The technical specifications of PIV smartcards

The technical specifications of PIV smartcards: 

1. Chip Technology: - Contains a microprocessor chip, typically with at least 64KB of memory - Supports various cryptographic algorithms including RSA, ECC, AES, and SHA 

2. Biometric Data: - Stores two fingerprint templates - Uses ANSI/INCITS 378 standard for fingerprint minutiae data - May also include facial image data 

3. Digital Certificates: - Contains at least one X.509 digital certificate for authentication - May include additional certificates for digital signing and encryption - Certificates are typically issued by a federal or approved non-federal Certificate Authority 

4. Physical Characteristics: - Credit card sized (ID-1 format as per ISO/IEC 7810) - Made of durable plastic, designed to last 5-10 years - Includes anti-counterfeiting features like holograms or microprinting 

5. Communication Protocol: - Uses ISO/IEC 7816 for contact interface - Some cards also support contactless interface using ISO/IEC 14443 

6. Data Model: - Follows the NIST SP 800-73 specification - Organizes data into a standardized file structure 

7. Security Features: - Supports PIN protection (usually 6-8 digits) - May include a blocking feature after a set number of incorrect PIN attempts - Utilizes secure key storage and cryptographic operations within the chip
