    ; This example requires the Chilkat API to have been previously unlocked.
    ; See Global Unlock Sample for sample code.

    ; 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.
