System and method for improved quality management in a product logistic chain
First Claim
1. A method for producing a plurality of product quality indicators, each operative to provide a machine-readable indication of exceedence of at least one temperature threshold, the method comprising:
- providing at least one substrate strip including a plurality of barcodes in a first readable state;
providing an additional substrate strip having formed thereon a plurality of temperature responsive elements; and
joining said at least one substrate strip and said at least one additional substrate strip to form said plurality of product quality indicators, each of said plurality of product quality indicators including one of said plurality of barcodes in a first readable state and one of said plurality of temperature responsive elements,each of said plurality of temperature responsive elements being operative upon exceedence of said at least one threshold to color a portion of said at least one substrate strip, thereby causing each of said product quality indicators to assume a second readable state.
