    // Chilkat recommends the following free tool for interactively examining the contents of your smart card
    // through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

    // Let's first look at our smart card before importing a private key.
    // Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

    

    // First let's load a private key into the Chilkat private key object.
    // (Chilkat provides the ability to load private keys from many different sources and formats.
    // this example loads from a PEM file.)

        Send CreateComObject of hoScmd
    End

    // First we need to acquire a context to the smart card in the reader where it is inserted.
    // Reader names (smart card readers or USB tokens) can be discovered
    // via List Readers or Find Smart Cards
    Move "Alcor Micro USB Smart Card Reader 0" To sReaderName

    // If successful, the name of the currently inserted smart card is available:
    Get ComCardName Of hoScmd To sTemp1
    Showln "Card name: " sTemp1

    // To import a private key, we'll need to be PIN authenticated.
    // For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
    Move "user" To sPinId
    Get ComPinAuthenticate Of hoScmd sPinId "0000" To iRetval

    // Let's import into the "key exchange" position in key container #7.
