How verification works
Certificates are designed to be checked, not just displayed.
Every certificate has a public page at academy.safeguard.sh/cert/<id> — no account needed to view it
The page shows live status: valid, expired, or revoked — never a stale PDF
A QR code on the printed certificate points at the same page
One-click add to your LinkedIn profile; shared links unfurl as rich cards
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
