For Google Chrome and Microsoft Edge, the API uses the Windows Certificate Store. For , you must manually add the PKCS#11 module ( cardos11.dll ) in the browser's "Security Devices" settings. Conclusion
At its core, the acts as the essential "translator" for Eviden (formerly Atos) smart cards. While the CardOS V5.5 operating system runs on the card itself to manage secure data storage and cryptographic operations, the API provides the necessary software hooks for your computer to talk to that card. Key Components
: Enables native integration with the Windows Base Smart Card Crypto Service Provider (Base CSP).
: Supports both contact and contactless (NFC/RFID) communication protocols (ISO 7816 and ISO 14443).
For data-intensive operations (e.g., syncing 500,000 product SKUs overnight), V5.5’s batched request processor reduces database round trips by 45%. This is a major win for logistics and retail implementations.
Enhanced support for RSA and Elliptic Curve Cryptography (ECC).
: Used for eID cards, employee badges, and secure document signing.
