Evidence-Based Verification
See how PlugZ reduces counterfeit risk with physical evidence, human review, advisory AI signals, NFC records when available, escrow, and PlugZ Chain provenance.
What the review is built on
The process is evidence-first, not promise-first.
Physical evidence
Photos, item details, packaging, condition, serial or NFC signals, and shipment context are kept as review material.
Human verifier review
Approved verifiers inspect the item and issue the operational review outcome. AI does not replace that step.
Advisory AI signals
Visual AI can flag risk signals and evidence gaps. It returns probability and supporting observations, not a final verdict.
NFC and chain records
When available, NFC evidence and PlugZ Chain records support provenance and make the review history easier to inspect.
How the verification path works
A buyer should be able to follow the evidence trail from listing to receipt.
Seller evidence
The listing starts with item photos and details that establish the first evidence set.
Hub routing
After a sale, the item moves through PlugZ-controlled logistics toward an approved verifier.
Verifier inspection
The verifier reviews physical signals, item condition, listing match, and any advisory risk signals.
Recorded outcome
The review output is tied to the evidence trail and, where available, NFC or PlugZ Chain records.
Buyer receipt
The buyer receives the reviewed item with tracking and can inspect the available evidence record.
What AI can and cannot say
Allowed
AI may provide advisory probability, evidence notes, risk signals, and regions of concern for verifier focus.
Not allowed
AI must not say an item is authentic, verified, original, rejected, or fake as a categorical final claim.
Final buyer-facing authenticity language must come from a human verifier or from NFC cryptographic evidence when that evidence is available. This is a product and legal boundary, not a styling preference.
What to inspect
Evidence photos
Compare listing photos, verifier photos, condition notes, and packaging details.
Verifier context
Look for the reviewed-by identity, review timing, and any notes attached to the item.
NFC status
When the item has an NFC record, use it as a cryptographic reference point for the physical object.
Provenance record
Review the available PlugZ Chain or history record for custody and verification events.
