Do I need a special certificate scanner app?

No. On most modern phones the built-in camera scans QR codes directly. Point it at the certificate's QR code and tap the link. Any free QR scanner app also works, or you can type the certificate's short code into the issuer's verify page.

How do I download a certificate from a QR code?

Scan the QR code with your phone camera to open the verification page, then use the Download or Save option there to get the official copy. Keep the verification link too — a live link is more trustworthy to employers than a saved file.

What should happen when I scan a certificate QR code?

It should open a verification page on the issuer's own website that clearly states whether the certificate is authentic and unaltered, and shows who issued it. If it opens raw text or an unrelated site, treat the certificate with caution.

Is scanning a certificate the same as verifying it?

Not quite. Scanning opens the link; verification is what the page then does — checking the certificate against a signed record to confirm it is genuine. A good QR does both in one step.

Certificate Scanner: Scan & Download from a QR

People search for a "certificate scanner" expecting to need special software. Good news: you don't. If a certificate was issued properly, the QR code is the scanner interface and your phone's normal camera is the scanner. This guide covers how to scan a certificate QR code, what a genuine result looks like, and how to download the certificate from its QR code.

How to scan a certificate QR code

Open your phone's camera (or any QR-scanning app). On modern iPhones and Android phones, the built-in camera reads QR codes with no extra app.
Point it at the QR code on the certificate — usually in a corner. Hold steady until a link notification appears.
Tap the link. It should open a verification page on the issuer's website, not a random domain and not a blob of raw text.
Read the result. A trustworthy page states clearly whether the certificate is authentic and unaltered, and shows who issued it.

If your camera doesn't scan QR codes automatically, any free QR scanner app works, or you can type the certificate's short code into the issuer's verify page by hand.

How to download a certificate from a QR code

If you are the recipient and want to save your own certificate, the QR code is often the fastest route:

Scan the QR with your phone camera.
On the verification page, look for a Download or Save PDF option — a well-built page offers the official copy right there.
Save it to your device, or share the verification link directly (a live link is more trustworthy to employers than a forwarded file).

Note: downloading the certificate and verifying it are different actions. The download gives you the document; verification proves it is genuine. Always keep the verification link, not just the PDF — the link stays checkable, a saved file does not.

What a genuine scan result looks like

It opens a page on the issuer's own domain.
It says more than just "valid" — it names the issuer and confirms the data hasn't changed.
Altering a single character in the certificate would make it fail, because the check is based on a cryptographic signature over the data.

Red flags when scanning

The QR opens plain text (a name and date) instead of a verification page — that proves nothing.
The page is on an unrelated domain with no issuer detail.
There is no QR or code at all — just a PDF with no way to check it.

Scan, verify and download with QRCertificates

Certificates issued through QRCertificates are built for exactly this. Every certificate carries a QR code and a short code that open a branded, login-free verification page. Anyone can scan to confirm authenticity, the recipient can download the official copy, and the record is Ed25519-signed so a tampered version is rejected. No certificate scanner app, no account — just a phone camera. Verification is always free.
