The crucial difference

A card alone is not enough. Its current version must also be verifiable.

When scanned, ZertCheck displays the current version of the card stored by your organization. The photo, name, role, design and validity can be compared directly with the card presented.

Scan the QR code

The standard smartphone camera opens the verification page directly in the browser.

See the current status

Valid, expired or revoked: the status is immediately visible.

Compare the card presented

Verification shows the official, currently stored version of the card – not just a technical result.

The verification behind it

ZertCheck makes cards verifiable at any time.

Every ZertCheck Card is directly linked to our live verification. Anyone who scans the QR code immediately sees the version of the card currently stored by your organization and its current status.

ZertCheck does more

ZertCheck also verifies other documents.

Courses & continuing education

Attendance confirmations, course certificates and exam records that can still be verified online years later.

Mandatory & safety training

Occupational safety, internal training, recurring training and certificates with limited validity.

Existing cards

Existing membership, employee or role cards can be supplemented with a ZertCheck QR code – printed directly or added as a sticker.

No app required

A standard browser and smartphone camera are all you need for verification.

Automatable

REST API for single or bulk issuance directly from your system.

Independent verification link

Verification works regardless of how the original document was shared.

Frequently asked questions

Do we need to replace our existing software?

Do recipients need an app or an account?

No. The verification link opens directly in the browser. A QR code can also be opened using the standard smartphone camera.

Can a record expire or be revoked?

What data does ZertCheck store?
