ABSTRACT OF THE DISCLOSURE A system for processing articles selected for purchase and bearing distinct identification codes comprises, in one version: (a) a code reader for generating an output signal indicative of such article identification code; (b) a conveyor for receipt and transport of such article; (c) an entrance sentry for defining an inlet to a secured zone extending along a portion of the conveyor; (d) a sensor for sensing a measurable characteristic of an article and generating an output signal indicative thereof; and (d) a controller for selective movement of the conveyor in respective article acceptance and article rejection senses. The controller is operable in several respects, namely, for storage, for each of a plurality of such articles, of a signal indicative of a predetermined value of the measurable article characteristic correlated with such article identification code, for response to the code reader output signal for comparison of such stored signal with the output signal of the sensor, and for operation of the conveyor selectively in response to the results of such comparison. In other versions, the system looks to other measures for article processing, including a second reading of article identification code in the secured zone and comparison thereof with the code read in (a) above, comparison of measured weight with stored weight and electronic article surveillance (EAS) testing in conjunction with stored EAS information regarding marker-tagged articles. In another version, the system uses components thereof to compile its stored information.
