Detailed Description

The mask the reader holds, and how it is matched.

Reading it back is the only way to see what the reader is actually addressing. A Select produces no reply from any tag (EPC Gen2 v2.1 6.3.2.12.1.1), so nothing else confirms that the reader and the caller agree on which tag is meant
