-# nfc-binding
-Binding to handle NFC devices and tags.
-It currently use the libnfc, but we would like to support neard.
-Unfortunatly, neard seem not mature enough right now.
+# NFC Service
-# Devices and Tags compatibilities
+## Overview
-Those tags were tested with both SCL3711 (pn533) and ACS122U (pn532).
-ACS122U is currently not working using neard and have also some issues with libnfc.
-Expect random error, but seem to stay stable and working.
+NFC service uses the respective libnfc package to detect the presence of NFC tags and singal via an event

+## Events
-# UDev rules
-
-You may want to add some UDev's rule for nfc device to make things easier.
-You can put those lines into /etc/udev/rules.d/99-nfc.rules
-```Shell
-ACTION!="add", GOTO="nfc_pn53x_end"
-
-# Advanced Card Systems, Ltd ACR122U
-ATTRS{idVendor}=="072f", ATTRS{idProduct}=="2200", MODE="0666", SYMLINK+="nfc%n"
-
-# SCM Microsystems, Inc. SCL3711-NFC&RW
-ATTRS{idVendor}=="04e6", ATTRS{idProduct}=="5591", MODE="0666", SYMLINK+="nfc%n"
-
-LABEL="nfc_pn53x_end"
-```
-
-# Kernel module
-The SCL3711 is supported by the kernel and neard, so it takes the device and prevent the libnfc to use it.
-If you have an error saying that the device is busy, it's probably the reason why.
-
-You have to unload nfc kernel modules to get it work using libnfc.
-```ShellSession
-root@localhost# rmmod pn533_usb
-root@localhost# rmmod pn533
-root@localhost# rmmod nfc
-```
-
-To make it permanent you can add this file: /etc/modprobe.d/blacklist-nfc.conf
-```
-blacklist nfc
-blacklist pn533
-blacklist pn533_usb
-```
-
-# Compilation option
-
-* USE_LIBNFC - Enable or disable the 'libnfc' usage. Default is ON.
- * LIBNFC_POLL_ALL Enable all modulation when polling. Default is OFF.
- * LIBNFC_POLL_NMT_ISO14443A - Enable ISO-14443A modulation when polling. Default is ON.
- * LIBNFC_POLL_NMT_ISOJEWEL - Enable ISO-JEWEL modulation when polling. Default is OFF.
- * LIBNFC_POLL_NMT_ISO14443B - Enable ISO-14443B modulation when polling. Default is OFF.
