Piero Smart Door
As seen at: Abilities Expo - 10/27/2017

"Transform any ADA low-energy-push-activated door into a smarter door with
hands-free opening capabilities by adding our device, PORTAL."

"Using proximity technology, PORTAL recognizes your smartphone and opens
doors as you approach. You no longer need to go through the hassle of playing
hide-and-seek or pushing the buttons. It is a truly seamless experience."
