Manufacturing eligibility verification

Manufacturing sites mix employees, contractors, and visitors across OT systems. AffixIO returns signed allow or deny at plant gates and line boundaries without growing another PII silo.

Manufacturing eligibility verification proves a person may enter a zone or perform a task under policy, without exporting HR records to every reader.

The challenge

Visitor and contractor sprawl

Temporary workers and multi-vendor contractors create stale credentials and incomplete audit trails.

Stale badges

Offboarded contractors retain physical or QR access.

OT vendor copies

Each system stores a fragment of workforce data.

Shift predicates

Time-bound clearance is hard across disconnected readers.

Use cases

Manufacturing scenarios

Use for zone entry and task eligibility.

Zone turnstiles

Spent-proof QR for high-throughput entry.

turnstile

Line certification

Prove training predicates without document upload.

ZK

Visitor escorts

Short TTL guest credentials.

How verification works

  1. 01

    Issue

    Policy authority defines a Noir circuit for the rule set. Witness inputs come from systems that already own the records.

  2. 02

    Bind

    Proof is bound to event context: programme ID, expiry, geography, and anti-replay nonce. ML-DSA-65 signature applied at issue.

  3. 03

    Present

    User, agent, or device presents the credential via API call or secure QR at the service boundary.

  4. 04

    Verify

    Verifier receives allow or deny plus Merkle reference. No personal data retained at the verifier by default.

FAQ

Frequently asked questions

Does this work air-gapped?

Offline verification patterns are available; deployment depends on your edge design.

How do we pilot?

Start with sandbox mint/verify, then a single plant gate.

Get started

Validate manufacturing eligibility verification on the live sandbox, then scope a pilot with engineering.
