Most secure banknote

The Swiss franc banknotes are considered to be the most secure currency in the world, particularly amongst the Organisation for Economic Co-operation and Development (OECD) member states' national currencies. The 1,000 Swiss franc note has 14 security features with the aim of deterring counterfeiting: watermark, intaglio printing (a way of printing numerals, words and patterns), micro lettering, fluorescent ink, see-through register (a pattern printed simultaneously on both sides of the note), fluorescent security fibre, latent image, braille, optically variable ink (OVI), windowed thread, optical variable device (OVD), transparency ink, microperf (microscopic perforations) and metallic coating.
