A certificate QR code is a scannable link. In VerifyInt, that link opens a record associated with a unique certificate ID. The useful part is the current issuer record behind the link: the QR graphic by itself is not a security guarantee.
From a printed certificate to a current record
Once an approved institution publishes an eligible certificate, VerifyInt creates its unique reference and QR link. The institution can place them in its saved certificate template, so each generated PDF carries the reference for the correct recipient. People checking the PDF or printout can open the record without creating an account.
The reference stays associated with that record. If the issuer revokes the certificate, the verification result changes to reflect its status; an old PDF does not silently become evidence of a currently active certificate. Read how dates and revocation affect a record.
Check the destination before opening it
Preview the address shown by your phone. For a VerifyInt-hosted record, check that the hostname is verifyint.com, rather than a similar-looking spelling. Public certificate lookup does not require card details or a VerifyInt password. If a page unexpectedly asks for either, close it and start from the issuer’s independently verified website.
The UK National Cyber Security Centre notes that criminals also use QR codes in phishing. Its guidance on spotting scams explains why the destination deserves the same care as any other link.
Make QR codes usable on paper
- Keep the QR dark on a light, uncluttered background.
- Leave clear space around it and avoid stretching the graphic.
- Print the certificate ID as readable text beside it.
- Check the exported PDF and an actual printed copy on more than one phone.
There is no single print size that guarantees a scan on every device. Test the final artwork, paper and print process you will use. A readable reference provides a fallback when a camera cannot focus.
If scanning is unavailable
You can enter the certificate ID in the verification form. VerifyInt also offers camera scanning with browser permission and QR image upload. These options open the same record; none replaces checking the issuer and document details.
