TRACKABLE FILES AND SYSTEMS FOR USING THE SAME

摘要

A system for tracking files at a site having a plurality of locations includes a plurality of antenna arrays and a plurality of files (130). Each of the antenna arrays generates an energizing field and is disposed at or near one of the locations. Each of the files includes a body (132) including a pair of covers (134a, 134b) and a transponder assembly (140). The transponder assembly may include a substrate (142), an antenna (144) disposed on one of the sides of the substrate, a circuit (146) coupled to the antenna and having an identifier code, and an adhesive layer (148) disposed on the other side of the substrate. The transponder assembly may be attached to one of the covers by the adhesive.
