Passive UHF RFID Tag Data Structure Requirements – DoD RECEIVING POINTS SHIPPING ITEMS DOWN THE SUPPLY CHAIN TO DoD CUSTOMERS

NOTE: DoD initial implementations will use currently available 64-bit tags but should transition to 96-bit tags as soon as practicable, but no later than January 1, 2005.

Class 1 – 96 bit tags

DoD 96-Bit Data Construct - 96 bits total user memory on tag

Fields:

• Header – specifies that the tag data is encoded as a DoD 96-bit tag construct, use binary number 1100 1111
• Filter – identifies a pallet, case, or UID item associated with tag, represented in binary number format using the following values:
  • 0000 = pallet
  • 0001 = case
  • 0010 = UID item
  • all other combinations = reserved for future use
• DODAAC/CAGE – identifies the supplier, insures uniqueness of serial number across all suppliers, represented in ASCII format
• Serial Number – uniquely identifies up to 2³⁶ = 68,719,476,736 tagged items, represented in binary number format
  
  

Sample binary encoding of the fields of a 96 bit Class 1 tag on a case shipped from DoD internal supply node

Complete content string of the above encoded sample tag is as follows:

NOTES:

1. Specific tag orientation and location, as well as physical mounting requirements will be addressed in MIL-STD 129.

2. Advance Ship Notices (ASNs) will be required as specified in contracts in accordance with the appropriate DFARS Rule/clause.

3. It is the intent of the Department to incorporate all RFID tag formats and usage standards into a DoD RFID manual.
