(C# UWP/WinRT) ScMinidriver - Acquire Context with Smart Card or USB Token

See more ScMinidriver Examples

Initializes 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.

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.

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

Chilkat.ScMinidriver scmd = new Chilkat.ScMinidriver();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
string readerName = "Alcor Micro USB Smart Card Reader 0";
bool success = scmd.AcquireContext(readerName);
if (success == false) {
    Debug.WriteLine(scmd.LastErrorText);
    return;
}

// If we are successful, the name of the currently inserted smart card is available:
string cardName = scmd.CardName;
Debug.WriteLine("Card name: " + cardName);

// Also, the ATR of the inserted card is available (you will likely not need the ATR).
Debug.WriteLine("ATR: " + scmd.Atr);

// Also, the maximum number of key containers is readily available:
Debug.WriteLine("Max number of key containers = " + Convert.ToString(scmd.MaxContainers));

// Delete the context when finished with the card.
success = scmd.DeleteContext();
if (success == false) {
    Debug.WriteLine(scmd.LastErrorText);
}

// Sample output:

// Card name: IDPrime MD T=0
// ATR: 3B7F96000080318065B0855956FB120FFE829000
// Max number of key containers = 20
