CHARGE AMOUNT CHANGE METHOD OR CHARGE AMOUNT DETERMINATION METHOD, AND E-MONEY CHARGER

PROBLEM TO BE SOLVED: To provide a charge amount change method or a charge amount determination method, allowing money amount designation without providing a new input device for the designation of a charge amount, in an e-money charger. SOLUTION: When putting in cash (S11) and thereafter touching a card to an antenna part (S12), the charger reads the card and displays a balance (S13). The charger determines an amount capable of being charged to the card (S14). A put-in cash amount or the like is displayed on a screen (S15). When it is confirmed that the card is identical to a card used at the beginning (S18) and when communication with the card breaks off before passing over a unit money amount change decision time (S20: No), the charger decides that a user has an intention to change a charge designation amount to add or subtract a value corresponding to a designation money amount change unit amount (S21). When keeping on touching the card, the charger decides that the user desires a charge of the presently designated charge designation amount (S23). COPYRIGHT: (C)2010,JPO&INPIT
