Abstract
A flexible, digital enhanced reading device (P) comprises at least one label containing encoded information, a spatially structured element placed over the label itself, defined by a material indicating predetermined temperature level and exposure time range, and comprising a material with morphological and/or structural and/or chemical and/or physical state changing properties detectable following a predetermined heat absorption; the mentioned spatially structural element is adapted to at least partially cover determined zones of said label with dimensions between 0.01% and 100% of the surface of the label itself, and comprises molecular materials and/or polymer materials and/or liquid crystals and/or mixtures of said materials in any proportion.
