We handle banknotes all the time, yet we seldom pause to think about what lies behind – and within – them. In this episode we discover how today’s banknotes are designed, through a process that combines art, technology, science and even psychology to create something as familiar as it is indispensable. Because a banknote is not defined by its face value alone: it also stands for trust, identity, and much more besides.
