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. Dart

import 'package:chilkat/chilkat.dart';

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

  final scmd = CkScMinidriver();

  // Reader names (smart card readers or USB tokens) can be discovered
  // via List Readers or Find Smart Cards
  final readerName = 'Alcor Micro USB Smart Card Reader 0';
  try {
    scmd.acquireContext(readerName);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // If we are successful, the name of the currently inserted smart card is available:
  final cardName = scmd.cardName;
  print('Card name: $cardName');

  // Also, the ATR of the inserted card is available (you will likely not need the ATR).
  print('ATR: ${scmd.atr}');

  // Also, the maximum number of key containers is readily available:
  print('Max number of key containers = ${scmd.maxContainers}');

  // Delete the context when finished with the card.
  try {
    scmd.deleteContext();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
  }

  // Sample output:

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