Reference

Receipts arrive as PDFs, screenshots or photos. Constaia extracts amount, date, payer, beneficiary, IBAN and description, validates the IBAN and checks it matches what you expected.

A receipt does not prove the money arrived: always reconcile with your bank statement.
The edited_suspected and screen_photo_suspected warnings are signals, not proof.

What it checks

IBAN. ISO 13616 check digits and length per country.
Expected values. Amount, reference or IBAN match the ones you provide.
Holder. Name, number or date of birth match what you expect.

FAQ

Does Constaia prove the document is authentic?

No. It checks the type, data consistency and your rules, and flags signals such as a possible edit or a screen photo. That does not prove authenticity.

Is a copy of the document kept?

No, unless you ask for it. With storage "none" (the default) the file is deleted when the analysis ends.
