What Is a Polycarbonate Card?

A polycarbonate card is a smart or identification card manufactured using polycarbonate (PC) material instead of conventional PVC.

Polycarbonate is an engineering thermoplastic known for its high impact resistance, durability and dimensional stability. For secure card applications, PC can also be used as part of a multilayer card structure in which security elements, personalization features and other functional components are integrated into the card construction.

This makes polycarbonate suitable for projects where a card must provide more than basic printing and identification.

Typical applications include:

·Secure ID cards

·Government identification

·Electronic ID cards

·Employee ID cards

·Access control cards

·Healthcare identification

·RFID smart cards

·High-security authentication cards

Why Choose Polycarbonate Material for Secure Cards?

When a card is expected to remain in service for a long period, material selection becomes an important part of the security and reliability strategy.

Compared with conventional PVC card construction, polycarbonate can provide a combination of durability, impact resistance, thermal performance and compatibility with advanced personalization and security technologies.

Polycarbonate Material Benefits

For high-security identification projects, the advantage of polycarbonate is not simply the material itself. Its value comes from combining the PC substrate with appropriate printing, personalization and security technologies.

Polycarbonate Card vs PVC Card

The right material depends on the intended application.

PVC can be suitable for standard cards where cost, basic printing and short- or medium-term usage are the primary requirements.

Polycarbonate is better suited to projects where durability, personalization security and anti-counterfeit protection are major considerations.

The final choice should be based on the required security architecture, service environment, personalization method and project specifications.

What Security Features Can Be Integrated Into a Polycarbonate Card?

High-security PC cards can combine multiple visible, covert and machine-verifiable features rather than relying on a single anti-counterfeit method.

Depending on the project, the following technologies can be incorporated into the card design.

Optically Variable Device (OVD / DOVID)

OVD creates a changing visual effect when the card is tilted or viewed under different illumination conditions.

DOVID, or Diffractive Optically Variable Image Device, uses diffractive structures to create a dynamic image effect. Such technologies are widely associated with secure identification and document protection.

For high-security applications, DOVID can also be designed with additional visual or machine-verifiable characteristics. ICAO describes optically variable and diffractive features as important anti-copy technologies for secure identity and travel documents.

VDS – Visible Digital Seal

A Visible Digital Seal can combine visible security information with machine-verifiable data according to the project architecture.

It can be considered when a card requires both human inspection and digital verification.

OVI – Optically Variable Ink

Optically Variable Ink creates a visible colour-shifting effect when the card is tilted.

Depending on the ink specification, the visual effect can present a defined colour transition that is difficult to reproduce using conventional printing.

Iridescent Ink

Iridescent ink provides a continuous rainbow-like shimmer that changes with viewing angle.

It can be incorporated into security backgrounds and graphic elements to create an additional visual inspection layer.

Holographic Security Foil

Holographic security foil can create:

·3D visual effects

·Dynamic multi-channel images

·Microtext

·Latent security elements

·Angle-dependent optical effects

These features add another level of visual authentication and can be integrated into the overall card design.

MLI – Multiple Laser Image

MLI uses a lenticular structure and laser personalization to display different images depending on the viewing angle.

When the card is tilted vertically or horizontally, the image changes.

This makes MLI suitable for advanced personalization and secure identification projects.

CLI – Changeable Laser Image

CLI is another advanced laser personalization technology.

Different images appear at different viewing angles, making the feature suitable for applications requiring high-level visual authentication.

MLI and CLI can be integrated with a pre-laminated lenticular lens structure according to project requirements.

UV Fluorescent Ink

UV fluorescent markings are generally invisible under normal lighting conditions but become visible under ultraviolet illumination.

This creates a second verification layer that is difficult to identify through ordinary visual inspection.

Microtext

Microtext consists of extremely small characters that are difficult to reproduce accurately using conventional printing methods.

The text may require magnification for verification.

It can be used in security backgrounds, portraits, borders or other graphic elements.

Latent Image Printing

A latent image remains hidden during normal viewing and becomes visible only from a specific viewing angle.

This provides an additional visual authentication feature without significantly changing the normal appearance of the card.

Optically Variable Grating Image

Optically variable grating structures can create shifting or flashing optical patterns as the card is tilted.

They can be incorporated into security graphics to make unauthorized reproduction more difficult.

Thermochromic Ink

Thermochromic ink changes colour when exposed to a specified temperature variation and returns toward its original appearance as the temperature changes back.

This provides a temperature-responsive security feature for suitable applications.

Embossing

Embossing creates raised tactile patterns or characters on the card surface through controlled mechanical deformation.

Because the feature can be both seen and physically felt, it provides another inspection layer.

Infrared (IR) Ink

IR ink contains infrared-responsive pigments.

The security element may not be visible during normal inspection and can instead be detected using an appropriate infrared reader or inspection system.

Card Watermark

A card watermark can be incorporated into the polycarbonate core layer.

Under transmitted light, the watermark becomes visible while remaining difficult to reproduce through ordinary surface printing.

How Are Multiple Security Features Combined?

A secure PC card does not need to depend on one technology.

A stronger approach is to combine security technologies into multiple inspection levels.

For example:

Level 1 – Visible Inspection

Features that can be checked directly by the card holder or inspector:

·OVD / DOVID

·OVI

·Holographic foil

·Embossing

·Iridescent effects

·Latent images

Level 2 – Magnification / UV / Optical Inspection

Features requiring additional inspection:

·Microtext

·UV fluorescent ink

·Optically variable grating

·Specific latent features

Level 3 – Machine-Assisted Verification

Features requiring dedicated equipment:

·IR ink

·Machine-verifiable optical features

·VDS-related verification

·Selected DOVID technologies

·RFID/NFC-based electronic verification

This layered approach is consistent with secure-document design principles: ICAO notes that different security features can provide different visual, tactile and machine-verifiable protections, and that using a variety of features helps manage counterfeiting risk.

Can RFID Be Integrated Into a Polycarbonate Card?

Yes. Polycarbonate cards can integrate RFID or NFC technology to combine physical card security with electronic identification.

Depending on the application, the card can be customized with different chip technologies and communication requirements.

Possible applications include:

Chip selection should be based on the reader system, operating frequency, memory requirements, security architecture and intended application.

For an OEM project, it is recommended to provide the required chip model and system specifications during the quotation stage.
