Friends recently bought a set, external charger and battery, and for opening so often the back door of D3 noticed that has 4-pin gold-colored furniture, and I was curious to know what they are about. anyone have idea?

Sorry for my poor inglish

They are contacts that connect to the optional wireless charging back, which allows you to put the phone down on a pad like this to charge the phone: Energizer Inductive Charging Pad | Charging Station | Qi Technology

this guy is pretty interesting, will be that I could put it over the pad without the need to use an extra layer on your phone?
