ABSTRACT:
A badge reader logic system is provided for receiving binary coded information read from a badge, card or other recording medium having data encoded thereon by means of bistable magnetic wire patterns, and reformatting such binary coded information into a two-dimensional data matrix row and column format for processing by a local controller. The binary coded information further is interrogated in time relation with logic signals received from sensors placed along an insertion path of the badge into the badge reader to detect unauthorized badges, incorrect badge orientations and other error conditions.
