The electronic wallet used in the electronic currency system uses a character to be displayed on the display section when electronic money is exchanged between two IC cards storing electronic money using the electronic wallet. Look at the numbers and check the balance of the electronic currency, operate the numeric keypad to enter the amount of electronic currency to exchange, read the display "Move from card 1 to card 2", etc. I had to read letters and numbers and do a lot of key operations.

However, at present, when using cash to exchange the same currencies as described above, open the wallet to check the presence and amount of bills, count the bills by hand, and check the bill of the required amount. I'm doing work that can't be expressed with letters and numbers, such as taking it to a place.

Therefore, the work by the electronic wallet used for the above-mentioned electronic currency system is quite different from the current situation of using cash, and it is necessary to change the mind and operate with a new feeling.

An object of the present invention is to provide an electronic wallet for accommodating and carrying an IC card storing electronic currency used in the electronic currency system described above, and an electronic currency between two IC cards.

According to the present invention, the object is to provide an electronic wallet having an operation section and a display section for accommodating and carrying an IC card storing electronic currency. By displaying the balance of the electronic currency stored in the IC card on the display unit by an icon indicating the denomination of bills and coins, and by setting an IC card other than the IC card, This is achieved by transferring electronic currency between these two IC cards.

Further, the object is to configure the operation unit by a touch panel provided so as to overlap with the display unit, display icons showing the two IC cards on the display unit, and display the two IC cards. When the electronic currencies are moved to each other, it is achieved by determining the direction in which the electronic currencies are moved according to the order in which the icons corresponding to the IC cards are picked.

The object is to move the electronic currency by picking an icon indicating the denomination of the source electronic currency, so that the icon indicating the denomination of the source electronic currency is moved to the destination position. By displaying the moving animation, it can be achieved by displaying at least one of background color change, sound, vibration, and bulge of the wallet case.

Further, the above object is achieved by making it possible to arbitrarily specify an icon indicating the denomination of electronic currency displayed on the display unit.
