The touch controller is expanding its capabilities beyond just input sensing. It is enabling / controlling high-speed communications between two phones via touching screens. Instead of using NFC to identify phones and Bluetooth or Wi-Fi to exchange data, Hot Knot technology is using the touch screen and touch screen controller to both identify and exchange data. Transfer rates up to 54Mbps are possible which is much higher than Bluetooth but not quite as high as the latest Wi-Fi.
