This will get you all the parts you need for a DIY kit. This includes the 3 pogo pins, the pin holder (this will ensure they are spaced properly so it lines up with the contacts on your phone), the micro USB receptacle, the wires you need to make the connections, and a programmable NFC sticker.
This will get you 2 DIY kits.

If you're really not good with your hands and would rather that I put the whole thing together for you, you can pledge $80 or more. This will get you a Samsung Car dock with the 3 pogo pins installed and ready to charge your phone, and an NFC chip inside the dock which you can program to whatever you'd like.
