NFC stands for Near Field Communication, this is a technology that has emerged as a game changer in mobile application development, providing seamless interaction between devices with just a touch. Among its many capabilities, NFC tag reading stands out as a powerful feature that allows developers to create innovative and user-friendly experiences in their Android apps. In this article, we will explore NFC in detail while also understanding how to read NFC tags in Android Studio

What is NFC?

NFC is a wireless technology that allows data to be transferred between devices over very close distances, usually just a few centimeters. This technology works on the principle of creating an electromagnetic field and communicating through it to transmit data between devices. NFC is commonly used for a variety of purposes, including mobile payments, data exchange, device connectivity, and task automation. In the mobile industry, NFC has become an important technology, especially in creating utility applications and services such as mobile payments, smart cards, and device connectivity. The strength of NFC lies in its convenience, high security, and compatibility with many different types of devices.

The convenience that NFC brings

1. Quick and easy connection:

NFC allows connection between devices simply by bringing them close together without needing to set up or search for devices in Bluetooth or Wi-Fi lists. This reduces the time and complicated steps required to connect, providing a fast and convenient experience for users. We can easily see it through Sony devices, just turn on NFC on the Sony speaker and the Sony phone, and then put them close to each other and they will connect immediately.

2. Mobile payment:

NFC has changed the way payments are made by allowing users to make financial transactions simply by touching or placing their mobile phone near an NFC reader, such as a payment terminal or machine. POS. This creates a quick, convenient, and secure payment process. The most prominent include Google Pay, Samsung Pay, and Apple Pay

3. File and data transfer:

NFC provides a convenient means of transferring files and data between devices without the need for an internet connection. Users can share photos, videos, contacts, or other files simply by touching their phone to another device.

4. Connecting IoT devices (Internet of Things):

NFC provides a simple way to connect IoT devices to each other or to the user's mobile phone. This may include configuring and connecting to devices such as lights, door locks, or other smart control devices.

5. Bluetooth and Wi-Fi connection:

NFC can also be used to initiate a Bluetooth or Wi-Fi connection between devices. Instead of having to search and connect manually, NFC can start this process automatically, reducing inconvenience for users.

How to use NFC in the Android Studio Project

Here's a basic guide to setting up the NFC tag reading in the Android Studio project:

1. Check NFC availability:
Before integrating NFC into your app, ensure that the device is capable of reading NFC and that NFC is enabled. You can do this programmatically using the NfcAdapter class.

2. Add NFC permission and declare NFC feature to Manifest:
Open your app's AndroidManifest.xml file and add the necessary permissions:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android=""  xmlns:tools="">

              <uses-permission android:name="android.permission.NFC" />
              <uses-feature android:name="android.hardware.nfc" android:required="true" />


3. Define NFC Intent Filter:
Specify intent filters in your manifest to indicate which activities in your app should handle NFC-related actions, such as tag detection, reading, or writing.

For example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="" xmlns:tools="">
    <uses-permission android:name="android.permission.NFC" />
                    <action android:name="android.nfc.action.NDEF_DISCOVERED" />
                    <category android:name="android.intent.category.DEFAULT" />

4. Handle Intent in Activity:
In your activity's onCreate() method, handle the NFC intent:

protected void onCreate(Bundle savedInstanceState) {

        if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(getIntent().getAction())) {
                  // Handle the NFC intent here

private void handleNfcIntent(Intent intent) {
        // Extract the NFC tag information from the intent
        Parcelable[] rawMessages = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
        if (rawMessages != null) {
                NdefMessage[] messages = new NdefMessage[rawMessages.length];
                for (int i = 0; i < rawMessages.length; i++) {
                       messages[i] = (NdefMessage) rawMessages[I];
                // Process the NDEF messages
               // ...


In conclusion, NFC tag reading offers a myriad of benefits for Android app developers, ranging from seamless interaction and information retrieval to authentication and security. By leveraging NFC technology in your Android Studio projects, you can create immersive and intuitive experiences that delight users
