# The public verification page

Scanning the QR code of a [material resource](/material-resources/) opens a read-only page that can be viewed **without a 4HSE account**. You get the QR code from the [Verification QR](/material-resources/generate-the-qr) button or from the [printed badge](/material-resources/print-the-badge).

## Compliance status

[Section titled “Compliance status”](#compliance-status)

The compliance status of the resource is derived from the statuses of its actions:

Compliance status

Condition

**Valid**

**Expiring soon**

at least one action is expiring, none is expired or missing

**Not valid**

at least one action is expired or missing

A resource with no associated actions is **Valid**.

## Certificates

[Section titled “Certificates”](#certificates)

For each action the page shows only the most recent certificate, the one the action’s status is based on. For equipment the section is titled _Certificates (including calibrations)_, for substances _Certificates (e.g. safety data sheets)_.

Each certificate shows its name, action type, issue date, expiry (with the time, if the certificate uses hourly precision), its attachments and one of _Draft_, _Valid_, _Expired_, _Revoked_ and _Rejected_.
