In the tester the light emitter, the reflective/transreflective element and the photodetector are arranged in the measuring slot in such a way that detection of the level of absorption and/or refraction of light passing through a graphene security element is possible and the measurement result when compared with the model provides a basis for generation of a message about the detection result, i.e. the confirmation of authenticity of a security document or information that the document is counterfeited. The tester can preferably be used in combination with a mobile device, such as a smartphone, which together form the measuring system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tester for detecting graphene security element in a security document, and the element detection method","description":"A tester is described for detecting a graphene security element in a secure document, such as a banknote, an identification card, etc. as well as a method for detection of that element.
