The system is based on a central computer (10) which holds details, for each of a number of users, of visits to be made and a termination time for each. These details may be logged by the user calling on a mobile phone (16) and providing the details as a mixture of voice, held in a voice recording system (12), and keyed data held in the computer (10). In the event that the user does not confirm termination of the visit before the stated time, the computer (10) initiates a call to the user's mobile phone (16) and in the absence of a satisfactory response sends an automatic call to the telephone (18) of a designated person such as the user's employer.
