A:Answer I don’t believe it is designed to work with a wallet case. Most cases with QC capabilities will advertise as such. For example a majority of Otterbox cases are designed to work with wireless charging, as for the demagnetizing your cards, I don’t believe there is a magnet in the base for the phone, only for the watch as that is how it’s designed by Apple to charge. I’ve not had any issues with my cards being demagnetized by being in my stand alone wallet as it has a magnet in it to hold bills.
May not be what you’re looking for but I hope it helps a bit.
