A fingerprint reading mechanism is utilized so as to determine which audience members are present during various stages of an audio, visual, or audiovisual program. The fingerprint reading mechanism is associated with a processing mechanism, an “enter” button, an “exit” button, a clock, memory, an output indicator, and a code receiver. As an audience member enters or exits the program performance area, the audience member places a hand, or portion thereof, in proximity to the fingerprint reading mechanism, and also presses the “enter” or “exit” button as appropriate. Optionally, the functionalities of the “enter” button and the fingerprint reading mechanism may be combined into a single automatically activated enter/fingerprint reading mechanism, and the functionalities of the “exit” button and the fingerprint reading mechanism may be combined into a single automatically activated exit/fingerprint reading mechanism. The fingerprint reading mechanism generates a fingerprint data record in response to a human hand, or portion thereof, held in proximity thereto. The processing mechanism compares the generated fingerprint data record with each of a plurality of stored fingerprint data records accessed from memory so as to permit retrieval of an audience member identifier corresponding to the generated fingerprint data record. An audience log entry associates the retrieved audience member identifier with a corresponding clock time parameter and a corresponding enter/exit parameter. In response to retrieving an audience member identifier from a generated set of fingerprint data, the processing mechanism creates and stores an audience log entry by loading the current value of the clock as the clock time parameter.
