How to check a certificate with QR codes
eGov certificates (company registration, real estate and others) carry a chain of QR codes at the bottom. They hold the certificate data and the electronic signature of the state body. Upload the PDF or a photo — every QR code is read, the signed document is reassembled and its signature is checked with KalkanCrypt of the Kazakhstan NCA.
Enbek (ESUTD) employment certificates and printed Doodocs cards are checked the same way. If a QR code only links to the issuer's site, we show the link — open it and compare the data.
FAQ
Why compare the data with the text of the certificate?
Only the data inside the QR codes is signed. The text of the PDF can be changed without touching the codes, so compare the fields shown with what the certificate says.
Not all QR codes were read — what now?
Upload the original PDF from eGov instead of a scan, or take a sharper photo in good light with all codes in the frame.
