Abstract
A badge reading system is provided which includes a badge having embedded therein bistable magnetic wires arranged in BCD encoded logic patterns, and a badge reader for reading the bistable magnetic wire patterns to form an information stream. As the badge is inserted within the badge reader housing, the movement of the badge is sensed at initial, intermediate and full insertion points along the insertion path. A logic control system of the badge reader operates in concert with the sensors and a bistable magnetic wire detector to protect against data errors which may occur because of incorrect badge orientations and insertions, and counterfeit badges.
