What is RFID?

Radio-frequency identification is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

When both IUID and RFID requirements are listed on a contract, the relationship between the two is actually quite simple. Both standards are followed which means that parts requiring UID’s are labeled or marked with the appropriate UID and containers and shipping containers that are packed with IUID labeled parts are tagged with RFID tags. This creates a parent/child relationship between RFID tags and UID labels/marks. The parent/child relationship is “documented” in the WAWF submission. This documented relationship allows the receiving DoD depot to read the RFID tag on a container and know what parts are contained in the container. This provides for a perfect audit trail of both UID and RFID labeled parts and shipping containers
