PURPOSE: To change an identification code on the spot without needing complicated procedure by storing a registered identification code of each user by registers or a read-write storage device such as a RAM. CONSTITUTION: Four registers 4a-4c are provided to take charge of storage of the cipher number of each registered user, temporary storage of information such as an inputted cipher number and password, temporary storage of a card number and tempoerary storage of a reloaded cipher number respectively. When required matters are inputted in specified order through a ten-key 10, the password is collated, and whether there is a duplicate cipher number is confirmed. If there is no hindrance, an old cipher number is deleted, and a new cipher number is registered. A RAM can also be used instead of the registers 4a-4c. |
