Abstract
A compact electronic wallet, which is intended for easy operation based on a reduced number of keys, has an LCD display window, only keys including a cross key used for the entry of password number and amount of money transfer, Function key and Enter key on the top of the casing, and two IC card slots on the upper and lower sides of the casing. The user's own IC card is put into the lower card slot, which is normally closed by a hinged card cover, and held inside the casing, while other IC card is put into the upper card slot for electronic money transfer. Power is turned on in response to the operation of any key and turned off on expiration of a certain time after the last key operation.
