What makes EM-ID Gold™ different from existing authentication methods?
+
Existing methods — serial numbers, assay certificates, holograms, QR codes, and XRF purity tests
verify composition and branding only. They cannot prove that a specific physical bar is the same
one originally produced. EM-ID Gold™ is the first system that authenticates the metal itself,
capturing the unique electromagnetic microstructure formed during casting. No external identifier
can be forged or transferred because the identity lives inside the metal.
Does the fingerprinting process alter the gold bar or affect its composition?
+
No. The electromagnetic fingerprinting process is entirely non-destructive. It uses controlled
magnetic fields to read the bar's internal microstructure no drilling, no chemical treatment,
no surface contact beyond the mechanical positioning cradle. The bar's composition, weight,
purity, and all physical properties remain completely unchanged, maintaining full compatibility
with LBMA Good Delivery standards.
Can the fingerprint be copied or spoofed by counterfeiters?
+
No. The micro-crystalline structure of cast gold is formed by a stochastic process that is
physically unrepeatable without remelting the bar. Any remelting or recasting creates an entirely
new fingerprint — which will immediately fail verification against the original registered profile.
The three-dimensional, multi-axis nature of the fingerprint means a counterfeiter cannot reproduce
internal structure from external measurements alone.
How long does fingerprinting and verification take?
+
Manufacturing-stage fingerprinting takes seconds per bar and is designed to integrate seamlessly
alongside existing casting workflows without interrupting throughput. Verification scans at vaults,
dealers, or audit points are also completed within seconds — returning a clear match/no-match result
and logging the event automatically to the chain-of-custody audit trail in the cloud registry.
Will EM-ID Gold™ work with our existing Shopify / Amazon / marketplace setup?
+
The platform integrates via secure API channels with existing ERP, inventory, and marketplace
systems. The fingerprinting station operates independently of casting equipment and requires no
changes to refining processes, bar specifications, or compliance workflows. For vault operators
and dealers, the portable verification scanner connects to the central registry over an encrypted
API without requiring any changes to existing inventory management systems.
What is the technology readiness level and timeline to commercial deployment?
+
The technology is at the pre-commercial prototype stage with architecture fully designed and
induction sensing, multi-axis acquisition, signal processing, and registry components developed.
The development roadmap runs 12 months: scientific validation (Months 1–3), prototype hardware
(Months 4–6), identity registry software (Months 6–8), MVP integration (Months 8–10), and pilot
manufacturing deployment (Months 10–12). Revenue generation begins at Month 6 following the
first pilot client onboarding.
Is intellectual property protection in place?
+
Yes. A formal prior art search across the Patseer international patent database using ten
structured queries confirmed no existing solution discloses all six key elements of the
EM-ID Gold™ system. Elements B (Recast Integrity Engine), C (Cooling-Rate Microsegregation
Analyser), and D (Signature Persistence Model) have no coverage in any prior art. A UK patent
application covering the manufacturing-stage fingerprinting process is targeted as a Phase 1
deliverable. Signal-processing algorithms and calibration routines are protected separately as
trade secrets.
