<DIV>The age of paper dollars and metal coins is coming to a close. In <i>The End of Money</i>, David Wolman introduces the people, technologies, and trends powering this shake-up, taking us to hotspots of the cashless revolution. He zooms from the cash-strapped slums of Delhi, to the tech-obsessed streets of Tokyo, to London to hobnob with digital cash gurus. Then it&#8217;s on to Reykjavik, where Icelanders are about to kill their national currency; Washington, to learn about high-tech counterfeiting; and Los Angeles, where scientists study our brains on cash. Along the way, Wolman examines the implications of next-generation payment innovations, investigates alternative and virtual currencies, and showcases the boon in mobile-phone banking.<p>As cash gets pushed toward extinction, now is the time to explore its effect on our wallets and our lives.</DIV>
