Abstract: A method for extracting revenue information from a Point of Sale terminal for purposes of revenue sharing includes the step of examining data traffic in a conventional Point of Sale operating system. This operates in the background and allows extraction of select data relating to revenue traffic in a rental system. Data stored in a video buffer (54) is examined and, upon a predetermined transaction completion event then occurring, this data is extracted and stored in a separate capture file. This capture file is utilized to generate a revenue sharing data base, which is transferred to a remote revenue sharing transaction system. The transaction completion event is a keystroke that indicates completion of a transaction at the Point of Sale terminal.
