Security Features

Making it easy for anyone to approve genuine banknotes with ultimate confidence

Agile security

For over 80 years – Portals have been pioneers of security features.  Trusted to help central banks and state print works design highly innovative security solutions that protect banknotes from counterfeiting.

Always in the pursuit of advancing our solutions we pioneered windowed security threads whilst more recently developing the process to embed wide stripes into paper for some of the highest denominations in the World.  Portals have always been at the forefront in the provision of counterfeit deterrent solutions.

Today our designers use holographic, colourshift and micro-optic technologies to deliver highly innovative security features.  Impressively clear movement, vibrant colour palettes and always durable to make a feature that performs regardless of denomination value and circulation conditions.

Clear Movement | High Durability | Built-in Security

Motus™

In a split second, know a banknote is genuine with Motus.

A micro-optic thread that delivers strong colour and clear movement for instant recognition.

Clear Movement

Market leading print technology creates surface printed images under 1D spherical lenses to produce an engaging and clear effect.

Easy Recognition

An attention grabbing thread that combines strong colour and distinctive movement that is hard to counterfeit.

High Durability

Maximise banknote life span with a covered lens structure for a thread that performs regardless of denomination value and circulation conditions.

Built-in Security

Available for full customisation in a range of colours and widths, with the possibility to add microtext and UV fluorescence.

Vibrant Colour | Bespoke Holographics | Security Enhanced

Prisma Duo™

Upgrade existing colourshift threads to Prisma Duo™.  A thread which combines the familiar and vibrant colour change of liquid crystal colourshift with the movement effects of customised holographics.

Prisma Duo™ makes a complex thread that is familiar to the general public.

Vibrant Colour

A wide spectrum of liquid crystal colourshift can be designed as foreground to the thread. A familiar security feature that is trusted in billions of banknotes Worldwide.

Bespoke Holography

Create a memorable holographic background that is bespoke and nuanced towards the banknote design

Fine Demetalisation

Seamlessly demetallise through the holographic and colour-shifting thread elements to add further complexity.

Thread Enhancement

Enhance the security of the thread including UV fluorescence, and magnetics including new third generation (Mag3) magnetic coding.

Versatile | Vibrant | Colour shifting

Prisma™

Prisma™ is a striking colour changing thread that is intuitive and easy to explain.  Building trust and confidence in a cost effective thread that has a unique brilliance.

Vibrant Colour

A wide spectrum of colours to choose from that can be designed to fit banknote aesthetics. Red to Green - Gold to Green - Gold to Orange - Green to Blue - Blue to Dark Blue - Dark Blue to Purple

Proven Durability

Robust and durable for hardworking denominations with a proven track record to last.

Thread Enhancement

Enhance the security of the thread including UV fluorescence, fine line demetalisation and magnetics including new third generation (Mag3™) magnetic coding.

Complexity | Verification | Covert

Mag3™

The latest generation of magnetic code, designed with a combination of different magnetic material layers.

It’s the complex overlaying of the magnetic layers which creates the security – A detailed and unique magnetic combination that delivers high levels of security counterfeiting deterrent.

Our magnetics are integrated into the manufacturing process when the thread is produced – ensuring durability regardless of circulation condition.

Mag3 is available on Janus, Prisma, Prisma Duo and holographic threads, foils and stripes.  Mag3 can also be produced on it’s own as a secondary feature.

Complex Coding

Customised codes, to guarantee a unique customer cash control system.

Machine Readability

Ensured machine readability with specific sensors that determine the legitimacy of the note.

Hidden Security

The magnetic coding capability of Mag3™ means that commercially available technologies are unable to detect this hidden feature.

Double Sided | Secure Window | In-Register

Vista™

Vista™ is a striking double-sided effect that is integrated into a stripe feature.  Registered to an aperture or window to create different effects dependent on transmitted or reflected light.

Double Sided Security

Strong forgery resistance through detailed, double sided, holography techniques that is positioned over a banknote aperture or window.

An Integrated Feature

Vista™ Can be combined with other holographic overt effects and covert features into a distinctive and beautiful holographic security feature.

Feature Enhancement

Available for full customization with integration of Multilevel™ demetalisation, fluorescent registered patterns and machine-readable features.

Colour Changing | Negative Text | Multiple Bands

Janus™

A dual or tri-colour banded thread, expertly combined with visual textures and text effects

Colour Changing

A wide range of pigment colour shifting effects. Multiple colours shift by changing the incidence of reflected light.

Negative Text

Negative text on the thread is perfectly at register - a strong counterfeit deterrent.

Multiple Bands

The dynamic layouts of Janus™ in either parallel, tramline or diagonal directions create bands of eye catching colour that complement and contrast with each other.

Big enough to trust, small enough to care.

We pride ourselves in our ability to be reliable and responsive, always enabling our customers to get the very most from working with us.
