The Gold Standard for Asset Identification and Tracking

Microdots for Asset Security and Identification

Our proprietary NanoTagDNA technology deploys microscopic nickel microdots — each chemically etched with a unique Security Identification Code — to provide irrefutable proof of ownership across every industry, worldwide.

Technology

What is a NanoTag?

An octagonal nickel microdot, 6–10 microns thin, carrying a physically etched Security Identification Code and an Optically Variable Device surface — virtually invisible, virtually indestructible.

NanoTags are made of nickel, octagon-shaped, 6–10 microns thin and 0.3 mm to 0.7 mm across. One side features a hologram-like nano image — technically an Optically Variable Device (OVD) — displaying changes of colour under different viewing angles. Unlike a real hologram, which appears as a meaningless grey mass under a microscope, NanoTags reveal fine branding detail and brilliant colour at 100× magnification.

The Security Identification Code (SIC) is etched physically through the body of the nickel tag. The same SIC repeats through thousands of NanoTags in each personalised batch, mixed with a proprietary UV-trace adhesive. Once dry, the encased NanoTags become resistant to water, most chemicals, and environments.

NanoTag's nickel substrate supersedes earlier plastic-based microdot technology. Plastic microdots begin deteriorating above 150°C and burn completely at 350°C. NanoTags withstand temperatures over 1,000°C without oxidising — even when adhesive burns away, the tags remain adhered to the surface with all information intact.

Core advantages

Why NanoTag outperforms every alternative

Four properties that make NanoTagDNA the only marking technology capable of providing legally admissible proof of ownership under any condition.

01

Microscopic concealment

At 0.3 mm, NanoTags are invisible to the naked eye. Thieves cannot find and remove all tags — a single surviving tag is sufficient to prove ownership in court.

02

Impossible to replicate

The SIC is physically etched through nickel, combined with a custom OVD nano-image. Protected by international patents and trade secrets, the technical barrier to counterfeiting is insurmountable.

03

Extreme durability

Nickel withstands over 1,000°C without oxidising. NanoTags survive fire, solvents, pressure washing, and decades of outdoor exposure that destroy every other marking technology.

04

Instant verification

The Micro-STR reader and app extracts SIC codes electronically in real time, checking them against an ownership database in the field without manual transcription.

Detection process

Finding and reading a NanoTag

Three steps from covert marking to court-admissible proof of ownership.

01

Locate with UV light

All NanoTag adhesives contain UV trace elements. Once dry, the adhesive is transparent and virtually invisible. A UV torch causes the trace elements to glow, immediately revealing where NanoTags have been applied.

02

Read with a microscope

Use a portable or digital microscope at 100× magnification to read the brand logo and SIC number from the tag surface. The Micro-STR custom reader automates this step, extracting the code electronically without manual recording.

03

Verify against database

The SIC is checked instantly against the ownership database, returning registered owner details. This provides irrefutable, legally admissible proof of ownership — for law enforcement, insurers, and warranty claims teams worldwide.

Industry solutions

Deployed across every sector

NanoTag technology is in active use or testing across industries where proof of ownership, theft deterrence, or anti-counterfeiting are critical.

Micro-STR system

Scene Text Recognition for microdots

An industry-leading microdot verification system that makes handheld microscopes and manual transcription entirely redundant.

Micro-STR handheld reader decoding a microdot code

The Micro-STR microdot verification system uses breakthrough Scene Text Recognition technology to decipher microdots as small as 0.3 mm — reading up to 17 characters on a 0.7 mm dot — and instantly checking the code against an ownership database to verify the owner of the asset.

Until now, identifying NanoTag codes required a handheld microscope magnifier and manual recording of the visible data. The Micro-STR Reader and App makes this process entirely electronic, enabling real-time data extraction anywhere — in the field, in difficult environments, without specialist laboratory equipment.

Deployable by law enforcement agencies, insurance and warranty claims investigators, and microdot manufacturers and their distributors worldwide. Available as a SaaS subscription for rapid integration into existing workflows.

Reads dots as small as 0.5 mm

STR technology deciphers microdots previously unreadable without laboratory equipment. A 1 mm dot yields up to 22 characters of SIC data in a single electronic pass.

Real-time electronic extraction

No manual transcription. The custom Micro-STR reader captures the code and transmits it to the database check in a single automated step.

Works in the field

Designed for difficult environments — roadside inspections, warehouse audits, crime scene investigations — where laboratory conditions are unavailable.

Live Mode and History log

The app provides a live scanning mode for active verification and a searchable history log for audit trail purposes, accessible via the Microdot STR Portal.

Global SaaS deployment

Rapid onboarding for law enforcement, insurers, and manufacturers worldwide without infrastructure changes or specialist hardware beyond the custom reader.

Durability

Built to outlast every other marking technology

The nickel substrate that makes NanoTags fundamentally superior to all plastic-based alternatives.

NanoTag — Nickel>1,000°C
Plastic microdots~350°C
RFID tags~200°C
Barcode / QR labels~80°C

NanoTag's nickel substrate supersedes all earlier microdot technology. Plastic-substrate microdots begin to deteriorate at temperatures above 150°C, leading to gradual loss of information, and burn completely at 350°C.

NanoTags withstand over 1,000°C without oxidising. Even when the adhesive burns away, the nickel tags remain adhered to the surface, retaining all information. Nickel's melting point is 1,453°C.

In a fire test heated to 1,000°C, tags remained clean, adhered, and fully legible — with all SIC data intact. Additionally, NanoTag High Security Fusion Tape embedded in woven labels withstands over 50 washing and drying cycles at temperatures up to 650°C.
