ABSTRACT:
Apparatus for controlling and recording the use of a plurality of photocopiers are disclosed. The apparatus includes a terminal associated with each of the photocopiers and a central recorder connected to each of the terminals. Each authorized user of the photocopiers is issued a badge having user identification information encoded thereon. The information on the badge is read at the terminal and transmitted to the central recorder before the copier is used while counts made at the terminal and representing the copies made are transmitted to the central recorder after the user has completed making his copies. A communication link between an individual terminal and the central recorder is only required immediately prior to and following the use of the copier by each user.
