Animated effect
A4ID™ in motion.

The animated effect plays on a loop to show how the A4ID™ element behaves when the document is tilted. The video is presented as a product demonstration, not as a decorative digital transition.

Striking Visual Effects
Dynamic optical properties engineered for recognition.

The true signature of A4ID™ lies in its unique optical properties. Explore the dynamic visual effects, engineered to combine unmatched creative freedom with high-level security.

A4ID animate effect
01
Animate

Tilting the document triggers a continuous sequence of images, creating a smooth visual animation.

A4ID switch effect
02
Switch

Tilting the document reveals a crisp, instant transition between two distinct images or data sets.

A4ID grow effect
03
Grow

Tilting the document creates a dynamic optical illusion, making the visual element appear to expand or shrink.

A4ID movement effect
04
Movement

Tilting the document generates the clear illusion of a graphic element shifting across the secured surface.

A4ID rotation effect
05
Rotation

Tilting the document creates a striking visual illusion, making a graphic element appear to smoothly rotate on its own axis.

A Multi-Layered Architecture
Beyond the Surface: A Multi-Layered Architecture

Beneath its dynamic visual effects, A4ID™ integrates a comprehensive suite of structural security elements to prevent forgery and tampering.

Multi-Part Patch Design

A4ID™ can be composed of multiple, independent segments of varying sizes. Its dynamic visual effects remain flawlessly sharp and fully visible.

Security Slits & Micro-Perforations

A4ID™ can be structurally customized with extreme precision, allowing for the inclusion of security slits (for example, tracing the intricate rivers of a country map) and ultra-fine micro-perforations (such as embedded letters).

Micro & Nano Texts

A4ID™ can incorporate micro and nano texts (160µm & 20µm) that are easily verifiable under a standard magnifying glass.

Protect personalized data

A4ID™ is fully compatible with standard personalization as laser engraving or inkjet impression. This allows for the secure, unalterable binding of personalized data directly onto the physical optical element, creating a definitive link between the document and its holder.

Clear Window Integration

Designed for integration into transparent document windows, the A4ID™ dynamic movements and visual effects are visible from both the front and reverse sides, enabling quick, intuitive, and dual-sided visual authentication.

Seamless Artwork Integration
Seamless Artwork Integration

The ultimate flexibility in shape customization, combined with striking dynamic visual effects, allows A4ID™ to merge flawlessly into the document’s overall design.

Rather than appearing as an isolated patch, it interacts seamlessly with traditional background printing.

Compatible With All Substrates
A Technology Compatible With All Substrates

Engineered for the field: A4ID™ was developed alongside frontline professionals, such as the Venice Police and the Romanian Frontliners Association, amongst others, ensuring it meets the most demanding operational needs.

Polycarbonate vertical ID card security features
Embedded into Polycarbonate

A4ID™ can be embedded in the PC structure as an element on the reverse side of the front overlay.

Birth certificate paper simulation with A4ID
On or On/In Paper

A4ID™ can be applied on the surface of paper; or as a windowed thread: woven into paper.

A4ID passport cover optical element simulation
On Passport Covers

A4ID™ can be applied to the cover of a passport, regardless of the material it is made of (TPU, fabric or paper).
