Check the payment code before paying it.

A QR code on an invoice can pay someone the invoice never names. Barcoder reads the code, reads the document, and says whether the two agree — for people and for their AI agents.

Mismatch

The code pays a different account than the invoice names. Do not pay from this QR.

Example case · synthetic data · the EPC QR is real and scans

Drop an invoice here, or choose a filePDF, PNG or JPG, up to 5 MB. A photo of a paper invoice works. Reading an invoice uses one case.

The file is read and then dropped: Barcoder keeps the details it found as text, never the document.

Trial cases on this device, no account needed.

Payee details from each case are recorded as text, for verifying account owners. Documents are never stored. Privacy wording is pending.

#how-it-works

One case, four steps.

Extract and validate together make one case: one document, read end to end, however many calls it takes. Reading a clean code and generating one stay free.

Read
Finds every code on the page and names its standard.
QR, PDF417, Data Matrix and the 1D families, matched against 470 documented standards.
Free
Extract
Pulls the payee, IBAN, amount and reference out of the document itself.
Invoice photos, scans, PDFs and screenshots. Every extracted field is shown for confirmation.
In a case
Validate
Checks the code against the document, and both against the rules.
IBAN and reference checksums, EMVCo CRC, VAT numbers through VIES, scam-URL lookups, payee and amount consistency.
In a case
Generate
Writes a correct, scannable payment code from confirmed fields.
HUB3, EPC QR, Swiss QR-bill, UPN, Pix, UPI and 35 more payload formats.
