,000 THB — 2 THB per transfer;
- Up to 100,000 THB — 5 THB;
- Over 100,000 THB — just 10 THB.
This is significantly cheaper than traditional bank transfers or international systems like SWIFT. Fees are uniform across all banks.
Who can register?
The system is available not only to Thai citizens but also to foreigners, including:
- expats with work visas and local bank accounts;
- business owners in Thailand;
- tourists with long-term visas (e.g., Elite Visa).
To register, you need:
- an active bank account at a Thai bank;
- a phone number linked to that account;
- proof of identity (passport + visa).
How to register for PromptPay?
Registration has been available since 2017, but in 2025 the process is even simpler:
- Open your bank’s mobile app (e.g., Bangkok Bank, Kasikorn, SCB, Krungsri);
- Find the PromptPay or QR Prompt section;
- Register your phone number or ID;
- Confirm via SMS or OTP;
- Start using the system.
Some banks also allow registration via branch or online chat.
Security and data protection
All transactions are protected by:
- two-factor authentication (SMS/OTP);
- customizable transfer limits;
- fraud detection systems.
If you lose your phone, you can temporarily block your account via the app or bank.
PromptPay for tourists and businesses
The system is widely used by:
- Tourists — for paying taxis, tours, and rentals;
- Expats — for salary receipts and utility payments;
- Businesses — as an alternative to card terminals: just a QR code at checkout.
Many hotels, markets, and transport services now accept PromptPay.
What’s new in 2025?
This year introduced key updates:
- integration with ASEAN Pay — cross-border transfers within Southeast Asia;
- support for foreigners without Thai ID — via passport data;
- higher limits for business accounts.
Conclusion
PromptPay is more than a convenient tool — it’s the digital backbone of Thailand’s financial system. It makes transfers instant, affordable, and accessible to all. If you live, work, or frequently visit the Kingdom, signing up for PromptPay is one of the most practical steps you can take in 2025. One QR code replaces your wallet, card, and printed transfers — making life in Thailand simpler and more modern.
