This is a fork from PhoneGap NFC Plugin 1.0.3
You can use this plugin with the ionic-native NFC provider:
npm i @ionic-native/nfc
Note: the iOS method beginNDEFSession
is not referenced in @ionic-native/nfc
. In order to call this method within an Ionic project, you need to declare it within your typescript file:
declare var nfc: Any;
nfc.beginNDEFSession(success, failure);
The current plugin comes with a protocol that allows to use NFC ISO15693 compatible devices to communicate with IoTize products.
see Communication protocol for more informations
Using cordova config-file node, you may edit AndroidManifest.xml file when adding the android platform. Copy the following snippet and add it inside the <platform name="android">
node of your project's config.xml file:
<config-file parent="/manifest/application/activity[@android:name='MainActivity']" target="app/src/main/AndroidManifest.xml" xmlns:android="http://schemas.android.com/apk/res/android">
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="application/YOUR_APPLICATION_PACKAGE" />
</intent-filter>
</config-file>
Replace YOUR_APPLICATION_PACKAGE according to your application and IoTize tap configuration.
The NFC plugin allows you to read and communicate with IoTize NFC Taps.
This plugin uses NDEF (NFC Data Exchange Format) and ISO15693 custom commands

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 iOS specific function nfc.beginNDEFSession and nfc.invalidateNDEFSession
You must call nfc.beginNDEFSession before every scan.
With iOS 13, Apple opened its NFC API and allowed communication with ISO15693 tags.
Use nfc.connect to begin a NFC communication session in your iOS app. you may then use the nfc.transceive method to exchange, and then close the session with nfc.close
The nfc object provides access to the device's NFC sensor.
- nfc.addNdefListener
- nfc.addMimeTypeListener
- nfc.enabled
- nfc.showSettings
- nfc.beginNDEFSession
- nfc.invalidateNDEFSession
Registers an event listener for any NDEF tag.
nfc.addNdefListener(callback, [onSuccess], [onFailure]);
- callback: The callback that is called when an NDEF tag is read.
- onSuccess: (Optional) The callback that is called when the listener is added.
- onFailure: (Optional) The callback that is called if there was an error.
Function nfc.addNdefListener
registers the callback for ndef events.
A ndef event is fired when a NDEF tag is read.
For BlackBerry 10, you must configure the type of tags your application will read with an invoke-target in config.xml.
On Android registered mimeTypeListeners takes precedence over this more generic NDEF listener.
On iOS you must call beginNDEFSession before scanning a NDEF tag.
- Android
- iOS
Removes the previously registered event listener for NDEF tags added via nfc.addNdefListener
.
nfc.removeNdefListener(callback, [onSuccess], [onFailure]);
Removing listeners is not recommended. Instead, consider that your callback can ignore messages you no longer need.
- callback: The previously registered callback.
- onSuccess: (Optional) The callback that is called when the listener is successfully removed.
- onFailure: (Optional) The callback that is called if there was an error during removal.
- Android
- iOS
Registers an event listener for NFC tap
nfc.addTapDeviceListener([onSuccess], [onFailure]);
Related preference:
-
boolean
EnableEncryptionWithNFC true to enable encryption when connecting to a new Tap. -
boolean
EnableNFCPairing true to enable NFC pairing when connecting to a new Tap -
boolean
EnableNFCTapDeviceDiscovery true to enable NFC Tap discovery in the native part of the plugin. -
string
NFCTapDeviceMimeType app mime type. Eg:application/com.iotize.apps.tapmanager
-
string
NFCParingDoneToastMessage toast messsage displayed when NFC pairing has been done. Give an empty string to disable this message.
- Android
Registers an event listener for NDEF tags matching a specified MIME type.
nfc.addMimeTypeListener(mimeType, callback, [onSuccess], [onFailure]);
- mimeType: The MIME type to filter for messages.
- callback: The callback that is called when an NDEF tag matching the MIME type is read.
- onSuccess: (Optional) The callback that is called when the listener is added.
- onFailure: (Optional) The callback that is called if there was an error.
Function nfc.addMimeTypeListener
registers the callback for ndef-mime events.
A ndef-mime event occurs when a Ndef.TNF_MIME_MEDIA
tag is read and matches the specified MIME type.
This function can be called multiple times to register different MIME types. You should use the same handler for all MIME messages.
nfc.addMimeTypeListener("text/json", *onNfc*, success, failure);
nfc.addMimeTypeListener("text/demo", *onNfc*, success, failure);
On Android, MIME types for filtering should always be lower case. (See IntentFilter.addDataType())
- Android
Removes the previously registered event listener added via nfc.addMimeTypeListener
.
nfc.removeMimeTypeListener(mimeType, callback, [onSuccess], [onFailure]);
Removing listeners is not recommended. Instead, consider that your callback can ignore messages you no longer need.
- mimeType: The MIME type to filter for messages.
- callback: The previously registered callback.
- onSuccess: (Optional) The callback that is called when the listener is successfully removed.
- onFailure: (Optional) The callback that is called if there was an error during removal.
- Android
Show the NFC settings on the device.
nfc.showSettings(success, failure);
Function showSettings
opens the NFC settings for the operating system.
- success: Success callback function [optional]
- failure: Error callback function, invoked when error occurs. [optional]
nfc.showSettings();
- Android
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.

iOS requires you to begin a session before scanning a NFC tag.
nfc.beginNDEFSession(success, failure);
Function beginNDEFSession
starts the NFCNDEFReaderSession allowing iOS to scan NFC tags.
If the session is closed by the user, it will trigger the Error callback (if it exists)
- success: Success callback function called when the session begins [optional]
- failure: Error callback function, invoked when error occurs. [optional]
nfc.beginNDEFSession();
- iOS
Invalidate the NFC NDEF session.
nfc.invalidateSession(success, failure);
Function invalidateSession
stops the NFCNDEFReaderSession returning control to your app.
- success: Success callback function called when the session in invalidated [optional]
- failure: Error callback function, invoked when error occurs. [optional]
nfc.invalidateSession();

This plugin is built to communicate with IoTize tags. See the original plugin if you need a more complete use of the NFC
Connect to the tag and enable I/O operations to the tag from this TagTechnology object.
//Android
nfc.connect(tech);
nfc.connect(tech, timeout);
//iOS
nfc.connect()
Function connect
enables I/O operations to the tag from this TagTechnology object. nfc.connect
should be called after receiving a nfcEvent from the addNdefListener
. Only one TagTechnology object can be connected to a Tag at a time.
See Android's TagTechnology.connect() for more info.
On iOS, connect
starts a NFC Session, and is resolved when the device is connected to a Tag.
- 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
- iOS 13 (beta)
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));

- iOS 13 (beta)
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
ndef
object 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
- ndef-mime
- ndef
The tag contents are platform dependent.
id
and techTypes
may be included when scanning a tag on Android.
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: {
"isWritable": true,
"id": [4, 96, 117, 74, -17, 34, -128],
"techTypes": ["android.nfc.tech.IsoDep", "android.nfc.tech.NfcA", "android.nfc.tech.Ndef"],
"type": "NFC Forum Type 4",
"canMakeReadOnly": false,
"maxSize": 2046,
"ndefMessage": [{
"id": [],
"type": [116, 101, 120, 116, 47, 112, 103],
"payload": [72, 101, 108, 108, 111, 32, 80, 104, 111, 110, 101, 71, 97, 112],
"tnf": 2
}]
}
}
{
type: 'ndef',
tag: {
"ndefMessage": [{
"tnf": 2,
"type": [116, 101, 120, 116, 47, 112, 103],
"id": [],
"payload": [72, 101, 108, 108, 111, 32, 80, 104, 111, 110, 101, 71, 97, 112]
}]
}
}
The raw contents of the scanned tags are written to the log before the event is fired. Use adb logcat
on Android
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.
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.
On iOS, events are fired as NDEF ones. If the application has been launched with a NFC Tag, the scanned NDEF will be fired as soon as the addNdefListener has been called
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.
See the Android documentation for more information about filtering for NFC intents.
With the proper configuration, it is now possible to launch a phoneGap / cordova app by reading a NFC NDEF Tag.
When a tag is detected, a notification appears and asks you to open the linked app. It then opens the app (if it is not open yet) and gives the NDEFMessage delivered by the tag.
You don't have to start a session anymore (cf iOS notes), but you need to accept the notification in order to retrieve the tag's content.
This feature is available on iPhone XR / XS / XS Max. earlier devices do not support background tag reading.
You will need to turn on Associated Domains and Near Field Communication Tag Reading capabilities in your Xcode project, support universal links and add the website linked to the app as an Associated Domain with the following scheme:
applinks:www.example.com
Tag delivery is then handled by the plugin.
Check out the official documentation for more precise informations.
