How do banknote detector pens work? The practise of counterfeiting money is as old as the printing of money itself. There have been numerous advances in anti-counterfeit technology; from 'raised prints' and 'see-through registers', to the rumoured introduction of technologies to help banknote detectors such as microchips inside the fabric of notes. Yet the counterfeiters still manage to succeed in mass-producing notes that pass though the publics'hands un-noticed. One of the simplest ways to identify counterfeits is to test the 'paper' fabric itself. As the supply of genuine banknote paper is restricted and controlled by the authorities, the type of paper used by the counterfeiters can differ greatly.
