/**
 * @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
 * ```typescript
 * import { NFC, Ndef } from '@ionic-native/nfc/ngx';
 *
 * constructor(private nfc: NFC, private ndef: Ndef) { }
 *
 * ...
 *
 * // Read NFC Tag - Android
 * // Once the reader mode is enabled, any tags that are scanned are sent to the subscriber
 *  let flags = this.nfc.FLAG_READER_NFC_A | this.nfc.FLAG_READER_NFC_V;
 *  this.readerMode$ = this.nfc.readerMode(flags).subscribe(
 *      tag => console.log(JSON.stringify(tag)),
 *      err => console.log('Error reading tag', err)
 *  );
 *
 * // Read NFC Tag - iOS
 * // On iOS, a NFC reader session takes control from your app while scanning tags then returns a tag
 * try {
 *     let tag = await this.nfc.scanNdef();
 *     console.log(JSON.stringify(tag));
 *  } catch (err) {
 *      console.log('Error reading tag', err);
 *  }
 *
 * ```
 *
