The disclosed system and method provide a dynamic and scalable gaming system in which a plurality of gaming machines are connected to a network switch to form a hybrid peer-to-peer gaming network. The sensor may be a sensor coil mounted on the perimeter of the lower end of the casing, while the detectable device may be a transponder capable of emitting Radio Frequency Identification signals to the sensor to signal its arrival at the lower end of the casing. The apparatus detects the bio-couple by converting a change in mechanical properties before and after the bio-coupling based on electromagnetic induction to detect a bio-couple. Also, a handheld electronic device having one or more routines that are adapted to implement the method described above.
