SECURE PROVENANCE LAYER · ISO-grade tamper evidence

Scan it.
Verify it.
Trust it.

Hologuard mints a tamper-evident authenticity seal for every physical unit you make — a serialized holographic label backed by an on-chain provenance record. One scan tells the truth: genuine, or a clone.

01 How a scan works

From shop shelf to cryptographic proof in under 400 milliseconds.

Tap or scan the seal

A buyer taps the NFC chip or scans the QR on the Hologuard label with any phone camera — no app install required.

Challenge the chip

The chip signs a fresh random nonce with its embedded key. A replayed photo of a QR can't forge a live signature — so screenshots fail.

Resolve provenance

We resolve the serial against its on-chain record: who made it, which lot, every custody hop, and whether the seal was ever marked VOID.

VALID or VOID

The buyer sees a plain verdict and the full provenance trail. Tamper or duplicate-scan anomalies flip the verdict to VOID and alert the brand.

02 Why clones don't pass

Three independent layers a counterfeiter would have to defeat at once.

PHYSICAL

Tamper-evident void pattern

Peel the label and a latent VOID mesh delaminates into the adhesive. The seal can be read once, on the genuine unit, in its original place.

OPTICAL

Guilloche + holographic ink

A machine-generated guilloche micro-border and a diffractive holo foil that ordinary print and scan-reprint pipelines can't reproduce.

CRYPTO

Live-challenge signatures

Each chip holds a unique key it never exports. Verification is a fresh challenge–response, so a copied serial number alone is worthless.

04 SDK & NFC integration

Issue seals from your line; verify from anywhere. Two calls.

// 1. Mint a seal for a unit coming off the line
import { Hologuard } from "@hologuard/sdk";

const hg = new Hologuard({ apiKey: process.env.HG_KEY });

const seal = await hg.seals.issue({
  sku:      "WATCH-OCEANIC-42",
  lot:      "LOT-0XF3",
  origin:   "Solingen, DE",
  nfc:      true,            // provision the embedded chip key
});
console.log(seal.serial); // HG-8842-7C19-A4D0

// 2. Verify a scan (challenge-response, not just a lookup)
const result = await hg.verify(scan.payload);
if (result.status === "VALID") grantWarranty(result.provenance);

NFC + QR dual mode — provision NTAG 424 DNA chips or fall back to a signed dynamic QR.
Chain-agnostic anchor — provenance hashes anchored on a public L2; full record stays portable.
Webhooks — get pinged on every VOID verdict, gray-market region hit, or duplicate scan.
Edge verify — sub-100 ms responses from 18 regions; works offline-first for line scanners.

05 Case studies

What the seal changed for three very different makers.

OCEANIC HOROLOGIE · Swiss watches

"Gray-market resales used to gut our warranty data. Now every watch carries its own provenance — resale fraud dropped 73% in one quarter."

— R. Vogt, Head of Brand Protection

NORDVACC PHARMA · cold-chain vaccines

"A pharmacist scans the vial and sees the full custody chain plus the cold-chain log. Falsified-medicine complaints went to zero across two markets."

— Dr. A. Lindqvist, Supply Integrity

TORQUEWORKS · aerospace fasteners

"Counterfeit titanium bolts are a safety nightmare. Hologuard's live-challenge seal made 'looks genuine' irrelevant — only a real chip passes audit."

— M. Okafor, Quality Director
