Abstract
An electronic wallet includes a plurality of operating keys at least having a plurality of numeric and calculation keys, a display part for displaying thereon electronic money information and IC card state information, at least one independent function switch in addition to a power switch, a plurality of control keys for operating the electronic money information stored in IC cards and the IC card state information, and a plurality of function keys having a plurality of function level layers having a plurality of tasks, for selecting the plurality of tasks having the respective function level layers. Thereby the electronic wallet can have many functions. Further, a modem unit, which is removably mounted to card slots of the electronic wallet, is provided with a through opening to communicate with the card slots and a modular jack to be connected to a communication line. Since a user can insert the IC card into the electronic wallet from the card slots with the modem unit already mounted to the card slots, handling of the electronic wallet is convenient upon transfer of the electronic money through the communication line. In addition, the user can insert the IC card into the electronic wallet which is still connected to the communication line.
