Yes Ginger, there is an app for that. A couple weeks ago Ginger Rapsus asked if there were any smartphone apps designed to detect counterfeit currency. I hadn't heard of any, but this week I can across this announcement from a company in Germany. The app interacts with a specific security printing feature. It's not a general app, but a step in that direction.
German smartcard and security printing group Giesecke & Devrient has developed a security feature called MAGnite that allows mobile phone users to verify banknotes authenticity. The system uses interaction between special colour pigments and magnets such as those used in mobile phone speakers. The colour pigments align along the magnetic field lines when the note is placed over a magnet and make the feature visible through a high-contrast change of the image on the note. MAGnite works with other magnets, such as those in store checkout theft-prevention systems. The head of G&D's banknote printing division, Bernd Keummerle, said that due to its ease of use and easily recognised optical effect, MAGnite is a sound alternative to watermarks and security threads for the general public.
