The lightweight, rugged, durable ResponseCard has been rigorously tested in classroom environments. The result is optimized portability. ResponseCard RF is compatible with TurningPoint assessment software.No ResponseCard clickers include a license. Most classes do not use paid software and this is not necessary, so Turning Technologies does not include it with all clickers. It must be purchased separately through your school's affiliated Turning Technologies store. You do not need a license unless your professor specifically says you do.
