Verification infrastructure
Wrap it once. Verify it to the glass.
Everyone wraps the creative. Ours is the only one that can also be read off the screen itself, so a single file reports from inside the ad and is confirmed from outside it.

An example, not a real screen.
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.
The screen was off
The playback log said
✓ Played in full
The glass said
Dark panel. Nobody saw anything.
The frame was frozen

A different advertiser's spot on the glass.
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.
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.
Vojo Passport™ ↗Vojo Harvester™
So we can check it from the outside.
Where a sensor 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.
Vojo Harvester™ ↗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.

Content-level check-in, from inside the creative.
Quality & hold
Freezes, colour faults, duration against the slot.
Harvester · Tier 3
Proof of Display, from the glass.
A dashed ring means the layer was not there — not that it scored badly. The forecourt screen is not being punished for having no Harvester; it is carrying less evidence, and the glass layer is never filled in by inference.
See it happen
All four reports say fine. Watch the score disagree.
The same ad on four screens. Every report comes back saying it played. One screen was off, one froze, one showed it for half the time. The number is the only thing that tells them apart.
The screen is off
Delivery
ClearedThe report still says it played.
Vojo
Nothing on the glass. Score floors.
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.
Method
How strong
Scheduling log
WeakThe spot was booked and dispatched.
Who says so: You do.
Blind to: Cannot see the screen at all.
Player playback log
WeakThe device tried to play the file.
Who says so: Your player does.
Blind to: Reports on itself. A frozen frame still logs as played.
In-creative measurement
SoundThe creative loaded and ran where it was placed.
Who says so: The buyer’s own code does.
Blind to: Rides in the delivery path it is reporting on.
Independent sensor
DefinitiveContent appeared on the glass, matched to the campaign.
Who says so: Something with no stake in the answer.
Blind to: Needs hardware on the screen.
The lower rungs are reliable at their own question — a scheduling log is a fine record of what you booked, and a playback log is good fleet telemetry. They are weak as evidence that an ad appeared for one reason only: the answer to “who says so” is the same party being asked. Read the column and the ladder explains itself.
What it costs
No big contract. Pay for what you check.
The software is free, for your whole team. You pay per ad checked. Sensors cost per screen, only where you want them. Start with one screen and sign nothing.
