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

// First, Chilkat recommends downloading the MGTEK Smartcard Minidriver Tool to get information 
// about your smartcard. 

// The tool can be downloaded from https://www.mgtek.com/smartcard

// --------------------------------------------------------------------------------------------------------
// 1. Select the smartcard as shown below and send Chilkat a screenshot of the basic smartcard information.
// --------------------------------------------------------------------------------------------------------
// 
// (image:https://example-code.com/images/mgtek_screenshot.jpg/endImage)
// 
// --------------------------------------------------------------------------------------------------------
// 2. Select the cmapfile (if present) as shown below and send Chilkat a screenshot of the CSP container map
// --------------------------------------------------------------------------------------------------------

// Chilkat provides functions to get information about the smartcard, and what it contains.
// Send Chilkat the output of the following source code:

scmd := CkScMinidriver_Create();

// Reader names (smart card readers or USB tokens) can be discovered
// via PCSC List Readers or PCSC Find Smart Cards
readerName := 'Alcor Micro USB Smart Card Reader 0';
success := CkScMinidriver_AcquireContext(scmd,readerName);
if (success = False) then
  begin
    Memo1.Lines.Add(CkScMinidriver__lastErrorText(scmd));
    Exit;
  end;

json := CkJsonObject_Create();
CkJsonObject_putEmitCompact(json,False);

// ------------------------------------------------------
// 3. Send Chilkat the JSON returned by GetCardProperties
// ------------------------------------------------------
success := CkScMinidriver_GetCardProperties(scmd,json);
if (success = False) then
  begin
    Memo1.Lines.Add(CkScMinidriver__lastErrorText(scmd));
    Exit;
  end;

// ------------------------------------------------------
// 4. Send Chilkat the JSON returned by GetCspContainerMap
// ------------------------------------------------------
