The fault of a paper money currency / the coin currency does not circulate if I forget it somewhere. When Japanese citizen alone forgets 10 yen to a slightly old money box, about 1,200,000,000 yen will not circulate. With the liberalization of the enten, I explain that I take place of electronic money from a paper money currency / a coin currency. I lose the electronic money, and it is not forgotten to an old money box.
