28. A method of retrofitting a fixture for use in a retail store, comprising the steps of:
-
(A) providing at least one loop formed from a conductive material, the loop adapted to support retail articles;
(B) opening a gap in the loop to yield a first end and a second end of the loop;
(C) inserting an insulating member in the gap to provide structural support for the loop; and
(D) electrically connecting an RFID reader between the first end and the second end of the loop to form a circuit by the loop and the RFID reader wherein the loop provides an antenna function for the RFID reader. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
