This project contains a PC/SC wrapper and smartcard abstraction layer.
The project is provided as a self-contained Gradle project and should compile without problems.
A pre-built jar file is available in the "dist" folder.
On the most basic layer, we simply use a declarative approach to wrap PC/SC API functions. To work on this "abstraction" you can simply use de.intarsys.security.smartcard.pcsc.nativec._PCSC.
If you create this without parameter, the default library for the platform will be used.
There's a small abstract layer around de.intarsys.security.smartcard.pcsc.nativec._PCSC that allows for a little bit more readable code and also includes some indirections to ease life with 3rd-party libraries and workarounds for them.
In the "examples" directory you will find some demo code.
The most simple use case is
IPCSCContext context = PCSCContextFactory.get().establishContext();
List<IPCSCCardReader> readers = context.listReaders();
if (readers.isEmpty()) {
System.out.println("no reader found");
return;
}
for (IPCSCCardReader reader : readers) {
PCSCStatusMonitor monitor = new PCSCStatusMonitor(reader);
monitor.addStatusListener(new IStatusListener() {
@Override
public void onException(IPCSCCardReader reader, PCSCException e) {
e.printStackTrace();
}
@Override
public void onStatusChange(IPCSCCardReader reader,
PCSCCardReaderState cardReaderState) {
System.out.println("reader " + reader + " state "
+ cardReaderState);
}
});
}
To connect to a reader
// recommended use: create a new context for the connection
System.out.println("" + reader + " establish context");
IPCSCContext connectionContext = reader.getContext().establishContext();
System.out.println("" + reader + " connect");
IPCSCConnection connection = connectionContext.connect("example", reader.getName(), _IPCSC.SCARD_SHARE_SHARED,
_IPCSC.SCARD_PROTOCOL_Tx);
System.out.println("" + reader + " begin transaction");
connection.beginTransaction();
System.out.println("" + reader + " end transaction");
connection.endTransaction(_IPCSC.SCARD_LEAVE_CARD);
System.out.println("" + reader + " disconnect");
connection.disconnect(_IPCSC.SCARD_LEAVE_CARD);
System.out.println("" + reader + " dispose context");
connectionContext.dispose();
