ifdnfc-nci

PC/SC IFD Handler for PCSClite based on linux_libnfc-nci and ifdnfc (https://github.com/nfc-tools/ifdnfc).

This stack targets the NXP PN54x chipset. Extended APDUs are (mostly) supported, extensions for the German eID card protocol are implemented as well.

Requirements

Get and install the (forked) libnfc-nci library from https://github.com/StarGate01/linux_libnfc-nci/ , which works with the kernel driver from https://github.com/jr64/nxp-pn5xx .

Other requirements are gcc, cmake, pkg-config, pcsclite and make .

Building

mkdir -p build && cd build
cmake -DCMAKE_INSTALL_PREFIX=$(pwd)/../install ..
make

Installing

Place the ./install/lib/libifdnfc-nci.so file somewhere you like, e.g. /usr/lib/pcsc/drivers/serial/libifdnfc-nci.so

Append to /etc/reader.conf (or wherever your pcsc serial reader configuration is):

FRIENDLYNAME "NFC NCI"
LIBPATH      /usr/lib/pcsc/drivers/serial/libifdnfc-nci.so
CHANNELID    0

Hibernation issue

After hibernation / sleep wakeup, the NFC chip needs to re-initialized. An easy way to do this is to restart the PCSC daemon whenever the system wakes up (using a systemd oneshot service):

[Unit]
After=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target
Description=Wakeup PCSC after sleep

[Service]
ExecStart=systemctl restart pcscd.service
TimeoutStopSec=10
Type=oneshot

[Install]
WantedBy=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target
