RFID READER CONTROL INTEGRATED WITH SMART GARMENT

1 . A method of retrieving a specific RFID tagged item from a group of RFID tagged items comprising the steps of scanning the group with a RFID reader carried by an operator, when the reader finds the tag of the specific item to be retrieved in its range, causing processing associated with the reader to record the identity of the tags of the group within the range of the reader and signaling the operator of such finding, allowing the operator to retrieve the specific item from the group and move away from the group with the specific item, the processing associated with the reader being programmed to detect changes in the tags being read from those recorded when the specific item tag was found and interpreting the detected tag changes as movement of the operator associated with retrieval of the specific item.

2 . A method as set forth in claim 1 , wherein the processing associated with the reader is programmed to verify with the reader that the operator is carrying the correct item after movement is interpreted.

3 . A portable RFID tag reading system to be carried by an operator and including a reader with associated processing, the processing being programmed to record as a set the identity of all of the RFID tags in the range of the reader when the reader finds a specific RFID tag and to detect movement of the operator after the specific RFID tag is found by recognizing a change in RFID tags seen by the reader from the recorded set.

4 . The system of claim 3 , arranged on a garment worn by the operator.

5 . The system of claim 3 , wherein the processing is programmed to verify when operator movement is detected that the operator is carrying the item bearing the specific RFID tag.

6 . The system of claim 3 , wherein said associated processing is provided by a small board computer.
