Abstract:
1. System for systematically and automatically controlling a product, whose preservation in a distribution circuit depends on the temperature; the system comprising: a marker, affixed on the product, comprising elements, intended to be identified by the automatic processing units managing the marketing of the product, a component, fixing means for fixing the component on the product at the location of the marker; the component including at least one part comprising masking means for masking the elements of the marker without modifying them, when (i) the temperature of the product exceeds a specific temperature threshold or (ii) when the preservation conditions differ from a specific reference level, or by exceeding a specific preservation duration; whereby when the elements of the marker are masked by the masking means and the automatic processing units can no longer read the markers; wherein: the fixing means are configured to fix at least a portion of the masking means on the product so that the masking means may be removed; when the elements of the marker are masked, the removable portion of the masking means is configured to be removed by a regulatory agency to make the marker legible again; and the component further includes an irreversibly fixed part including an indicator of any changes in the preservation conditions of the product, the irreversibly fixed part including an indicator of the changes in the preservation conditions of the product; whereby, when there is a change in the preservation conditions of the product, the product affected by this change can be identified beyond dispute even if the masking means have been removed.
