02 / THE INCUMBENTS

Why they can't follow

There are three ways a site checks people at the door today, and each one carries a cost that is baked into how it was built.

Cloud video analytics ships footage of workers to a server. It inherits the biometric exposure, the storage bill, the breach risk and the subpoena. That is the product. You cannot turn it off without turning the product off.

Badge systems verify a card. They know who walked in. They have no idea whether that person was equipped to be there.

Manual audits are sampled, self-reported and unprovable. The clipboard is filled in at the start of the shift and stops being filled in by the second one.

WorkCheck's engine sits outside all three: on-device reference-set matching, a tamper-evident record, and zero stored imagery of people. A video vendor cannot get here by improving. They would have to stop storing video, and video review is their business.

03 / THE ENGINE

What actually runs

Advanced computer vision software integrated with discrete silicon. Inference runs on a dedicated vision processor at the sensor, isolated from the host, with depth and active infrared alongside color. A small vision model finds the objects. A reference matcher checks the garment against the kit the site set up from three photos. The verdict is written as a hash chained to the one before it. Then the image is gone.

RECORDabout 60 bytes, hashed and chainedtime, gate, kit, verdict. image discarded

The same code runs on the gate box, on a phone, and in the cloud, and all three give identical answers on the same input. That is what lets the free phone app and the gate share kits, and what lets a customer start on a phone and move to a door without rebuilding anything.

Where it goes

Check-against-a-reference applies anywhere dress is regulated and a dispute is expensive. The reference changes. The engine does not.

Food safety and cleanroomsHairnet, smock, gown, booties. Garment compliance where a camera that stores video is not welcome.

Pharma and labsGowning checks at the airlock, logged per entry, for the auditor who will ask.

Franchise brand complianceIs the crew in uniform at 400 locations this morning? One kit, pushed everywhere, checked locally.

Events and venuesStagehands, front of house, security, by zone and by shift, for the night it matters.

PPE training stationsA station that watches the drill and confirms the sequence, without a trainer standing over it.

Defense and governmentFlight line, depot, base construction gates. Compliance without identity. More

The long arc is risk. Every checkpoint produces the enforcement record that insurers and counsel currently wish existed. That turns compliance from a cost nobody can prove into data an underwriter can price. WorkCheck at the industrial gate is the wedge. Verified physical compliance is the company.
