The radio frequency technology allows for a 200 foot range and does not need a "line of sight" with the ResponseCard keypads. The approximate size of a thumb drive, it doesn't require the hassle of cables and is easy to transport from room to room or class to class. With 4 gigabytes of storage, you can store presentations and even the TurningPoint software for easy access. The RF+ Receiver can gather up to 1000 responses at once. For use with TurningPoint assessment software and ResponseCard RF, ResponseCard RF LCD and ResponseCard NXT clickers.
