I had a question from a partner about showing the RFID integration AX2009 has with Microsoft BizTalk RFID Server. This is setup on the AX-SRV-03 which is the companion VM that we ship. See my note posted here on setting up the AX-SRV-03.
You will need to be familiar with the SCM functionality in AX to be able to show this and have some knowledge of the RFID Server Device simulator. http://msdn.microsoft.com/en-us/library/dd298739.aspx . This is all setup on the VM.
