NFC library for Ruby programming language

• Install libusb first. For Ubuntu run:

  apt-get install libusb-dev
  

• Download and install libnfc. Ruby-nfc currently works with 1.7.x branch

  # tar xjvf libnfc-1.7.1.tar.bz2
  # cd libnfc-1.7.1/
  # ./configure
  # make && make install
  

  Or if you're using Ubuntu Utopic Unicorn or higher version еnable "Universe" repository and then run:

  sudo apt-get install libfreefare-bin
  

  You may need to copy some system files from libnfc tarball anyway:

  sudo cp ./contrib/linux/blacklist-libnfc.conf /etc/modprobe.d/
  sudo cp ./contrib/udev/42-pn53x.rules /etc/udev/rules.d/
  

• Download and install libfreefare

  # tar xjvf libfreefare-0.4.0.tar.bz2
  # cd cd libfreefare-0.4.0/
  # ./configure && make && make install
  

• Look at lsusb output and make sure that your reader is present in 42-pn53x.rules

• Install appropriate driver for your NFC reader (if required)

• Reboot your system
