Our advisory is grounded in hands-on, production-floor knowledge of the full spectrum of physical security technologies — from substrate selection and security feature integration through to machine-readable personalisation and verification. This is not high-level advisory — it is deep technical expertise built over 32 years.
Every secure document programme requires a carefully selected combination of features across multiple categories. The right mix depends on threat model, budget, verification infrastructure and production capability — all of which we help you navigate.
| Category | Technology / Examples | Purpose | Verification |
|---|---|---|---|
| Optical | OVI (Optically Variable Ink), colour-shift inks, holograms, DOVID, kinegrams, diffractive foils | Immediate visual authentication — shifts colour or pattern under different viewing angles | Naked eye — Level 1 |
| Tactile | Intaglio printing, blind embossing, laser perforation, raised text, tactile laser engraving | Touch-based authentication — features that can be felt but not easily replicated by desktop printing | Touch — Level 1 |
| Substrate | Polycarbonate (PC), security paper, composite laminates, watermarks, security fibres, planchettes | Document integrity at the material level — tamper evidence and counterfeit resistance from the substrate itself | Visual / forensic — Level 1–3 |
| Covert (Trade) | UV fluorescence, IR transparent/absorbing inks, magnetic inks, microtext, guilloche patterns, micro-printing | Authentication requiring simple tools — UV lamps, magnifiers, magnetic readers | Tools required — Level 2 |
| Forensic | Taggants, chemical markers, forensic tracers, DNA markers, isotopic markers | Laboratory-level verification — unique to each issuing authority and invisible to counterfeiters | Laboratory — Level 3 |
| Digital / Electronic | RFID/NFC chip, laser-engraved biometric photo, encrypted data, PKI digital signatures, BAC/PACE/EAC protocols | Machine-readable authentication — chip-based data validation against globally distributed PKI infrastructure | Electronic readers — Level 2 |
| Personalisation | Laser engraving, thermal transfer, inkjet, colour laser, laser perforation ID photo | Binding personal data permanently to the document substrate — prevents substitution and alteration | Visual / electronic — Level 1–2 |
Robust document security programmes layer authentication across three levels — ensuring documents can be checked quickly at borders, in depth by trained officers, and definitively in forensic laboratories.
The choice of substrate and personalisation technology fundamentally determines a document's security level, durability and production cost profile. We advise on the right combination for your programme requirements.
The gold standard for modern national ID cards and passport datapages. Highly resistant to delamination, chemical attack and counterfeiting attempts.
Specially manufactured paper used for passport biographical pages and visa pages — incorporating multiple integral security features.
The primary personalisation method for polycarbonate documents. Creates permanent, tamper-proof personalisation data by carbonising the PC layers.
The electronic layer of ePassports and eID cards — storing biometric data cryptographically protected and globally verifiable.
Every programme we support is aligned to the relevant international standards — ensuring documents are globally interoperable, legally recognised and audit-ready from day one.
