Patent ID: 7511618

Claim:
A system for tracking transported grain, the system comprising: a writer for recording data into an RFID tag, the data including at least a time when the RFID tag was handled with surrounding grain and information sufficient to determine a location of handling at the time when the RFID tag was handled with surrounding grain; a reader for retrieving said recorded data from the RFID tag; a radio-frequency identification (RFID) tag dimensioned to have a size approximating surrounding grain, said tag comprising a memory and an RF communication channel, wherein said writer records the data in the memory, and wherein said reader retrieves the recorded data from the memory; a remover for removing said RFID tag from surrounding grain; wherein said remover comprises: a container for holding RFID tags; a magnet for magnetically attracting the RFID tags; and a moving surface for moving said magnetically attracted RFID tags towards said container, said moving surface being disposed between said magnet and the surrounding grain including the RFID tags; said moving surface moving said magnetically attracted RFID tags to a location wherein the RFID tags are sufficiently displaced from a force of said magnet and is permitted to freely fall into said container.
