How to Determine if Android Device has NFC Feature

public static final String FEATURE_NFC was added in API level 9
Feature for getSystemAvailableFeatures() and hasSystemFeature(String).
The device can communicate using Near-Field Communications (NFC).
Constant Value: "android.hardware.nfc"
Here are some examples of  Android Phones with NFC.


1. Get a PackageManager Instance named myPackageManager.

2. Create a Boolean Variable named bolNFCSupported. 

3. Set the Minimum and Target SDK version  to 9 or greater. 

4. In the onCreate method, add the below code. This will return the NFC ability to a boolean named bolNFCSupported. It will then display a toast displaying the NFC ability of the device to the user.

bolNFCSupported = myPackageManager.hasSystemFeature(PackageManager.FEATURE_NFC);
if (bolNFCSupported) {
Toast.makeText(this, "Device has NFC capability. Yay!", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "No NFC capability!", Toast.LENGTH_LONG).show();
}

5. Compile and run!
