发明名称 DATA CARRIER PRODUCTION PROCESS
摘要 The invention relates to different methods for distortion-free production of data carriers having at least in partial areas a transparent plastic layer with a surface structure in the form of a lens structure. The surface structure can be produced by cutting methods or embossed by applying heat and pressure. Alternatively the surface structure can be produced as a separate element which is connected after its production with the data carrier.
