Yes, it's not a much talked about feature, in fact I forget it was even possible. Qi charging pads are never included with phones, but as a consolation the pad will work with any future Qi compatible phone you buy. But the backs sometimes cost extra-- the idea is why raise the product cost further for folks who'll never use the wireless charging. Samsung's own S-View flip cover supports wireless charging: http://www.samsung.com/us/mobile/cell-phones-accessories/EF-TN900BBESTA . Any Qi compliant charging pad will work. The back cover you found should also work.
