    // This example requires the Chilkat API to have been previously unlocked.

    // 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..
    // Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.

    // 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
