Make Your Certificates Checkable
A printed certificate is only as good as the ability to check it. Most employers never do, because checking means finding the issuer, finding the right person there, and waiting for a reply. So forged qualifications survive.
A QR code makes the check take five seconds: scan, land on the issuer's verification page, see whether the certificate is real and still valid. What follows is how to do that properly, including the part that is easy to get wrong.

Why It Works
Checks that actually happen
A five-second scan gets done. An email to a training department does not.
Expiry is visible
Safety and compliance certificates lapse. The page can show current status, which the paper never can.
Revocable
A withdrawn certificate can be marked as such centrally, even though the printed copy still exists.
Worth more to your graduates
A qualification that an employer can verify instantly is more useful than one that requires trust.
How to Set It Up
- 1
Host a verification page per certificate on your own domain, with a unique, non-guessable identifier in the URL.
- 2
Show the essentials: holder name, qualification, issue date, expiry or status, and issuing body.
- 3
Generate a code per certificate above, or in bulk from a CSV for a whole cohort.
- 4
Print it on the certificate with a line of text explaining what it is for — "Scan to verify this certificate at ourdomain.example".
Frequently Asked Questions
Does the QR code make the certificate impossible to forge?
No. A forger can copy the code along with everything else, and the copy scans the same. What stops the forgery is that the code leads to your domain, and your record is the authority. Someone forging the whole thing would have to forge your website too.
Should the certificate details be inside the code itself?
No — that is the common mistake. Data encoded in the code is fixed at printing, cannot be revoked, and can be copied into a fake code by anyone. Put an identifier in the code and the truth on your server.
How do I keep the verification URLs private?
Use long random identifiers rather than sequential numbers, so nobody can enumerate every certificate you ever issued. Show only what a verifier needs, and never the holder's personal contact details.
