Title
(EN) THERMOCHROMIC BAR CODE
(FR) CODE BARRES DE TYPE THERMOCHROMIQUE
Abstract
(EN) A bar code (10) incorporating thermochromic materials in selected modules (20) such that its code changes with temperature. Below a specified temperature, the bar code (10) displays the code as in Fig 3. Above this temperature, the bar code (10) shows a new code as in Fig. 2. The bar code (10) is printed with conventional printing equipment (not shown) onto conventional printing media, and is scanned with conventional bar code scanning equipment (not shown).
(FR) L'invention concerne un code barres (10) renfermant des matériaux thermochromiques dans différents modules (20), de sorte que le code varie en fonction de la température. En dessous d'une température spécifiée, le code barres (10) présente le code correspondant à la figure 3. Au delà de cette température, ledit code (10) présente une nouvelle valeur, comme indiqué sur la figure 2. Le code barres (10) est imprimé sur des supports d'impression conventionnels au moyen de matériel d'impression classique (non représenté), et sa lecture est effectuée par le biais d'équipement de lecture de code barres classique (non représenté).
