What is Smart Card Software
Smart card software, known as Middleware, enables computer applications to talk to the computer chip on the smart card.
A smart card contains a gold computer chip that not only stores public key infrastructure (PKI) digital certificates and their associated private keys, but performs cryptographic functions (i.e., encryption and decryption) with those certificates and keys. The smart card reader provides the physical connection between the smart card's computer chip and your computer. The middleware is the communications link (e.g., translator) between applications on your computer and the specialized computer code located on the smart card chip.

Smart card middleware must be installed on your computer before you can use your HHS smart card ID badge to log on to a computer, digitally sign documents, or read encrypted email. Windows 7 and Vista has middleware built-in; however, built-in middlewmay not work with the new 128k PIV card and does not offer the additional functionality of the ActivClient middleware (e.g., ability to update/renew your certificates at your desktop).
ActivClient middleware may already be installed on your computer. On a Windows PC, ActivClient is installed if one of the following icons appears in the system tray:
or
when smart card is inserted in reader.
