A system and method for allowing a user to have card transactions on-line and/or off-line with a non-rechargeable electronic money card are provided. The card transaction system includes a card issuing unit which allocates a unique card number to each card and sets a card account corresponding to the card number to issue a card; a card adjustment unit which receives transaction details corresponding to the card and adjusts the card account corresponding to the card according to the transaction details; a flag generator which generates a flag, which indicates whether the card can be used, according to the balance of the card account, on the basis of an off-line reference amount set for off-line transactions and an on-line reference amount set for on-line transactions; and a card information transmitter which transmits the flag corresponding to the card. Accordingly, a time gap between an on-line real time transaction and an off-line transaction using batch transmission can be overcome so that network type electronic money can be used for both on-line and off-line transactions. |
