Abstract
An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. An automatic transaction processing unit reads the transaction data stored in the card, checks to determine what transaction data, if any, which is required for the processing of the transaction is not stored in the card and, if necessary, receives from the customer any additional data which was not previously stored in the card and which is required to complete a transaction.
