What is PromptPay QR Code Generator?
A PromptPay QR Code Generator creates the scannable barcode that Thai banking apps use to send money to your linked citizen ID, mobile number, or e-wallet. Instead of reading out a 13-digit number, you show one QR and get paid instantly. This tool builds the official EMVCo payload — including the CRC-16 checksum — entirely offline in your browser.
Key Benefits
- Get paid with one scan — no account numbers to share
- Optional fixed amounts prevent wrong payments
- Works offline; your ID never leaves your device
- High-res PNG for stickers, invoices, and shop displays
Common Use Cases
- •Market stalls and street food carts accepting cashless payments
- •Freelancers adding a payment QR to invoices
- •Schools, temples, and charities collecting donations
- •Splitting bills by generating a QR with an exact amount per person
- •Shop owners printing a table QR so customers pay without queuing
How to Use the PromptPay QR Code Generator
- Choose your ID type: Select whether your PromptPay is linked to a 13-digit citizen ID, a mobile number, or a 15-digit e-wallet ID.
- Enter your PromptPay ID: Type the digits of your citizen ID or phone number. The input keeps numbers only and validates the length as you type.
- Set an amount (optional): Leave the amount blank for an open payment, or enter a fixed THB amount such as 150.50 so payers cannot change it.
- Scan or download: Let customers scan the preview QR with any Thai banking app, or download the 1024px PNG to print for your shop or invoice.

Frequently Asked Questions
Which ID can I use to receive PromptPay payments?
Any Thai bank account linked to PromptPay works: a 13-digit citizen ID, a 10-digit mobile number starting with 0, or a 15-digit e-wallet ID. The tool encodes each type correctly per the EMVCo spec.
Does the QR work with all Thai banking apps?
Yes. The payload follows the official PromptPay EMVCo merchant-presented QR format with the mandatory CRC-16/CCITT checksum, so every major Thai banking app can scan and pay it.
Is it safe to put my citizen ID into this tool?
Yes. The entire payload is built locally in your browser with JavaScript — no network request is made and nothing is uploaded. You can even disconnect from the internet and it still works.
What happens if I leave the amount blank?
A QR with no amount tag is an open payment: the payer types the amount in their banking app before confirming. Entering an amount embeds it in the QR so it cannot be changed.
Can I print the QR for my shop?
Yes. The download button saves a 1024×1024 PNG, which is sharp enough for stickers, table tents, invoices, and posters. QR codes remain scannable when printed in black on white.
