QR Payment and IBAN Calculator

Two practical financial literacy tools: create a QR code that can be scanned in any Czech banking app, or convert a Czech account number to an international IBAN and back. All calculations run only in your browser – nothing is sent anywhere.

Enter the account number and amount – the QR code is created automatically.

What is a QR payment?

QR Platba is the Czech standard (SPAYD format) supported by virtually all Czech banks. Instead of typing the account number and symbols, simply scan the code in your mobile banking app – no typos, and the payment is done in seconds.

What is IBAN?

IBAN (International Bank Account Number) is the international format of an account number. A Czech IBAN always has 24 characters:

  • CZ – country code
  • 2 check digits – protect against typos
  • 4 digits – bank code
  • 6 + 10 digits – prefix and account number padded with zeros

Tips for safe payments

  • Always check the recipient's name and the amount in your banking app before sending.
  • Never scan QR codes from unverified e-mails or text messages without checking them.
  • A valid Czech account number must pass the modulo 11 check – the calculator verifies it for you.

The tools work offline and do not store or send any data. The list of bank codes is based on the Czech National Bank (ČNB) code list; the current version is available on the ČNB website.
