A system for contact services enables face-to-face contacts between two or more persons immediately or almost immediately when their profiles match, i.e. they have similar requirements or interests. The system includes at least two devices termed "contact device". Each person, who wishes to use a contact service, carries a contact device with him/herself. Each contact device is equipped with a low-powered receiver for receiving information and an alarm which signals when the person's profile and another person's profile match. The contact device signals, for example, by beeping, by vibrating, or by blinking a small-sized light. By using a contact server it is possible to enlarge the area from which persons may receive either profiles or information concerning matching profiles. Profile mediators are intended for transmitting person's profile and the state information to the contact server.
