Two program exists for this simple demo:

1. NFC explore daemon

Requirements:

1) wiringPi  : installed by default on raspbian
2) libjason
	* git clone https://github.com/json-c/json-c.git
	* cd json-c
	* ./autogen.sh
	* ./configure
	* make
	* sudo make install
	* sudo nano /etc/ld.so.conf
		add the following line: /etc/local/lib
		ctrl+x to exit
	* sudo ldconfig

Build from source:

1) cd to "*/nfc/build" directory
2) cmake ../source
3) make
4) sudo ./nfc

2. NFC web server running on node.js

Requirements:

1) Node.js : wget http://node-arm.herokuapp.com/node_latest_armhf.deb && sudo dpkg -i node_latest_armhf.deb
2) cd to "*/nfc/server" directory
3) sudo npm install

Running web server

1) cd to "*/nfc/server"
2) sudo node nfcserver.js

That's it.

To test:

1) Open web browser and go to "http:<raspberrypi_ip_address>:3000"

Run at boot (assuming nfc binary is installed in "/usr/bin" and nfcserver.js and etc. is in "~/nfc/server":

On terminal:

1. sudo nano /etc/init/rc.local

    #!/bin/sh -e
    #rc.local
    
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will "exit 0" on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.
   
    # Print the IP address
    _IP=$(hostname -I) || true
    if [ "$_IP" ]; then
      printf "My IP address is %s\n" "$_IP"
    fi
   
    #Autorun
    sudo nfc &
    su pi -c 'sudo node ~/nfc/server/nfcserver.js < /dev/null  &'
    exit 0
   

exit and reboot pi!

Regards.
