PURPOSE:To quickly process data, and to eliminate an input mistake to re-input it by storing previously input data for transaction processing in a storing means, and in the case of abnormal termination, taking out this data and changing only the data necessitated for change. CONSTITUTION:A RAM 13 includes A, B, C-registers 31, 32, 33. The A-register 31 stores logic '0' when the data inputted at a previous time was processed normally, and stores logic '1' when the processing of the data inputted at the previous time was abnormal. A CPU 11 displays a personal identification number inputted at the previous time on a display 16. If the personal identification number is wrong, the correct personal identification number is inputted from a PIN pad. The inputted personal identification number is stored in an area 344. If the displayed personal identification number is correct, the personal identification number inputted at the previous time is made valid by operating an enter key. Thus, only the data necessitated for the change is changed, and the re-input of the rest is made unnecessary. |
