Midwest Book Review

A Cash-Free Society provides a simple and clear explanation of the movement toward new forms of financial transactions. Olsen again demonstrates his ability to tell a story that everyone can understand. He manages to stay true to the complexity of the underlying technology while helping the reader to see the transition in easy to understand terms. The book is worth reading just for his brief introduction to computer applications and his story-telling reaches new heights with 'Uncle Joe’s Island.'

We are living in a digital world. Digital currency’s supporting infrastructure is inevitably taking over cash payments. Moving towards a cash-free society may be challenging. In this excellent book, Kai Olsen wisely describes technologies, processes, and implications of this movement, providing the reader with a complete picture of this crucial topic for our future society.

The cash-free society is arriving without much notice, and Olsen highlights important implications, offering a forward looking discussion of this significant transition.

Petter E. Bjørstad, Professor, University of Bergen

Olsen outlines alternatives for using cash and explains complications associated with those alternatives. He describes the history of gold, silver, coins, banknotes, checks, and credit cards. Barcodes, transaction fees, digital credit, and debit cards, bitcoin, and blockchains complicate the transition to the digital world. The best part of the book is the summary of the strengths and weaknesses of the digital economy. Recommended.
