Would it be possible to fix in a wireless charging adapter from eBay to the USB connector cable and if yes can you provide some instructions please. Is it possible to attach an NFC sensor via similar connection via USB cable attachment inside the back near the connector attachment once the screw's are removed please. Any walk through guide for such a mod and parts needed would be useful.

The spring contacts in the back are for swap covers. My swap covers have contacts on them while the original cover does not.
