InvisiCast holds 3 US patents. It is a screen-casting device for Apple & Android smartphones, tablets, and most all laptops. It requires no cables, and no Wi-Fi. InvisiCast is ridiculously easy to use--just plug one piece into your phone or tablet, and the other piece into a TV or projector. That's it. There's no 2nd step. InvisiCast casts every app you have, not just the paid subscription ones. It requires NO Wi-Fi to work. Invented, patented, and made here in the United States, InvisiCast is a unique, novel, cable- and network-free solution to classroom instruction, presenting evidence in court, conferring at a teaching hospital, and so much more. We are in final development of our smaller commercial device and are actively seeking grants and funding. Contact us at mason@invisicast.com for more info!
