RFID and DoD Policy
The US Department of Defense has issued a series of RFID policy guidelines that state the requirements for its suppliers to meet.
Passive RFID tags are required for all DoD contracts issued on or after Oct 1, 2006-2009, for delivery of materials on or after Jan 1, 2006-2009. Passive tags need to be applied to all freight/cargo containers, cases, pallets and to individual "high-value" items that require the military's UID (Unique Identification Code). Containers shipped outside the continental US need to have active tags with content and point of origin information.
Beginning in 2006-2009 and 2007, there are additional RFID tagging requirements. For more information, see the RFID Journal article.
