A BAAD™ Way to Assess Substrate Durability

UnderCurrency was established in 2019 as a technical consultancy service. We are based in Mexico and specialise in methodologies, solutions and systems for evaluating and enhancing the security, functionality and durability of secure documents and banknotes.

Our team of scientists work with central banks seeking innovative strategies to increase the lifespan of banknotes. UnderCurrency has developed an approach to predict the performance of different substrates and security features, substrate being the most influential factor in determining banknote performance in circulation.

A print trial followed by a controlled circulation trial is a traditional approach to evaluating circulation performance but is time consuming, expensive, and carries risk. This can be mitigated through laboratory testing using accelerated ageing processes designed to simulate circulation conditions.
