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.

Start here

Someone said the ad played. Nobody looked.

Every check in use today ends up asking the same machine that showed the ad. It keeps its own diary, the diary says yes, and nothing in the chain ever looks at the screen.

In every one of these the log does not go quiet. It reports a successful play. That is the difference between evidence that is incomplete and evidence that is wrong, and it is only visible to something watching the screen rather than the software.

How it works

One wrapped file. Every level it can reach.

The creative goes through our wrap once. It does everything any wrap does, and one thing none of them can: it can be recognised from outside the ad, by something looking at the screen.

  1. 01

    Vojo Passport™

    A wrap that can be seen from outside.

    Creative goes through Passport once. From inside the ad it reports back on any network, with nothing to fit, the way a wrap should. It also carries something a sensor can pick out on the glass and match to this exact play, which no other wrap does.

    On its own it still only sees as far as the ad.

    ✓In the ad: delivered in full

    Vojo Passport™↗
  2. 02

    Vojo Harvester™

    So we can check it from the outside.

    Harvester always ships with Passport, because the signal it looks for is the one Passport put there. Where one is fitted, it finds that signal in the light coming off the panel and confirms this play ran, independently of the ad and the player. Patented in the UK and the US.

    Only on screens where a sensor is fitted. You choose which ones are worth it.

    ✓On the glass: seen and matched

    Vojo Harvester™↗
  3. 03

    vTrust Score™

    They work as one.

    You do not pick a level or wire anything up twice. The file simply goes deeper where it can, and everything it found becomes a single number for that play.

    On a screen with no sensor you still get a number, and it tells you that is what happened.

Already have a verification partner?

Already verifying? Now prove it.

Most HTML-based verification tells you an ad played. Vojo Passport™ wraps your existing verification creative and adds the quality and proof behind that yes. On Vojo Harvester™-equipped screens, that extends to on-glass proof of what actually displayed.

  • No switching

    Your current partner keeps reporting as normal.

  • More data

    A quality score behind every play.

  • On-glass proof

    Confirmed display on Harvester-equipped screens.

All four reports say fine. Watch the score disagree.

The same ad on four screens. Every report comes back saying it played. One has no sensor, so nothing can confirm it. On the other two the glass flatly contradicts the report, and that is a different thing from simply not knowing.

Cleared

The report is all there is.

Vojo

Passport says it ran and nothing contradicts that. With no sensor on the glass it stays unproven rather than wrong, so it scores what is actually there and stops short of MAX.

What that gets you

Charge more. Or pay less.

Both sides see the same number, so there is nothing left to argue about.

  • If you sell screens

    Price what you can prove.

    Screens you can prove are worth more than screens you can only describe. And you stop giving away free ads to cover a number you cannot back up.

  • If you buy them

    Pay for what showed.

    Blank screens. The wrong ad. Half an ad. You can see them now, so you stop paying for them.

  • If you clear the trade

    Settle on something solid.

    Pick a pass mark and settle against it, instead of haggling over who to believe.
