Your browser reads the text you paste, or the text layer of the PDF you drop, and draws the QR code. Nothing is uploaded: apart from loading the page itself, this site makes no network requests, and there is no server that sees your invoice.
Nothing is stored and nothing is tracked: no history, no cookies, no analytics. Your browser remembers only the language you chose.
Fien finds the IBAN, the amount, the reference and the beneficiary with fixed rules, not with a model. Every value she fills in is a piece of your text, highlighted so you can compare it with the source. Where she had to choose between several, the field says so.
“Check digits OK” means the IBAN or the structured reference is well-formed: its check digits add up. It does not prove that the account belongs to the beneficiary. Compare the details with the original, and once more on your banking app’s confirmation screen.
The QR code follows the European EPC standard that banking apps read. It carries these four details and nothing else.
Tante Fien is made with love and looked after by Sofuto.
