Retail eligibility verification

Retail needs fast age and access decisions without building a new ID image archive at every till. AffixIO returns signed allow or deny with privacy-preserving predicates.

Retail eligibility verification confirms age or access predicates at the point of sale or store boundary as a signed outcome.

The challenge

ID image hoarding at scale

Each retailer and POS vendor that stores ID images multiplies breach impact.

Document copies

Age checks create standing archives of identity images.

Staff badge sprawl

Back-of-house access lists drift.

Franchise variance

Inconsistent controls across locations.

Use cases

Retail scenarios

Apply at customer and staff boundaries.

Age-restricted goods

Over-18 predicates at till.

age

Self-checkout gates

Signed allow without staff ID handling.

SCO

Stockroom access

Staff clearance with spent-proof.

Proof pipeline

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

Is this Online Safety related?

Age predicates align with OSA-style gates for platforms; retail uses the same proof pattern at POS.
