Abstract
A portable information handling system multi-purposes a near field communication (NFC) antenna to detect object proximity of objects by interfacing a capacitive proximity processor with the NFC antenna and isolating the capacitive effects at the NFC antenna with a capacitive matching circuit disposed between the NFC antenna and an NFC transceiver. Comparison of the objects detected proximate the NFC antenna and proximate a conductive antenna provides a distinction of different types of objects, such as human forms versus a desktop.
