Currency News October 2018: Micro-mirrors have been in use for banknote security features by Louisenthal, a subsidiary of G+D Currency Technology, for several years now. About 4 million microscopic mirrors per square centimetre are aligned and shaped in such a way that the collective impact of their reflections results in an image that moves dynamically when the banknote is tilted. It even enables 3D effects such as reliefs or the shifting and floating of objects.
