Traditionally, the evaluation of the perception of the banknotes is based on explicit responses obtained through questionnaires and interviews. The implicit measures refer to methods and techniques capable of capturing people’s unconscious mental processes. Neuroscience has shown that in the majority of brain processes that regulate emotions, attitudes, behaviours and decisions does not intervene human consciousness, that is: visual interest, attention to certain areas, emotions, motivation, mental load to understand the design and level of stimulation when interacting with a banknote.

The Banco de España and the LENI Institute of Universidad Politécnica de Valencia have developed Neurocash: a new methodology based on the application of neuroscience and artificial intelligence, which provides an objective and scientific understanding of the public’s real interests and perception of cash and security features.

Neurocash will bring to cash professionals countless advantages in order to develop the best product for a world where it should evolve and coexist with other means of payment:

· Criterion for making decisions about which banknote designs and security features have the most suitable configuration,

· Measurement of the resilience of banknotes to be counterfeited,

· Analysis of the perception of manufacturing defects,

· Virtualization of neuro-designed prototypes and,

· Evaluation of effectiveness of the cash communication campaigns.
