IC CARD TRANSACTION SYSTEM

摘要

PURPOSE:To improve the operability by operating a specific key so as to re- input the data when transaction data is updated and it is not necessary to change the transaction data inputted once. CONSTITUTION:When a fixed information mark (*) is not given but an already inputted data exists, the already inputted data is displayed. When the operator agrees with the operation, the operator depresses a key with * mark. The key is included in input keys 7 of an IC card holder. When it is discriminated that the * key is depressed, the data is preserved and the processing corresponding to the next operating procedure is given. When the key is not the * key, the data inputted newly by keys are stored in a transaction data storage area corresponding to the operating procedure designated by the pointer at present as they are and the processing corresponding to the next operating procedure is given after the enter key is depressed.
