Every day billions of banknotes and coins change hands, enabling transactions and contributing to economic growth. Banknotes and coins are a collective good. They are issued by central banks or monetary authorities, distributed by banks and spent by individuals. Because it is a common good, the evolution of cash is shaped collectively. Central banks may decide on the design and the denomination mix; commercial banks facilitate the distribution by deploying ATMs and branches; retailers facilitate its acceptance; but it is ultimately the consumer who drives demand. The purpose of this website is to provide an unbiased source of information and a forum for debate on the future of cash. This website was launched in April 2016. The original content is based on the white paper "Cash Essentials - Beyond Payments".
