Abstract: A terminal system includes first and second terminals (7, 8 and 3a respectively). The terminals can be connected to a central equipment and the first terminals are used for a first functional mode, for example passage control, where persons allotted identification cards can insert information into the common central equipment. The first and second terminals and the central equipment are arranged for a second functional mode, which operates in parallel with the first functional mode. The messages are inserted into the central equipment via the second terminals. Respective first terminals are provided with indicators (6b, 6", 7a, 8b) which can be activated when information relating to a particular person is stored in the central equipment and this particular person, in order to carry out a procedure in the first functional mode, simultaneously activates the first terminal with the aid of his/her identification cards.
