Abstract
Recent research using neuroscientific methods is discussed to demonstrate their potential in the field of banknote analysis research. This study seeks to highlight the importance of these methodologies and the possibilities they offer to improve authenticity and cash design. The report covers key literature from a variety of domains, including neuroscience and consumer neuroscience, to provide detailed insights into the most important measurement tools today. Their theoretical and empirical value is analysed to assess how these tools can complement traditional research methods. To date, the use of measurement tools in the cash field has been limited, which is surprising given their great potential to advance research. The results indicate that tools such as electroencephalography (EEG), eye tracking (ET), skin conductance (SCR), heart rate variability (HRV) and facial expression coding (FC) are crucial for obtaining detailed information on neural and physiological responses to visual and tactile stimuli. The report provides a comprehensive overview with insights into the value of adopting the neuroscientific approach and its complementarity with traditional research methods. It also highlights the need to integrate these methodologies to gain a more complete understanding of consumer behaviour and cash perception. This integration can not only improve the security and functionality of cash, but also foster a stronger emotional connection with users, ensuring its relevance in an ever-changing society. Future research should focus on expanding the application of cross-cultural assessments, developing cash prototypes with enhanced tactile features and exploring the interaction between vocal and tactile stimuli in banknote authentication. Finally, research should continue to investigate the inclusion of people with visual impairments in cash perception studies by implementing specific tactile features that make it easier to determine the authenticity of cash and promote inclusion and usability.
