Abstract

In one aspect, the invention encompasses a method for electronic tracking of units originating from a common source which comprises a plurality of units physically joined with one another. A first transponder is physically associated with the common source, and the source is split to separate it into three or more of the units. A second transponder is physically associated with one of the three or more units, and the second transponder sends a code. The code of the second transponder is electrically associated with an identifier of the common source. In a particular aspect, the common source is an animal carcass.A batch comprises separate units of objects that are physically joined together. RFID tags are attached to each of the units and to the batch. The codes stored in the RFID tags are electrically associated with one another in a database.
