With process and production improvements modern banknote substrates are made from sustainable fiber materials that provide extended durability and are environmentally friendly. These substrates are equipped with embedded security features, ensuring that the authenticity of cash is never compromised. Our overall goal is to provide a blueprint for sustainable currency solutions that meet the essential requirements of durability and security from within. With this approach we invite the industry to take similar measures together towards reducing the environmental impact and contribute to a more sustainable cash cycle.
