electronic Cover inlays for electronic and biometric documents

For eID and ePassport applications, security is an absolute priority. Identity documents must protect sensitive biometric data while remaining durable, reliable and compliant with international standards. Linxens develops ultra-thin inlays and electronic covers that enable document manufacturers to integrate advanced layers of security directly into passports and electronic ID cards. Through innovative antenna design, secure chip integration and flexible inlay technologies, we support governments worldwide in delivering next-generation identity solutions.

What are electronic Cover Inlays?

An eCover inlay, also known as an ePassport inlay or electronic passport inlay, is an ultra-thin electronic module embedded into the passport cover.

It integrates:

  • A secure microchip (passport chip)

  • A contactless antenna

  • Flexible inlay layers

The electronic Cover transforms a traditional passport cover into a passport cover solution capable of securely storing and transmitting biometric data.

These digital passport inlays enable contactless communication with border control systems while ensuring high durability and tamper resistance.

What are eID Inlays?

An eID inlay is designed for integration into electronic ID cards and other secure credentials.

Unlike passport electronic covers, eID inlays are typically embedded into card bodies. They combine:

  • Secure chip modules

  • Antenna systems

  • Protective inlay cover structures

Electronic ID card and eID card solutions require extremely thin, flexible inlays to preserve card rigidity while protecting embedded electronics.

Linxens develops ultra-thin inlays tailored for both passport and card-based identity programs.

What are the technical features of electronic cover inlays?

Material composition

Electronic covers use specific paper substrates engineered to resist humidity, chemicals and mechanical stress. These materials protect the embedded electronics while preserving document flexibility.

Flexible inlays are designed to adapt to bending without damaging the chip or antenna.

Electronic components

Each electronic passport inlay integrates a secure passport chip that stores biometric data such as:

  • Facial image

  • Fingerprints

  • Personal identity data

The chip is mounted onto the antenna with precision bonding technologies ensuring long-term reliability.

RFID technology and anti-skimming

Electronic Cover and inlay structures incorporate RFID technology to enable contactless reading.

To prevent unauthorized skimming, electronic covers integrate shielding materials within the inlay structure. This protects biometric data from illegal scanning when the document is closed.

What are the benefits of electronic Cover and ePassport Inlays?

  • Tamper-Proofing

The inlay cover structure makes physical tampering immediately visible. Attempts to remove or damage the passport chip result in detectable alterations.

Protection of sensitive electronics

Ultra-thin inlays encapsulate delicate electronic components, protecting them from humidity, bending and wear over time.

  • Compliance with international standards

Linxens solutions comply with ICAO and global e-government requirements for biometric passports and electronic IDs.

  • Anti-Skimming

Integrated shielding materials protect sensitive data against unauthorized reading attempts.

Use cases for electronic Covers and Inlays

  • Biometric e-passports

Electronic Cover inlays power modern biometric e-passports used worldwide for secure border crossings.

  • National ID cards

eID inlays enable secure digital identity for electronic ID cards.

  • Access control

Secure identity documents can be integrated into access control systems.

  • Health cards

Electronic health cards rely on inlay technology to securely store patient data.

Conclusion

Electronic covers and inlays are foundational components of secure digital identity ecosystems. By combining flexible inlays, secure chips and anti-skimming technologies, Linxens supports governments in building robust e-government infrastructures.
