#NFC-master
1.Android CardReader Sample
===================================

This sample demonstrates how to implement a low-level NFC card reader, for reading cards
that do not contain NDEF or Android Beam data. This sample is designed to read the virtual
loyalty card implemented in the "CardEmulation" sample.


In particular, this sample demonstrates how to disable Android Beam, select which AIDs the
reader is interested, and establish communication with the card

2.Android CardEmulation Sample
===================================

This sample demonstrates how to emulate an NFC card, using the "host card emulation"
feature added in Android 4.4. This sample makes the device appear as a loyalty card
whenever the screen is on and the user taps their device on an appropriately configured
NFC reader.

The "CardReader" sample can be used to read the loyalty card implemented in this sample.

3.Android NfcProvisioning Sample
===================================

This sample demonstrates how to use NFC to provision a new device with a device owner. Device owner
is a specialized type of device administrator that can control device security and configuration.
This sample itself is not a device owner, but it is a programming app that sends NFC message to an
unprovisioned peer device and tells it to set up the specified device owner app.

Introduction
------------

NFC Provisioning app is nothing but an ordinary Android Beam app that just sends out provisioning
values to the peer device. This sample uses the values below.

* [EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME] - The package name of the mobile device management
  application that will be set as the profile owner or device owner.
* [EXTRA_PROVISIONING_LOCALE] - The Locale that the device will be set to.
* [EXTRA_PROVISIONING_TIME_ZONE] - The time zone AlarmManager that the device will be set to.
* [EXTRA_PROVISIONING_WIFI_SSID] - The ssid of the wifi network that should be used during nfc
  device owner provisioning for downloading the mobile device management application.
* [EXTRA_PROVISIONING_WIFI_PASSWORD] - The password of the wifi network in
  EXTRA_PROVISIONING_WIFI_SSID.

Store values in an instance of Properties. Get a byte array representation of the Properties using
ByteArrayOutputStream. Create an NdefRecord with the MIME type of
[DevicePolicyManager.MIME_TYPE_PROVISIONING_NFC][1]. Use [NfcAdapter#setNdefPushMessage][2] to set
the NdefMessage as the message to be sent.
