Put a QR code on the certificate design
Add a recipient-specific QR code to the certificate so a printed or downloaded copy leads back to its public verification page.
A PDF in a group chat can be forwarded, renamed, or edited. A printed certificate on a wall has no clickable link at all. The QR code is the bridge between the physical certificate and the record behind it.
Each certificate design can include a recipient-specific QR code.
Adding it
Open the certificate design, add the QR element, and place it where it will survive printing. The code is generated per recipient at issue time, so it points at that recipient's public page rather than a generic workspace URL.
Leave enough quiet space around the code, keep it large enough for a phone camera, and check the contrast against the background. A QR code placed over a dark photograph is technically present and practically unreadable.
What it is for
A printed award can be checked at a desk or on a wall. A downloaded certificate can be scanned from a phone without typing a credential ID. A conference badge or a poster can carry the same route back to the record.
What it is not
The QR code is a convenient route to verification, not the proof itself. A code that points somewhere else does not become a valid certificate; the public page still checks the signed credential and the issuer record.
The QR code is optional. A certificate without one can still be reached from its link or certificate ID.
