| <p>Provides access to Near Field Communication (NFC) functionality, allowing applications to read |
| NDEF message in NFC tags. A "tag" may actually be another device that appears as a tag.</p> |

| <p>Here's a summary of the classes:</p> |
| |
| <dl> |
| <dt>{@link android.nfc.NfcManager}</dt> |
| <dd>This is the high level manager, used to obtain this device's {@link android.nfc.NfcAdapter}. You can |
| acquire an instance using {@link android.content.Context#getSystemService}.</dd> |
| <dt>{@link android.nfc.NfcAdapter}</dt> |
| <dd>This represents the device's NFC adapter, which is your entry-point to performing NFC |
| operations. You can acquire an instance with {@link android.nfc.NfcManager#getDefaultAdapter}, or |
| {@link android.nfc.NfcAdapter#getDefaultAdapter(android.content.Context)}.</dd> |
| <dt>{@link android.nfc.NdefMessage}</dt> |
| <dd>Represents an NDEF data message, which is the standard format in which "records" |
| carrying data are transmitted between devices and tags. Your application can receive these |
| messages from an {@link android.nfc.NfcAdapter#ACTION_TAG_DISCOVERED} intent.</dd> |
| <dt>{@link android.nfc.NdefRecord}</dt> |
| <dd>Represents a record, which is delivered in a {@link android.nfc.NdefMessage} and describes the |
| type of data being shared and carries the data itself.</dd> |
| </dl> |
