Abstract
A data reading system, and associated methods of operation, for locating and tracking a position of tagged items on a conveyor system. The system includes a data reader and a conveyor system operable to transport the tagged items through a read region of the data reader. A processor, in operative communication with the data reader, obtains data from an item tag being passed through the read region at a first time, at a second time, at a subsequent third time, and so forth. Based on the readings, the processor estimates an initial position of each item tag and determines an order at which each item reaches a reference position on the conveyor system.
