What is difference btw Biztalk Server 2006 and Biztalk Server RFID

What is difference btw Biztalk Server 2006 and Biztalk Server RFID? There is documentation available for Biztalk Server RFID and Nav integration. Is there any documentation for Biztalk Server 2006 and Nav integration?

Biztalk Server RFID is a feature of Biztalk Server 2006 R2. If you are using Biztalk Server RFID then you are using Biztalk Server 2006 R2.

Thanks…
