Remarks

Provides access to NFC-A (ISO 14443-3A) properties and I/O operations on a Tag.

Acquire a NfcA object using #get.

The primary NFC-A I/O operation is #transceive. Applications must implement their own protocol stack on top of #transceive.

<p class="note"><strong>Note:</strong> Methods that perform I/O operations require the android.Manifest.permission#NFC permission.
