Upload a picture of a payment QR code or paste the text inside it. You get the IBAN, amount, symbols and note, and you can open the payment in the generator to change it or switch the format.
Your browser reads the code. The image and the payment never leave your device.
Checking an invoice before you pay. The reader shows the full IBAN and amount from a QR code on an invoice or in an email, and flags an IBAN with a wrong checksum.
Converting between formats. Slovak invoices carry PAY by square, which most banks outside Slovakia do not read. Open the payment in the generator, switch to EPC QR and download a code any SEPA banking app accepts.
