Abstract

PURPOSE:To evade the danger of tapping messages and to improve the secrecy by securing such a constitution where a personal identification number PIN is put into a radio transmission line and the relevant message is never read unless said PIN is applied at the pager side. CONSTITUTION:A pager displays an incoming state via a speaker 8 when the coincidence is obtained between the call number of the signal received by radio and its own call number. At the same time, the pager stores the PIN data following a selected call signal and the message data into a RAM 17 via a CPU 19. Furthermore the pager displays a request on an LCD 12 for input of the PIN. Thus a user knows the incoming state and looks at the display of the LCD 12 to know that a message is secret. Then the user supplies his/her own PIN via a keyboard 20. A PIN collation circuit 21 collates the data on a PIN memory part 18 with the input PIN. When the coincidence is obtained from this collation, the CPU 19 displays successively the messages on the LCD 12. The pager is locked in case the PINs are wrong twice or more and the following actions are inhibited.
