Verification infrastructure for digital out-of-home, modular by design.

  • Platform overviewHow the parts fit together: wrap the creative, read the glass, grade the play.
  • PassportFor everyone. Wrap creative once, verification rides inside. Harvester-compatible by default on fitted screens.
  • HarvesterPatentedOn-glass sensor that produces Proof of Display, independent of the player log.
  • vTrust ScoreOne comparable score from all the proof on a play. Glass proof counts only where a Harvester is fitted, never invented.
  • IntegrationsAPI, webhooks and MCP, pipe verified plays into the exchanges and tools you already use.

5 of 6 would still go in your report as delivered.

  • The screen was off or black Missed
  • A frozen frame held the whole slot Missed
  • No signal, or the wrong input on the panel Missed
  • Something was blocking the panel Missed
  • The wrong content was showing Missed
  • The content stopped before it finished Caught

Based on what each method can and can’t see, explained in the methods compared.

Why the answer is so often no

The log reports from inside. The failure is outside.

The CMS knows what it told the player to do, and the player knows what it tried to do. Neither can see the panel, so a frozen frame or a loose cable looks just like a successful play.

What to do with your result

Whoever you are, you can close the gap.

There's nothing to replace. Here's where you start.

If you sell screens

Every miss is something you can't show a buyer, and buyers price risk into a rate whether or not you do.

Your first step

Wrap the creative with Passport and add a Harvester at the sites where proof changes the price. Your CMS and players stay as they are.

See how it works for you

If you buy screens

Every miss is something you're taking the network's word for.

Your first step

Wrap your own creative with Passport. The network has nothing to install, and you get one comparable score per play across every network.

See how it works for you

If you clear trades

Every miss is a play you'd clear on the network's own report, not on evidence.

Your first step

Take an independent vTrust Score on every play over API and webhooks, and set your own bar for what clears.

See how it works for you

If a notice has to be seen

A schedule shows a notice was sent, not that it was on the screen. Every miss is a question you couldn't answer if someone asked.

Your first step

Wrap the notice with Passport and add a Harvester on the screens where a missing notice would matter most. Your signage system stays as it is.

See how it works for you

What closes the gap

Ride inside the content. Watch the glass.

Two layers of evidence, graded into one score on every play.

Vojo Passport™

Wraps the content once, with nothing for the network to install, so a buyer can use it directly. It reports from inside, so it knows what ran and whether it finished.

How it works

Vojo Harvester™

A sensor watching the screen, independent of the player log. It sees what nothing inside the system can: black, frozen or blocked. Always ships with Passport.

How it works

vTrust Score™

One comparable score on every play, from the evidence present. It never invents glass credit.

How it works
