“The End of Money” is the title of David Wolman’s provocative book, which explores a world without cash. Could our economy exist without bills and coins? Do we need a mint?

David has traveled the world seeking answers and he has learned that replacing unnecessary currency with digital records could save us over $1 billion per year!

But will this result is an even more complete loss of financial privacy, or has that already happened?
