This has some cool anonymity properties. You can generate the Moon card without KYC (using only email and funding it with your non-KYC sats). Then when you connect it in the phone, both Apple and Google then generate anonymous card number during payment. So the seller won't even know that you had Moon card to start with. Of course you need to have anonymous Google or Apple account on your phone - if you are connecting this with your personal account, then you don't really gain much.

(but I also agree with @DarthCoin that "fuck those shit cards", and I'd suggest you follow what I said above only if your life depends on it...)
