Welcome to PC/SC Relay. The purpose of PC/SC Relay is to relay a smart
card using an contact-less interface. Currently the following contact-less
backends:
- libnfc_
- OpenPICC_
Command APDUs are received with the contact-less interface and forwarded to an
existing smart card via PC/SC. The Response APDUs are then sent back via RFID.
You can use PC/SC Relay in combination with the :ref:`vicc` to completely
emulate an ISO/IEC 14443 smart card.
.. note::
This software can actually be used in a relay attack allowing full access
to the card. We discussed the impact especially on the `Relay attack
against the German ID card`_, but it generally concerns *all* contact-less
smart cards.

PC/SC Relay has the following dependencies:
- PC/SC middleware
- libnfc_
===============
Hints on libnfc
===============
PC/SC Relay links against libnfc_. Here is an example of how to get the standard
installation of the latter::
PREFIX=/tmp/install
LIBNFC=libnfc
svn co http://libnfc.googlecode.com/svn/trunk $LIBNFC
cd $LIBNFC
autoreconf -i
./configure --prefix=$PREFIX
make
make install
Building PC/SC Relay with libnfc_ is done best using :command:`pkg-config`. The file
:file:`libnfc.pc` should be located in ``$INSTALL/lib/pkgconfig``. Here is how to
configure PC/SC Relay to use it::
./configure PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
=========================
Hints on PC/SC middleware
=========================
A PC/SC middleware is included by default in most modern operating systems. On
Unix-like systems (Linux, OS X, Sun OS) it is realized by PCSC-Lite_. To
compile PC/SC Relay you will need to install the PCSC-Lite_ headers from
your distribution.
Windows also ships with a PC/SC middleware in form of the Winscard module.
Microsoft's developement environment Visual Studio includes all necessary data
for building PC/SC Relay.
