What is a VietQR bank transfer code?

It is the EMVCo QR that Vietnamese banking apps read: the bank's BIN, the account number, an optional amount and an optional message. The page builds the same fields a bank app expects and adds the CRC at the end.

Will my banking app read it?

Scan it once with your own banking app before printing or sending it. The page shows in plain words what the code will send, so you can check the bank, account, amount and message first.

Are Vietnamese letters allowed in the message?

Banks want plain Latin letters, so the page removes the marks: “Trả tiền ăn trưa” becomes “Tra tien an trua”. The message is cut at 50 letters.

Can I choose the colours?

No. The code is black on white, which is the safest for a scanner and for a printed page.

Is anything uploaded?

No. The QR is made in your browser, and the bank list is a file on this site. Your account number, password and message are not sent anywhere.
