Well I just read my untouched Mario Amiibo with my HTC One M8 and this.
EDIT: Also running Cyanogenmod.
Not sure how accurate data reading is, it (kinda) matches up with what the Pokemon Rumble U info is (http://wiiubrew.org/wiki/Wii_U_GamePad)

I copypasted the datablob into a hex editor, doesn't seem readable at first, but who knows. Also, keep in mind, this has never touched a Wii U, I just took it out of the package.
