Abstract
An IC card for credit transactions and a credit transactions apparatus and method using the IC card are provided. In an IC card for credit transactions includes a data memory portion and a controlling portion for reading out or recording data in the data memory portion, the data memory portion includes a user information area for recording information on the identification of a user, a transaction limit information area for recording information on the off-line transaction limit of the user, and a transaction particulars information area being divided into a plurality of sub-areas and for recording information on the transaction particulars of the user. Transactions using the credit card within the usage limit range set according to the credit rating of a customer are processed off-line, so as to reduce not only the load applied to the host system of the credit card company caused by the on-line transaction but also the time delay by the transaction approval, while minimizing losses (due to non-payment) of a credit card company and retail outlets caused by off-line usage by additionally recording special information on the IC card, such as delinquent payments, to restrict off-line credit transactions.
