VARIABLY SPACED MULTI-POINT RFID TAG READER SYSTEMS AND METHODS

摘要

Systems and methods for determining a time of a passing at a reference line of an RFID tag traveling along a route and a time of lapsing of the tracked RFID tag on the route, the system have a plurality of spaced apart tag reader systems for wirelessly obtaining tag reads, wherein at least one of the tag reader systems is space apart from the reference line. The timing system receives a plurality of tag reads and determines the time of passing of the RFID at the reference ID line responsive to the plurality of received tag read messages received from the plurality of tag reader systems.
