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. VB.NET

Dim success As Boolean = False

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

Dim scmd As New Chilkat.ScMinidriver

' Reader names (smart card readers or USB tokens) can be discovered
' via List Readers or Find Smart Cards
Dim readerName As String = "Alcor Micro USB Smart Card Reader 0"
success = scmd.AcquireContext(readerName)
If (success = False) Then
    Debug.WriteLine(scmd.LastErrorText)
    Exit Sub
End If


' If we are successful, the name of the currently inserted smart card is available:
Dim cardName As String = 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 = " & scmd.MaxContainers)

' Delete the context when finished with the card.
success = scmd.DeleteContext()
If (success = False) Then
    Debug.WriteLine(scmd.LastErrorText)
End If


' Sample output:

' Card name: IDPrime MD T=0
' ATR: 3B7F96000080318065B0855956FB120FFE829000
' Max number of key containers = 20
