For ages, money has been represented by little metal disks and rectangular slips of paper. Yet the usefulness of physical money- to say nothing of its value- is coming under fire as never before. Intrigued by the distinct possibility that cash will soon disappear, author and Wired contributing editor David Wolman sets out to investigate the future of money, and how it will affect your wallet.Told with verve and wit, The End of Money explores an aspect of our daily lives so fundamental that we rarely stop to think about it. You'll never look at a dollar bill the same way again.
