The PKI, also known as Public Key Infrastructure, is adopted widely in strong authentication applications. Due to sensitive data, such as private keys, are very important to the PKI system, high security smart cards are normally selected as the carrier to perform the role.

Feitian's PKI card is specially designed for PKI-based applications, as it is obvious that the combination of smart card technology with public key infrastructure does provide a greater and stronger level of protection against hackers than a stand-alone public key system. All sensitive credentials and private keys are stored inside the smart card chip and cannot be accessed from outside, thus reaching the ultimate security for intranet, extranet, and Internet applications, including secure access, authentication and data transmission through encryption technology as well as physical access and other extensively used applications.
