What are the economic consequences of digital cash? What are its implications from the view of economics? In recent years, several proposals for electronic cash have appeared in cyberspace. In several cases, forms of digital cash are already in use. The economic consequences of these transactions have not yet been fully examined. To some observers, one important economic consequence of electronic cash is the free 소액결제현금화 issue of private currency by commercial banks or other non-firms. However, if we look at the history of money, it is not easy to make privately issued currency credible in the eyes and wallets of the public.
