Abstract
Recent years have witnessed the increasing penetration of wireless charging base stations in the workplace and public areas, such as airports and cafeteria, to allow users to charge their mobile devices. Such an emerging wireless charging infrastructure has presented opportunities for developing new indoor localization and identification services for mobile users. In this demo, we present QID, the first system that can identify a Qi-compliant device during wireless charging in real-time using features extracted from the clock oscillator and control scheme of the power receiver. QID employs 2-dimensional motion unit to regulate the inductive coupling between the power transmitting and receiving coils, which allows for fine-grained device fingerprinting.
