The Bizz Button concept is currently packaged into mouse buttons as a way to prove that that the RF technology will fit in your hands.

These buttons are simple to use.  One player operates the base station, resetting it before asking a trivia question.  When the question has been asked, players can push their Bizz Buttons if they know the answer.  To determine who buzzed in first, the corresponding LED lights up on the basestation.
