    摘要: A liquid crystal polymer marking is obtainable by a process that comprises applying a first chiral liquid crystal precursor composition onto a substrate, heating the composition to bring same to a first chiral liquid crystal state, applying to at least one area of the first composition a second chiral liquid crystal precursor composition, heating the at least one area to bring same to a second chiral liquid crystal state, and subsequently curing and/or polymerizing the resultant product. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

    摘要: An item according to the invention comprises at least two data storage elements such as e.g. an RFID transponder 2 and a barcode 5, wherein the latter is non-visible for the unaided human eye and comprises coded information. The invention allows for a backup of information between the two data storage elements, in order to prevent inadvertent or malicious data loss. Further aspects of the invention are related to the interdependent or the cooperative use of both storage elements in the framework of a product security tracking and tracing scheme.
