/**
 * @name NFC
 * @description
 * The NFC plugin allows you to read and write NFC tags. You can also beam to, and receive from, other NFC enabled devices.
 *
 * Use to
 * - read data from NFC tags
 * - write data to NFC tags
 * - send data to other NFC enabled devices
 * - receive data from NFC devices
 *
 * This plugin uses NDEF (NFC Data Exchange Format) for maximum compatibilty between NFC devices, tag types, and operating systems.
 *
 * @usage
 * ```
 * import {NFC, Ndef} from 'ionic-native';
 *
 * let message = Ndef.textRecord('Hello world');
 * NFC.share([message]).then(onSuccess).catch(onError);
 *
 * ```
