Here's how high quality Reply systems work (and work reliably...)

The computer tallies the responses from the base station and instantly displays them for the presenter or the entire group to see. Data can be shown as either total group feedback, individual responses, demographic units, and scores, or team standings.

When a participant enters a response on the keypad it is transmitted to the base station unit via radio frequency. The keypad then receives a message confirming the entry was successful and the base station transfers the data to your PC.
