/**
 * @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) { }
 *
 * ...
 *
 * this.nfc.addNdefListener(() => {
 *   console.log('successfully attached ndef listener');
 * }, (err) => {
 *   console.log('error attaching ndef listener', err);
 * }).subscribe((event) => {
 *   console.log('received ndef message. the tag contains: ', event.tag);
 *   console.log('decoded tag id', this.nfc.bytesToHexString(event.tag.id));
 *
 *   let message = this.ndef.textRecord('Hello world');
 *   this.nfc.share([message]).then(onSuccess).catch(onError);
 * });
 *
 * ```
