What Is the Biometric Fingerprint Card?

The Biometric Fingerprint Card is a next-generation smart card that integrates a fingerprint sensor and a secure microcontroller (secure element) directly into the card body. When you place your finger on the sensor, the fingerprint is matched internally (i.e., match-on-card) — meaning your biometric template never leaves the card.

Unlike tokens or external biometric readers, the Biometric Fingerprint Card remains your personal, portable authenticator. It can perform secure cryptographic operations, act as a hardware token, and supports FIDO2 and U2F protocols for online authentication.

Key Features & Biometric Security Card Highlights

Match-On-Card Biometric Verification

• The card captures your fingerprint via its built-in sensor.
• Biometric data is stored securely on the card’s secure element / microcontroller; no fingerprint template is uploaded to servers.
• Matching happens on-card — when you authenticate, the card itself verifies your fingerprint.
• This design provides maximum privacy and resistance to biometric data theft.

Dual-Interface: Contact + Contactless

• ISO 7816 Contact Interface: Compatible with standard smart-card readers used in banking, enterprise, and ID systems.
• ISO 14443 Contactless Interface: Supports NFC / NFC-enabled readers, making it ideal for mobile devices, access control readers, and contactless payments.

FIDO2 biometric card & U2F Protocol Support

• Built-in FIDO2 applet allows passwordless, phishing-resistant authentication through WebAuthn.
• Also supports U2F (Universal 2nd Factor) for two-factor authentication workflows.
• Use the card for secure login to cloud services, VPNs, enterprise systems, and web apps.

No Battery Required

• The Biometric Fingerprint Card is passive — it draws power from a smart-card reader or NFC field.
• Its lack of a battery ensures long-term reliability, durability, and low maintenance.

Durable, Standard Card Form Factor

• The card is ISO-ID-1 sized (like a standard credit card), making it easy to carry in your wallet.
• Built with rugged materials to withstand regular use, bending, and handling.

Secure Element & Cryptographic Strength

• Secure storage of keys and biometric templates in a tamper-resistant secure element.
• Supports cryptographic operations such as signing, key generation, and challenge-response authentication.
• Resistant to side-channel attacks and physical tampering.

How It Works: Enrollment & Authentication

Enrollment / Registration Process

1. The user places a finger on the in-card sensor.
2. The card’s MCU captures the fingerprint template and stores it internally, never sending the data outside.
3. For FIDO2 use, during registration with a service (e.g., your identity provider or web app), the card generates a public-private key pair.
   • The private key stays within the secure element of the card.
   • The public key is stored by the service.
4. The user confirms the biometric and card are bound, completing setup.

Authentication / Verification Process

1. When logging in, the service (e.g., a website) offers FIDO2 or U2F authentication.
2. You tap or insert the Biometric Fingerprint Card and place your finger on the sensor.
3. The card internally matches the fingerprint you provided with its stored template.
4. If the fingerprint matches, the card signs a cryptographic challenge from the service using its private key.
5. The signed response is sent to the service, which verifies it using your public key.
6. Authentication is complete — without ever transmitting raw fingerprint data.

Use Cases & Applications

The Biometric Fingerprint Card is versatile and can be deployed in many scenarios:

• Enterprise Authentication
  Use the card for logging into corporate systems, VPNs, laptops, and single sign-on (SSO) platforms. Its FIDO2 capability makes it perfect for passwordless or phishing-resistant workflows.
• Secure Payments & Banking
  Issue the card to customers for payment or banking authentication. The fingerprint ensures that only the legitimate cardholder can authorize transactions.
• Identity & Access Control
  Use the card for physical access to secure areas (like offices, data centers, or restricted rooms). Combined with card readers, it proves “something you have + something you are.”
• Government / Identity Verification
  Deploy as a national ID card, employee ID, or citizen identity card. The biometric element strengthens identity verification while preserving privacy via on-card biometric matching.
• Web Authentication (WebAuthn)
  Use FIDO2 functionality to log into cloud services and SaaS apps. Perfect for enterprises migrating to zero-trust or passwordless identity models.

Advantages Over Traditional Methods & Competing Devices

Comparison	Biometric Fingerprint Card	Traditional Smart Card / Token
Biometric Storage	On-card (match-on-card)	Often server-based or on external reader
Security	Fingerprint + cryptographic keys	PIN or password-based only
Privacy	High — biometric data never leaves card	Lower — biometric or login data often stored externally
Convenience	No PIN (fingerprint), slim card form factor	Tokens or readers may be bulkier; PINs required
Interfaces	Contact (ISO 7816) + Contactless (ISO 14443)	Depends on device (may only support one)

Security & Privacy Considerations

• Match-On-Card Technology: All fingerprint matching happens inside the card, ensuring that biometric templates never leave. This greatly reduces the risk of biometric data theft.
• Tamper-Resistant Secure Element: The card’s microcontroller securely protects cryptographic keys and fingerprint templates from physical attacks.
• Biometric Privacy: Since fingerprints are never uploaded to a server, you retain control over your biometric data.
• Phishing Resistance: With FIDO2, phishing attacks are foiled because the card only signs challenges from legitimate registered domains.
• Long-Term Reliability: No battery means less risk of power failure or maintenance.
• False Acceptance / Rejection: The card is designed to balance security and usability. While no biometric system is perfect, match-on-card mitigates many common risks.
• Compliance: Depending on deployment, the card can be used in systems requiring strong authentication (e.g., financial services, government), and supports industry-standard security frameworks.

Deployment & Integration

Infrastructure Requirements

To deploy the Biometric Fingerprint Card, you’ll typically need:

• Smart-card readers that support ISO 7816 (contact) and/or ISO 14443 (NFC)
• Software or middleware to communicate with the card and perform FIDO2 / U2F operations
• Identity provider (IdP) / authentication server capable of integrating with FIDO2
• Enrollment station (for first fingerprint registration)

Integration Scenarios

• Enterprise / SSO: Integrate with Microsoft Entra ID (Azure AD), Okta, Ping Identity, or other IdPs for secure login.
• Payment / Banking: Issue biometric cards as secure payment tokens; integrate with existing payment systems and card issuance platforms.
• Access Control: Use with door readers or card access control systems supporting contactless cards.
• Identity Programs: Deploy in organizations issuing ID or citizen cards; combine with identity management software.

User Onboarding

1. Distribute the card to the end-user.
2. Use an enrollment station or mobile setup (NFC reader) for the user to register fingerprints.
3. Guide the user to add the card to their online accounts (if using FIDO2) or access systems.
4. Optionally, enroll a backup biometric card for redundancy in case the primary card is lost.

Comparison With Other Biometric Authentication Devices

Compared with traditional biometric authentication devices:

• USB Biometric Tokens: Bulky, require a separate device, may need drivers. Biometric Fingerprint Card is flat, portable, and reader-agnostic.
• Smartphone Biometrics: Convenient, but tied to a specific device; not standardized for enterprise FIDO2 smart card workflows. The fingerprint card is device-agnostic.
• Smart Card + External Biometric Reader: Requires two components; more complex deployment. The fingerprint card is an all-in-one solution.
• Biometric Payment Cards (Consumer): Many payment biometric cards only store fingerprint templates on-card for verification in payments. Aftindia.in’s FEITIAN card adds the power of FIDO2 for identity and Biometric Authentication beyond just payments.
