(VB.NET) ScMinidriver - Acquire Context with Smart Card or USB TokenSee more ScMinidriver ExamplesInitializes communication with the card inserted in the given reader (or a USB token). Reader names can be discovered via the SCard.ListReaders or SCard.FindSmartcards methods. If successful, the Atr and CardName properties will be set.
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code.
