The SE is a low cost, single event use keypad designed specifically for the meetings and event industry. The keypad utilizes the same, reliable radio frequency technology as other audience response devices, it has been reengineered to incorporate major cost reductions that ensure reliability while shortening its usable lifespan. Its short term life up to 10 days and low cost eliminates the need for post-event collection or management of devices.

The SE operates on patented 2-way radio frequency (RF) technology. An LED light on the keypad indicates that responses have been received. ResponseCard SE features a simple, five button input to facilitate easy participant responding. Its light weight and compact size allows for comfortable transportation from room to room or across multiple venues. Devices can also be returned to Turning Technologies in order to be recycled responsibly.
