``` *- * Free/Libre Near Field Communication (NFC) library * * Libnfc historical contributors: * Copyright (C) 2009 Roel Verdult * Copyright (C) 2009-2015 Romuald Conty * Copyright (C) 2010-2012 Romain Tarti¨re * Copyright (C) 2010-2013 Philippe Teuwen * Copyright (C) 2012-2013 Ludovic Rousseau * Additional contributors: * See AUTHORS file -* ``` General Information =================== libnfc is a library which allows userspace application access to NFC devices. The official web site is: http://www.nfc-tools.org/ The official forum site is: http://www.libnfc.org/community/ The official development site is: https://github.com/nfc-tools/libnfc Important note: this file covers POSIX systems, for Windows please read README-Windows.md Requirements ============ Some NFC drivers depend on third party software: * pn53x_usb & acr122_usb: - libusb-0.1 http://libusb.sf.net * acr122_pcsc: - pcsc-lite http://pcsclite.alioth.debian.org/ The regression test suite depends on the cutter framework: http://cutter.sf.net Installation ============ See the file `INSTALL` for configure, build and install details. Additionnally, you may need to grant permissions to your user to drive your device. Under GNU/Linux systems, if you use udev, you could use the provided udev rules. e.g. under Debian, Ubuntu, etc. sudo cp contrib/udev/93-pn53x.rules /lib/udev/rules.d/ Under FreeBSD, if you use devd, there is also a rules file: contrib/devd/pn53x.conf. Configuration ============= In order to change the default behavior of the library, the libnfc uses a configuration file located in sysconfdir (as provided to ./configure). A sample commented file is available in sources: libnfc.conf.sample If you have compiled using: ./configure --prefix=/usr --sysconfdir=/etc you can make configuration directory and copy the sample file: sudo mkdir /etc/nfc sudo cp libnfc.conf.sample /etc/nfc/libnfc.conf To configure multiple devices, you can either modify libnfc.conf or create a file per device in a nfc/devices.d directory: sudo mkdir -p /etc/nfc/devices.d printf 'name = "My first device"\nconnstring = "pn532_uart:/dev/ttyACM0"\n' | sudo tee /etc/nfc/devices.d/first.conf printf 'name = "My second device"\nconnstring = "pn532_uart:/dev/ttyACM1"\n' | sudo tee /etc/nfc/devices.d/second.conf How to report bugs ================== To report a bug, visit https://github.com/nfc-tools/libnfc/issues and fill out a bug report form. If you have questions, remarks, we encourage you to post this in the developers community: http://www.libnfc.org/community Please make sure to include: * The version of libnfc * Information about your system. For instance: - What operating system and version - For Linux, what version of the C library And anything else you think is relevant. * A trace with debug activated. Reproduce the bug with debug, e.g. if it was: $ nfc-list -v run it as: $ LIBNFC_LOG_LEVEL=3 nfc-list -v * How to reproduce the bug. Please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded. * If the bug was a crash, the exact text that was printed out when the crash occured. * Further information such as stack traces may be useful, but is not necessary. Patches ======= Patches can be posted to https://github.com/nfc-tools/libnfc/issues If the patch fixes a bug, it is usually a good idea to include all the information described in "How to Report Bugs". Building ======== It should be as simple as running these two commands: ./configure make Troubleshooting =============== Touchatag/ACR122: ----------------- If your Touchatag or ACR122 device fails being detected by libnfc, make sure that PCSC-lite daemon (`pcscd`) is installed and is running. If your Touchatag or ACR122 device fails being detected by PCSC-lite daemon (`pcsc_scan` doesn't see anything) then try removing the bogus firmware detection of libccid: edit libccid_Info.plist configuration file (usually `/etc/libccid_Info.plist`) and locate `ifdDriverOptions`, turn `0x0000` value into `0x0004` to allow bogus devices and restart pcscd daemon. ACR122: ------- Using an ACR122 device with libnfc and without tag (e.g. to use NFCIP modes or card emulation) needs yet another PCSC-lite tweak: You need to allow usage of CCID Exchange command. To do this, edit `libccid_Info.plist` configuration file (usually `/etc/libccid_Info.plist`) and locate `ifdDriverOptions`, turn `0x0000` value into `0x0001` to allow CCID exchange or `0x0005` to allow CCID exchange and bogus devices (cf previous remark) and restart pcscd daemon. Warning: if you use ACS CCID drivers (acsccid), configuration file is located in something like: `/usr/lib/pcsc/drivers/ifd-acsccid.bundle/Contents/Info.plist` 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 PN533 USB device on Linux >= 3.1: --------------------------------- Since Linux kernel version 3.1, a few kernel-modules must not be loaded in order to use libnfc : "nfc", "pn533" and "pn533_usb". 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 Proprietary Notes ================= FeliCa is a registered trademark of the Sony Corporation.
