One outcome of the ongoing struggle against counterfeit banknotes is that central banks worldwide periodically introduce new banknotes. These are ideally designed with the best existing technology, while keeping the future in mind, to keep bad actors at bay for the life cycle of that series. This means incorporating the most cutting-edge security features on the banknote, including those that are visual, haptic, and machine-readable.
An ever-present reality of the cash cycle is that the same technology that powers advances in currency technology is also available to counterfeiters. As the Bureau of Engraving and Printing (BEP) in the United States pointed out, “Notes must be resistant to increasingly sophisticated counterfeit attacks – security is the primary purpose of redesign.”1
