A portable information handling system glass ceramic housing integrates plural wireless charging coils on one side and plural coil interface traces on an opposing side that interface with conductive material disposed in through glass via openings. Conductive contacts interfaced with the coil interface traces and exposed at the glass ceramic housing interior couple to a printed circuit board assembly through pogo pins that bias against the conductive contacts to communicate power from the wireless charging coils to the charger of the information handling system. The conductive contacts co-locate with a logo etched into the glass ceramic housing to provide an aesthetically pleasing wireless charging solution.

A radio frequency identification (RFID) tag includes an antenna, an analog front end, a processing circuit, and memory.
