2.4.7 DoD Identity Type
The DoD Construct identi?¬?er is de?¬?ned by the United States Department of Defense. This
tag data construct may be used to encode 96 bit Class 1 tags for shipping goods to the
United States Department of Defense by a supplier who has already been assigned a CAGE
477 (Commercial and Government Entity) code. At the time of this writing, the details
of what information to encode into these ?¬?elds is explained in a document titled
United States Department of Defense Supplier??™s Passive RFID Information Guide that can be
obtained at the United States Department of Defense Web site (http:==www.dodr?¬?d.
org=supplierguide.htm).
2.4.8 Detailed Description of Tag Data Standards
The speci?¬?cation provides a number of tables de?¬?ning each of the ?¬?elds in making up an
EPC code, such as all of the headers (256 available) that are currently de?¬?ned, detailed
structure of C1G2 EPC Memory Bank, such as CRC16, Protocol Control (PC) bits (16 in
total), Numbering System Identi?¬?er (NSI), and reserved bits.
Then for each type, ?¬?ne details of how each of the ?¬?elds are further split, for example the
SGTIN-96 consists of 8 bits for the header, 3 bits for the ?¬?lter value, 3 bits for the partition
value, 20??“40 bits for the company pre?¬?x, 24??“4 bits for the item reference, and 38 bits for the
serial number.
