nfcDisabled The NFC sensor is disabled.

Scan in progress.
nfcUnavailable The device is not equipped with an NFC sensor or this one is not available.

Remarks

Special cases

The NFC functions are only available in read-only mode.
The activation status of the NFC sensor cannot be modified programmatically.
If the NFC sensor is not enabled, the user has the ability to enable it via the window for configuring the wireless communications by using the following code in a procedure in native Java code:
getCurrentActivity().startActivity(new android.content.Intent(
android.provider.Settings.ACTION_WIRELESS_SETTINGS));
The NFCStatus function cannot be used in either the simulator or the emulator: the function will return the constant nfcUnavailable.
NFCStatus is available only for devices running Android 2.3.3 or later (API level 10).
A fatal error occurs if the function is used with an earlier system version.
To determine the version of Android the application is running on, use SysAndroidVersion.
NFCStatus is only available on iPhones from iPhone 8 onwards.
