Remarks
Provides access to NFC-B (ISO 14443-3B) properties and I/O operations on a Tag.
Acquire a NfcB object using #get.
The primary NFC-B 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.
