'NumberingSystemIndentifier'

What is the 'NumberingSystemIndentifier' of a TagReadEvent and why the 'tagReadEvent.GetNumberingSystemIndentifier()) method returns null byte array when using the 'Acme' provider and device?

NSI (Numbering System Identifier) is a part of the Protocol Control bits in a tag memory map for Gen2 tags.

It supposed to tell you which standard the tag belongs to and contain an EPCglobal Header (defined in the EPC Tag Data Standards) or an AFI (defined in ISO/IEC 15961.)

In most cases it is not used and you can disregard it as the Acme (Contoso) provider and many other real providers and devices.

Hope this helps,

For more detail look at the EPCGlobal Tag Data Standard at

http://www.epcglobalinc.org/standards/tds/tds_1_3-standard-20060308.pdf

In case the link gets broken or updated in future, click the tag data link on http://www.epcglobalinc.org/standards. Today it was a blue box at the bottom of the standards overview architecture.
