Say good-bye to your beloved Benjamins, because the world is going cashless. So says David Wolman, and in The End of Money, he explores the drastic implications. How is it happening? What's at stake? Why does it matter?

Each chapter of this timely and fascinating audiobook focuses on a specific aspect of the coming cashlessness. Its cast of compelling characters includes an end-times fundamentalist who views the growing obsolescence of cash as a sign of the coming rapture; an Icelandic artist whose claim to fame illustrates the complicated relationship between cash and nationalism; an American libertarian and coin-maker convicted on federal charges for the distribution of "Liberty" coins and Ron Paul dollars; and an Indian software engineer (self-billed as "the assassin of cash") whose firm is enabling digital payment methods that are lifting the living standards of thousands of poor New Dehli residents via their cell phones. Raising the stakes with a personal experiment, Wolman goes (almost) a full year without using cash at all. All told, The End of Money offers everything there is to love about popular nonfiction, rendering a complex subject entertaining and easily approachable for a wide audience while proving the ultimate adventurousness inherent in a curiosity about the workings of the world.
