IDpendant Smartcards (Chipkarten) are microprocessor-based smart cards used for identity verification, authentication, and access control in organizational environments. Each card contains a complete computing unit with CPU, RAM, ROM, and EEPROM, providing onboard cryptographic processing and secure storage for private keys, passwords, and digital certificates. **Authentication:** Smartcards support two-factor authentication (2FA) combining physical possession of the card with PIN knowledge, preventing credential copying, modification, or unauthorized use. They enable secure login to networks, PCs, and enterprise applications. **Security Mechanisms:** Cards employ cryptographic algorithms for encryption, ensuring confidentiality and integrity of stored data. Biometric methods can also be incorporated for additional protection. **Form Factors & Standards:** Available in contact-based, contactless, and hybrid/dual-interface variants. Cards conform to DIN ISO 7816 and are manufactured from PVC, ABS, PC, or PET materials. Physical customization options include holograms, magnetic stripes, and laser engraving. **Card Operating Systems:** Supports proprietary, Java™-based, and Multos-based card operating systems from multiple vendors. Technical specifications vary by EEPROM size (32k, 64k, 72k, etc.) and certifications including CC (Common Criteria), ITSEC, and FIPS. **Supported Card Manufacturers:** ATOS, Thales, Giesecke & Devrient, and NXP.
