The @PACKAGE_NAME@ forwards a locally present PC/SC smart card reader as a
standard USB CCID reader. @PACKAGE_NAME@ can be used as trusted intermediary
enabling secure PIN entry and PIN modification. In combination with the |libnpa|
also |PACE| can be performed by the emulator.
If the machine running :command:`ccid-emulator` is in USB device mode, a local
reader is forwareded via USB to another machine. If in USB host mode, the USB
CCID reader will locally be present.

===============

Without the |libnpa| the @PACKAGE_NAME@ needs the OpenSC components to be
installed (especially :file:`libopensc.so`). Here is an example of how to get
the standard installation of OpenSC without |PACE|::
PREFIX=/tmp/install
OPENSC=opensc
svn co http://www.opensc-project.org/svn/opensc/trunk $OPENSC
cd $OPENSC
autoreconf -i
VSMARTCARD=vsmartcard
git clone git://vsmartcard.git.sourceforge.net/gitroot/vsmartcard $VSMARTCARD
cd $VSMARTCARD/ccid/src/opensc
autoreconf --verbose --install
./configure --prefix=$PREFIX
make
make install
make install && cd -
Now :file:`libopensc.so` should be located in ``$PREFIX/lib``. Here is how to
configure the USB CCID Emulator to use it::
configure the @PACKAGE_NAME@ to use it::
./configure OPENSC_LIBS="-L$PREFIX/lib -lopensc"
cd $VSMARTCARD/ccid
./configure --prefix=$PREFIX OPENSC_LIBS="-L$PREFIX/lib -lopensc"
make install && cd -
If you want |PACE| support for the emulated smart card reader the process is
similar. Install |libnpa| and it should be recognized automatically by the
:file:`configure` script.

Usage
*****
The USB CCID Emulator has various command line options to customize the appearance
on the USB host. In order to run the USB CCID Emulator GadgetFS must be loaded
and mounted. The USB CCID Emulator is compatible with the unix driver libccid_
and the `Windows USB CCID driver
<http://msdn.microsoft.com/en-us/windows/hardware/gg487509>`_. To initialize
|PACE| using the PC/SC API you need to patch libccid_ (see :file:`patches`).
