Abstract
PURPOSE:To improve secrecy by executing a specified scramble to a code number to be stored to a card and other data based on the code number, changing an attitude and storing it. CONSTITUTION:A card is inserted to a card writing/reading machine 11 and the code number and the other data are inputted by a keyboard in an input device 15. Then, a CPU13, a writing/reading control circuit 12, a filter 14 and the card writing/reading machine 11 are operated and the specified scramble is executed to the input data. Then, a writing to a card 1 is executed. The card 1 is inserted to a card reading/writing machine 21 of a terminal equipment 20 or the code number is inputted in an input device 25 and the stored data are read by a reading/writing control circuit 22 and a CPU23. Then, a reverse change to correspond to the scramble is executed based on the input code number in the CPU23 and the recording data are restored and sent to a central processing unit 26.
