ABSTRACT:
A paging receiver comprises an ID memory storing an ID number assigned to the receiver. If the ID number stored in the ID memory is coincident with an ID number stored in an ID card which is to be attached to the receiver, a received or stored message is displayed. If they are not coincident with each other, the received or stored message is prevented from being displayed. Thus, unauthorized access to the message can be prevented.
