NFC Manager API provides access to NFC Events.

Required Header

#include <nfc.h>

Overview

The nfc manager api provides functions to connect nfc-server and register event listener

control connection with nfc-server.
register / deregister event listeners for detecting tag, ndef, llcp, secure element
set / unset tag filter to be listened only in case of specific tag.
