A current password storage unit for storing a password which has recently been input and the password identification information of the password is arranged. When one application is selected, password identification information corresponding to the application is verified with the password identification information stored in the current password storage unit. If the two password identification information match, key verification is performed using the password in the current password storage unit. With this operation, a plurality of data can be read out by performing the password input operation once. One or two select keys are arranged in place of a ten-key pad.
