ABSTRACT:
In an IC card system, a first file corresponding to a normal bank account and a second file corresponding to an IC card account are provided for each IC cardholder. A card terminal for receiving an IC card communicates in an on-line manner with a host computer installed in a bank. A deposit amount is transferred between the first and second files for a transaction using the IC card. The IC card stores an account list for the transfer of a remittance to an account of a third party, so that a cash transfer from the first or second file to the account of the third party can be performed. The IC card functions both as a debit card and a credit card. When either of these functions is selected, an off-line transaction involving use of the IC card can be performed.
