Abstract

A system and method are useful for tracking two or more objects moving by separate transport paths to a destination and associating the objects at the destination. Object and check smart tags (200-N, 200-RX) are associated respectively with each object (280, 290) to be tracked and with an associated check object (RX). Each smart tag includes at least an electronic memory from which information may be transmitted and/or into which information may be stored. Smart tag control units (reader and/or writer) (42) and antenna arrays (44) along the transport path (40) communicate with the smart tags and/or communicate directly or indirectly with one or more processors that process the information. Object and check smart tags are read and compared for matching the object and check object at the destination.
