Base Claim:
1. A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality affecting parameter, said barcoded indicator comprising: at least a first barcode including at least a first set of initially uncolored, colorable areas including at least one initially uncolored colorable area, positioned at locations between bars of said first barcode when said first barcode is in a first barcode readable state prior to exceedance of said at least one threshold; at least a second barcode including at least a second set of initially uncolored, colorable areas including at least one initially uncolored colorable area, positioned at locations of bars of said second barcode which appear only when said second barcode is in a second barcode readable state following exceedance of said at least one threshold, a coloring agent located at a first location on said indicator; and a coloring agent pathway operative to allow said coloring agent to move from said first location to said first and second sets of colorable areas for coloring thereof, said at least a second barcode being in a second barcode unreadable state prior to exceedance of said at least one threshold wherein as the result of said at least a second set being uncolored, more than a single narrow barcode bar is missing from said at least a second barcode, and upon exceedance of said at least one threshold said at least a first barcode becoming unreadable as the result of coloring of at least a portion of at least one colorable area forming part of said at least a first set of colorable areas and generally simultaneously said at least a second barcode becoming readable as the result of coloring of said at least a second set of colorable areas.
