1. A method for providing quality management for products, the method comprising:
employing a multiplicity of barcoded quality indicators each operative to provide a machine-readable indication of exceedance of at least a first threshold and a second threshold by at least one product quality affecting parameter, each of said indicators comprising:
a first barcode, said first barcode initially being in a first barcode machine-readable state prior to exceedance of said first threshold, said first barcode being operative to assume a first barcode first non-machine-readable state and at least one first barcode second non-machine-readable state following exceedance of said first threshold;
a second barcode, said second barcode initially being in a second barcode first non-machine-readable state prior to exceedance of said first threshold, said second barcode being operative to assume a second barcode machine-readable state upon exceedance of said first threshold, said second barcode being operative to assume at least one second barcode second non-machine-readable state following exceedance of said second threshold; and
at least one third barcode, said at least one third barcode initially being in a third barcode first non-machine-readable state, said at least one third barcode being operative to assume at least one third barcode second non-machine-readable state upon exceedance of said first threshold, said third barcode being operative to assume a third barcode machine-readable state upon exceedance of said second threshold; and
reading said barcoded quality indicators to provide output indications;
receiving said output indications; and
interpreting said output indication to provide product quality status outputs.
