Experience design that works – turning central bank visions into currency people trust
Mr. Mittelstaedt, the line “Experience design that works” sounds intriguing. What does it mean at G+D?
Marc Mittelstaedt: For us, it’s not only an aesthetic statement , it has a very technical meaning, too. And it goes further: “Design is only WOW if it WORKS” – in cash centers, in people’s wallets, and across the entire cash cycle. If a note looks impressive but causes problems in production or wears out quickly in circulation, it doesn’t serve its purpose.
At the same time, banknotes are far more than a means of payment. They are part of everyday life, they carry history and identity, and they connect people with their currency. They have to protect and connect. “Experience design that works” therefore covers two dimensions: the experience of everyone who touches a note, and the experience we bring as a partner into every project.
How do central banks experience this approach in day-to-day collaboration with you?
We like to talk about a shared positive experience, because the best banknotes are always co-creations. Customers bring their objectives, motifs, sometimes their own designers or preferred components. Meanwhile, demands for counterfeit protection, sustainability, and compliance continue to rise, requiring innovative collaboration models. Our role is to turn all of this into a solution that works – technically, securely, and economically.
Kazakhstan is a great example. Together with the National Bank we developed the “Saka Style” series, working with a designer involved by the customer, clear cultural references, and specific feature requirements. Our task was to translate that vision into something that performs in real life: the right substrates, integrated security threads and patches, machine processing, and coherent color schemes. The result was a series that makes tradition, culture, and confidence visible. And when the 10,000-tenge note was awarded “Best New Banknote Asia” in 2024, that was first and foremost an award for the customer’s currency, while of course also affirming our work behind it.
