ABSTRACT:
An event counter and access controller system has a central processor unit, memory storage, and operator's keyboard, display, badge reader and key switch. The system may operate in a normal mode, wherein copy pulses from a photocopier, for example, are counted and stored in individual user accounts; and in a set-up mode, wherein accounts may be sorted and examined, may be made accessible or inaccessible, and may have their contents changed. When receiving count copy pulses from an event to be counted, the system certifies the validity of the pulses by filtering and sampling techniques. When an access card is inserted in the badge reader, the system validates and accounts for skew tolerance of the card.
