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
- send raw commands (ISO 14443-3A, ISO 14443-3A, ISO 14443-4, JIS 6319-4, ISO 15693) to NFC tags
This plugin uses NDEF (NFC Data Exchange Format) for maximum compatibilty between NFC devices, tag types, and operating systems.

$ cordova plugin add phonegap-nfc
$ phonegap plugin add phonegap-nfc
Edit config.xml to install the plugin for PhoneGap Build.
<gap:plugin name="phonegap-nfc" source="npm" />
Windows Phone 8.1 should use the windows platform. The Silverlight based Windows Phone 8 code is no longer being maintained.
BlackBerry 7 support is only available for Cordova 2.x. For applications targeting BlackBerry 7, you may need to use an older version of phonegap-nfc.
See Getting Started and Getting Started BlackBerry 10for more details.
Reading NFC NDEF tags is supported on iPhone 7 and iPhone 7 Plus running iOS 11. To enable your app to detect NFC tags, the plugin adds the Near Field Communication Tag Reading capability in your Xcode project. You must build your application with XCode 9. See the Apple Documentation for more info.
Use nfc.addNdefListener to read NDEF NFC tags with iOS. Unfortunately, iOS also requires you to begin a session before scanning NFC tag. The JavaScript API contains two new iOS specific functions nfc.beginSession and nfc.invalidateSession.
You must call nfc.beginSession before every scan.
The initial iOS version plugin does not support scanning multiple tags (invalidateAfterFirstRead:FALSE) or setting the alertMessage. If you have use cases or suggestions on the best way to support multi-read or alert messages, open a ticket for discussion.
The nfc object provides access to the device's NFC sensor.

Send a file to another device via NFC handover.
var uri = "content://media/external/audio/media/175";
nfc.handover(uri, [onSuccess], [onFailure]);
var uris = [
"content://media/external/audio/media/175",
"content://media/external/audio/media/176",

- uri: A URI as a String, or an array of URIs.
- onSuccess: (Optional) The callback that is called when the message is pushed.
- onFailure: (Optional) The callback that is called if there was an error.
Function nfc.handover shares files to a NFC peer using handover. Files are sent by specifying a file:// or context:// URI or a list of URIs. The file transfer is initiated with NFC but the transfer is completed with over Bluetooth or WiFi which is handled by a NFC handover request. The Android code is responsible for building the handover NFC Message.
This is Android only, but it should be possible to add implementations for other platforms.
- Android
Stop sharing NDEF data via NFC handover.
nfc.stopHandover([onSuccess], [onFailure]);
- onSuccess: (Optional) The callback that is called when sharing stops.
- onFailure: (Optional) The callback that is called if there was an error.
Function nfc.stopHandover stops sharing data via peer-to-peer.

- Windows
- BlackBerry 10
Check if NFC is available and enabled on this device.
nfc.enabled(onSuccess, onFailure);
- onSuccess: The callback that is called when NFC is enabled.
- onFailure: The callback that is called when NFC is disabled or missing.
Function nfc.enabled explicitly checks to see if the phone has NFC and if NFC is enabled. If
everything is OK, the success callback is called. If there is a problem, the failure callback
will be called with a reason code.
The reason will be NO_NFC if the device doesn't support NFC and NFC_DISABLED if the user has disabled NFC.
Note: that on Android the NFC status is checked before every API call NO_NFC or NFC_DISABLED can be returned in any failure function.
Windows will return NO_NFC_OR_NFC_DISABLED when NFC is not present or disabled. If the user disabled NFC after the application started, Windows may return NFC_DISABLED. Windows checks the NFC status before most API calls, but there are some cases when the NFC state can not be determined.

iOS requires you to begin a session before scanning a NFC tag.
nfc.beginSession(success, failure);
Function beginSession starts the NFCNDEFReaderSession allowing iOS to scan NFC tags.
- success: Success callback function called when the session begins [optional]
- failure: Error callback function, invoked when error occurs. [optional]
nfc.beginSession();
- iOS
Invalidate the NFC session.

}]
}
Foreground dispatching and peer-to-peer functions are disabled when reader mode is enabled.
The flags control which tags are scanned. One benefit to reader mode, is the system sounds can be disabled when a NFC tag is scanned by adding the nfc.FLAG_READER_NO_PLATFORM_SOUNDS flag. See Android's NfcAdapter.enableReaderMode() documentation for more info on the flags.
- flags: Flags indicating poll technologies and other optional parameters
- readCallback: The callback that is called when a NFC tag is scanned.

The tag technology functions provide access to I/O operations on a tag. Connect to a tag, send commands with transceive, close the tag. See the Android TagTechnology and implementations like IsoDep and NfcV for more details. These new APIs are promise based rather than using callbacks.
const DESFIRE_SELECT_PICC = '00 A4 04 00 07 D2 76 00 00 85 01 00';
const DESFIRE_SELECT_AID = '90 5A 00 00 03 AA AA AA 00'
async function handleDesfire(nfcEvent) {
const tagId = nfc.bytesToHexString(nfcEvent.tag.id);
console.log('Processing', tagId);
try {
await nfc.connect('android.nfc.tech.IsoDep', 500);
console.log('connected to', tagId);
let response = await nfc.transceive(DESFIRE_SELECT_PICC);
ensureResponseIs('9000', response);
response = await nfc.transceive(DESFIRE_SELECT_AID);
ensureResponseIs('9100', response);
// 91a0 means the requested application not found
alert('Selected application AA AA AA');
// more transcieve commands go here
} catch (error) {
alert(error);
} finally {
await nfc.close();
console.log('closed');
}
}
function ensureResponseIs(expectedResponse, buffer) {

const error = 'Expecting ' + expectedResponse + ' but received ' + responseString;
throw error;
}
}
function onDeviceReady() {
nfc.addTagDiscoveredListener(handleDesfire);
}
document.addEventListener('deviceready', onDeviceReady, false);
Connect to the tag and enable I/O operations to the tag from this TagTechnology object.
nfc.connect(tech);
nfc.connect(tech, timeout);
Function connect enables I/O operations to the tag from this TagTechnology object. nfc.connect should be called after receiving a nfcEvent from the addTagDiscoveredListener. Only one TagTechnology object can be connected to a Tag at a time.
See Android's TagTechnology.connect() for more info.
- tech: The tag technology e.g. android.nfc.tech.IsoDep
- timeout: The transceive(byte[]) timeout in milliseconds [optional]
- Promise when the connection is successful
nfc.addTagDiscoveredListener(function(nfcEvent) {
nfc.connect('android.nfc.tech.IsoDep', 500).then(
() => console.log('connected to', nfc.bytesToHexString(nfcEvent.tag.id)),
(error) => console.log('connection failed', error)
);
})
- Android
Send raw command to the tag and receive the response.
nfc.transceive(data);
Function transceive sends raw commands to the tag and receives the response. nfc.connect must be called before calling transceive. Data passed to transceive can be a hex string representation of bytes or an ArrayBuffer. The response is returned as an ArrayBuffer in the promise.
See Android's documentation IsoDep.transceive(), NfcV.transceive(), MifareUltralight.transceive() for more info.
- data: a string of hex data or an ArrayBuffer
- Promise with the response data as an ArrayBuffer
// Promise style
nfc.transceive('90 5A 00 00 03 AA AA AA 00').then(
response => console.log(util.arrayBufferToString(response)),
error => console.log('Error selecting DESFire application')
)
// async await
const response = await nfc.transceive('90 5A 00 00 03 AA AA AA 00');
console.log('response =',util.arrayBufferToString(response));
- Android
Close TagTechnology connection.
nfc.close();
Function close disabled I/O operations to the tag from this TagTechnology object, and releases resources.
See Android's TagTechnology.close() for more info.
- none
- Promise when the connection is successfully closed
nfc.transceive().then(
() => console.log('connection closed'),
(error) => console.log('error closing connection', error);

The
ndefobject provides NDEF constants, functions for creating NdefRecords, and functions for converting data. See android.nfc.NdefRecord for documentation about constants
Represents an NDEF (NFC Data Exchange Format) data message that contains one or more NdefRecords. This plugin uses an array of NdefRecords to represent an NdefMessage.
Represents a logical (unchunked) NDEF (NFC Data Exchange Format) record.
- tnf: 3-bit TNF (Type Name Format) - use one of the TNF_* constants
- type: byte array, containing zero to 255 bytes, must not be null
- id: byte array, containing zero to 255 bytes, must not be null
- payload: byte array, containing zero to (2 ** 32 - 1) bytes, must not be null
The ndef object has a function for creating NdefRecords
var type = "text/pg",
id = [],
payload = nfc.stringToBytes("Hello World"),
record = ndef.record(ndef.TNF_MIME_MEDIA, type, id, payload);
There are also helper functions for some types of records
Create a URI record
var record = ndef.uriRecord("http://chariotsolutions.com");
Create a plain text record
var record = ndef.textRecord("Plain text message");
Create a mime type record
var mimeType = "text/pg",
payload = "Hello Phongap",
record = ndef.mimeMediaRecord(mimeType, nfc.stringToBytes(payload));
Create an Empty record
var record = ndef.emptyRecord();
Create an Android Application Record (AAR)
var record = ndef.androidApplicationRecord('com.example');
See ndef.record, ndef.textRecord, ndef.mimeMediaRecord, and ndef.uriRecord.
The Ndef object has functions to convert some data types to and from byte arrays.
See the phonegap-nfc.js source for more documentation.
Events are fired when NFC tags are read. Listeners are added by registering callback functions with the nfc object. For example nfc.addNdefListener(myNfcListener, win, fail);
- type: event type
- tag: Ndef tag
- tag
- ndef-mime
- ndef
- ndef-formatable
The tag contents are platform dependent.
id and techTypes may be included when scanning a tag on Android. serialNumber may be included on BlackBerry 7.
id and serialNumber are different names for the same value. id is typically displayed as a hex string nfc.bytesToHexString(tag.id).
Windows, Windows Phone 8, and BlackBerry 10 read the NDEF information from a tag, but do not have access to the tag id or other meta data like capacity, read-only status or tag technologies.
Assuming the following NDEF message is written to a tag, it will produce the following events when read.
var ndefMessage = [
ndef.createMimeRecord('text/pg', 'Hello PhoneGap')
];
{
type: 'ndef',
tag: {

}]
}
}
The raw contents of the scanned tags are written to the log before the event is fired. Use adb logcat on Android and Event Log (hold alt + lglg) on BlackBerry.
You can also log the tag contents in your event handlers. console.log(JSON.stringify(nfcEvent.tag)) Note that you want to stringify the tag not the event to avoid a circular reference.
Only Android and BlackBerry 7 can read data from non-NDEF NFC tags. Newer Windows Phones with NXP PN427 chipset can read non-NDEF tags, but can not get any tag meta data.
BlackBerry 7, BlackBerry 10 and many newer Android phones will not read Mifare Classic tags. Mifare Ultralight tags will work since they are NFC Forum Type 2 tags. Newer Windows 8.1 phones (Lumia 640) can read Mifare Classic tags.
Windows Phone 8, BlackBerry 10, and Windows read the NDEF information from a tag, but do not have access to the tag id or other meta data like capacity, read-only status or tag technologies.
Multiple listeners can be registered in JavaScript. e.g. addNdefListener, addTagDiscoveredListener, addMimeTypeListener.
On Android, only the most specific event will fire. If a Mime Media Tag is scanned, only the addMimeTypeListener callback is called and not the callback defined in addNdefListener. You can use the same event handler for multiple listeners.
For Windows, this plugin mimics the Android behavior. If an ndef event is fired, a tag event will not be fired. You should receive one event per tag.
On BlackBerry 7, all the events fire if a Mime Media Tag is scanned.
On Android, addTagDiscoveredListener scans non-NDEF tags and NDEF tags. The tag event does NOT contain an ndefMessage even if there are NDEF messages on the tag. Use addNdefListener or addMimeTypeListener to get the NDEF information.
Windows can scan non-NDEF (unformatted) tags using addTagDiscoveredListener. The tag event will not include any data.
On BlackBerry 7, addTagDiscoveredListener does NOT scan non-NDEF tags. Webworks returns the ndefMessage in the event.

This plugin uses the BlackBerry Invocation Framework to read NFC tags on BlackBerry 10. This means that you need to register an invoke target in the config.xml.
If your project supports multiple platforms, copy www/config.xml to merges/config.xml and add a rim:invoke-target tag. The invoke-target determines which tags your app will scan when it is running. If your application is not running, BlackBerry will launch it when a matching tag is scanned.
This sample configuration attempts to open any NDEF tag.
<rim:invoke-target id="your.unique.id.here">
<type>APPLICATION</type>
<filter>
<action>bb.action.OPEN</action>
<mime-type>application/vnd.rim.nfc.ndef</mime-type>
<!-- any TNF Empty(0), Well Known(1), MIME Media(2), Absolute URI(3), External(4) -->
<property var="uris" value="ndef://0,ndef://1,ndef://2,ndef://3,ndef://4" />
</filter>
</rim:invoke-target>
You can configure you application to handle only certain tags.
For example to scan only MIME Media tags of type "text/pg" use
<rim:invoke-target id="your.unique.id.here">
<type>APPLICATION</type>
<filter>
<action>bb.action.OPEN</action>
<mime-type>application/vnd.rim.nfc.ndef</mime-type>
<!-- TNF MIME Media(2) with type "text/pg" -->
<property var="uris" value="ndef://2/text/pg" />
</filter>
</rim:invoke-target>
Or to scan only Plain Text tags use
<rim:invoke-target id="your.unique.id.here">
<type>APPLICATION</type>
<filter>
<action>bb.action.OPEN</action>
<mime-type>application/vnd.rim.nfc.ndef</mime-type>
<!-- TNF Well Known(1), RTD T -->
<property var="uris" value="ndef://1/T" />
</filter>
</rim:invoke-target>
See the BlackBerry documentation for more info.
On Android, intents can be used to launch your application when a NFC tag is read. This is optional and configured in AndroidManifest.xml.
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED" />
<data android:mimeType="text/pg" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Note: data android:mimeType="text/pg" should match the data type you specified in JavaScript
We have found it necessary to add android:noHistory="true" to the activity element so that scanning a tag launches the application after the user has pressed the home button.
