NfcManager

public final class NfcManager extends Object
High level manager used to obtain an instance of an {@link NfcAdapter}.

Use {@link android.content.Context#getSystemService(java.lang.String)} with {@link Context#NFC_SERVICE} to create an {@link NfcManager}, then call {@link #getDefaultAdapter} to obtain the {@link NfcAdapter}.

Alternately, you can just call the static helper {@link NfcAdapter#getDefaultAdapter(android.content.Context)}.
