(Excel) ScMinidriver - Get Smartcard Properties

See more ScMinidriver Examples

Gets information about the smart card currently inserted in the reader (or USB token).

Note: This functionality was introduced in Chilkat v9.5.0.87.

Note: The ScMinidriver functionality is for Windows-only because ScMinidriver DLLs only exist on Windows. In the next version, Chilkat will be releasing a Pkcs11 class to support Linux, MacOSX, and possibly other operating systems.
