Proof of Display

Not proof of play. Proof of display.

Most DOOH platforms bill you when a media player says it played your ad. Admitt bills you only when independent hardware confirms your ad actually appeared on screen. Here's exactly how that works.

  • Included free on every campaign
  • Unverified displays never billed
  • Every listed screen is verified
The Difference

A play log is a promise. A display is a fact.

The industry standard, proof of play, is the player reporting on itself. Proof of Display is independent confirmation that your ad was actually on the glass.

Proof of play — the industry standard

The media player reports on itself — the same device that plays the ad writes the log
A 'played' log can't tell if the screen was off, damaged, or showing something else
Verification is often a paid add-on, reconciled after your money is spent
Disputes come down to your word against a log file

Proof of Display — the Admitt standard

A separate verification device observes the screen — independent of the player
Playback claims are checked against what actually appeared on the display
Verification is built into every campaign at no extra cost
Billing is built on confirmation: unverified displays are never charged
How It Works

From booked slot to confirmed display

Four steps, fully automated, on every single play — not a sampled audit after the fact.

01

Your ad plays

The screen's media player renders your creative in its booked slot, exactly as scheduled.

02

Independent capture

A dedicated verification device at the venue — physically separate from the player — observes the display and records what actually appeared, along with screen-health signals.

03

Match & confirm

Our verification engine matches the independent observation against the booked play. Only when the two agree is the display confirmed.

04

Billed on confirmation

You're charged for confirmed displays only. Anything unconfirmed — an offline screen, a playback failure — is automatically returned to your budget as credit.

Who Builds It

Built by Vojo

Proof of Display hardware and verification technology are built by Vojo, Admitt's sister company — and we're upfront about that. What makes verification trustworthy isn't who builds the device. It's that the device confirming your ad is never the device playing it, that verification is a listing requirement for every screen on the marketplace, and that our billing only ever runs on what it confirms.

Want to see it in practice? Every screen on our live map has active verification hardware.

What verification changes

Proof of Display isn't a reporting feature. It's the foundation the whole commercial model stands on.

You never pay for a display that didn't happen

Billing runs on confirmed displays, not playback promises. Unverified spend comes straight back as credit — automatically, without a dispute process.

For advertisers

Screen health, watched continuously

The same independent observation that confirms your ads also flags failing or degraded screens, so problems surface fast instead of at month end.

For advertisers

Verified inventory earns more

Screens that prove delivery are screens advertisers rebook. Verification turns venue inventory into inventory buyers can trust with real budgets.

For venues

Trust without the audit trail fight

Venues and advertisers see the same confirmed numbers. No reconciliation spreadsheets, no he-said-she-said — one verified record of what ran.

For both sides
