IC card with keyboard for prestoring transaction data

摘要

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. A skip code is entered for portions of transaction data that is not pre-stored. An automatic transaction processing unit reads the transaction data stored in the card and receives from the customer any additional data which was not previously stored in the card (e.g. data associated with the skip code) and which is required to complete a transaction.
