Abstract

Portable information equipment has a device attachment detection section which detects whether or not a device is attached to a human body, an authentication data input section which inputs authentication data while the device is attached to the human body, a storage section which stores the authentication data inputted by the authentication data input section, a transmission section which transmits, the authentication data stored by the storage section, and an authentication data clear section which clears the authentication data stored by the storage section if the device attachment detection section detects that the device has been detached from the human body. After authentication data is inputted and stored in the portable information equipment, the authentication data can be transmitted by operating a switch once. Further, if the portable information equipment is detached from the human body, the authentication data is cleared. Thus, security can be ensured sufficiently.
