A system for tracking elements employing fixed tags that are permanently
attached to elements. The tags include radio-frequency (RF) communication
units that are adapted for wireless communication with RF communicators.
The RF tags are permanently affixed to elements as part of the
manufacturing of products such as cell phones, PDA's, computers, routers
and other electronic equipment. The RF tags are installed during
manufacturing in a manner that resists tampering and interference. The RF
tags are installed with mechanical barriers to access and are hidden from
view in non-user accessible locations.
