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.

Solutions

The same verification, applied to the job your screens do.

  • Media ownersSell every slot on evidence: stop giving plays away, hold your rate card, and answer a queried spot with a lookup.
  • Agencies and brandsCheck a campaign across every network it runs on, with one wrap and one comparable score per play, not a different log from each seller.
  • Programmatic platformsFor SSPs, DSPs and exchanges: an independent score on every play, and you decide what clears.
  • Compliance messagingHospitals, pharmacies, transport hubs, venues, councils and workplaces: show a notice was displayed, not just sent.

For buyers who already verify

Already verifying? Now prove it.

Your verification tells you each play happened. Vojo Passport™ works alongside it and tells you which plays to trust, right down to the glass. Keep your partner. Try it on your next campaign.

Same campaign, two reports

Six plays. Six yeses. Now you know which to trust.

On the left, what your verification already tells you. On the right, the same plays with Passport added: a score for each one, and the reason behind it.

The morning

Your partner: 6 of 6 played.

With Passport: 3 to accept, 2 to hold, 1 to question.

Illustration using sample sites and scores from a demo network. Not a real campaign.

Every yes on the left is true: the player did run the ad. The right column is what you didn't have before: how far to trust each play, against a bar you set yourself.

What it takes

Wrap it once. Keep everything else.

  1. 01

    Send us the creative

    The one you already run, including the HTML creative from your verification partner. It goes through Passport once.

  2. 02

    Traffic it as before

    Same screens, same buy. Your partner's tag rides inside the wrap and keeps reporting to them.

  3. 03

    Read both reports

    Theirs tells you each play happened. Ours scores how far to trust it, up to the glass on Harvester-equipped screens.

Passport

The wrap around it

Reports from inside every play and grades it, so the yes arrives with how far to trust it.

Your verification

Your current partner

Their creative and tag run unchanged inside the wrap. Their report still tells you it played.

Played: yes

+ Ran in full+ Right screen, right time+ vTrust Score

Harvester · on the glass

The screen itself

Where a sensor is fitted, it reads what actually appeared on the panel and matches it to the play.

Nothing to lose

Don't switch. Stack.

Nothing gets removed or replaced. Vojo is the layer that tells you how much to trust what you're already getting.

  • Your partner

    Stays. Same contract, same reports.

  • Your workflow

    Same creative, same screens, same buy.

  • Your screens

    Same networks, same media owners. Nothing to install.

Questions

Straight answers. Before you try it.

No. Your partner's creative runs inside Passport as it is, and its tag still reports to them. Nothing is removed from it. We check your partner's tag inside the wrap at the start of a pilot, before any of your campaign runs.

Pilot

Run Passport on your next campaign.

Keep your partner, add Passport, and put the two reports side by side. Tell us when the campaign runs and we'll plan around it.
