General Information

This is a fork of the libnfc library that should work with the SCL3711 NFC reader/writer to write to cheap UUID writable MIFARE Classic cards. For more information about libnfc please see the original repository.

Installation

Make sure you’ve installed all dependencies to build libnfc. For example, on Debian, run sudo apt build-dep libnfc-bin.

Build from source

autoreconf -vis
./configure
make

Set udev rules

sudo cp contrib/udev/42-pn53x.rules /lib/udev/rules.d/

Blacklist pn533

Since Linux kernel version 3.1, two kernel-modules must not be loaded in order to use libnfc: "nfc" and "pn533". To prevent kernel from loading automatically these modules, you can blacklist them in a modprobe conf file. This file is provided within libnfc archive:

sudo cp contrib/linux/blacklist-libnfc.conf /etc/modprobe.d/blacklist-libnfc.conf

Usage

./utils/nfc-list # check if the dongle can be found
./utils/nfc-mfclassic r a dump.mfd # dump the card
./utils/nfc-mfclassic w a dump.mfd # write the dumped file

Troubleshooting

Binaries

If the tools fail to work properly, try installing libnfc from the Debian repository for the tools that don’t need to be patched (patching is only required to directly write to block 0x00, containing the UUID).

SCL3711

Libnfc cannot be used concurrently with the PCSC proprietary driver of SCL3711. Two possible solutions:

• Either you don't install SCL3711 driver at all
• Or you stop the PCSC daemon when you want to use libnfc-based tools

Blacklist

It might also be necessary to blacklist pn533_usb:

sudo modprobe -r pn533_usb
