Watch on. The Steps: 1: Plug in you NFC reader/writer into the port on your computer. There should be a light on it that lights up red. When putting an NFC item on the platform the unit should beep and the light should turn green, .I'm asking due to a mistake I made while cleaning the inside of my Wii u gamepad. I accidentally disconnected the wire that connects the NFC reader and the main board, and now I cannot use amiibos and other things. Would it be possible to use something such as the 3ds .
