(Lianja) 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.

loScmd = createobject("CkScMinidriver")

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
lcReaderName = "Alcor Micro USB Smart Card Reader 0"
llSuccess = loScmd.AcquireContext(lcReaderName)
if (llSuccess = .F.) then
    ? loScmd.LastErrorText
    release loScmd
    return
endif

// If we are successful, the name of the currently inserted smart card is available:
lcCardName = loScmd.CardName
? "Card name: " + lcCardName

// Also, the ATR of the inserted card is available (you will likely not need the ATR).
? "ATR: " + loScmd.Atr

// Also, the maximum number of key containers is readily available:
? "Max number of key containers = " + str(loScmd.MaxContainers)

// Delete the context when finished with the card.
llSuccess = loScmd.DeleteContext()
if (llSuccess = .F.) then
    ? loScmd.LastErrorText
endif

// Sample output:

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