The SurfacePad for iPhone 12 from TwelveSouth might just be the perfect wallet case for your iPhone.
Apple FineWoven MagSafe Wallet Review – Really Apple?
This new case is an update to TwelveSouth’s long-running SurfacePad line. It’s now custom-molded for the various iPhone 12s, but it’s also MagSafe compatible, with a twist. The case still sticks to the back of your iPhone with adhesive, not magnets, while MagSafe compatibility lets you charge the phone through the case with one of Apple’s charging pucks.
This setup is ultra-slim, ultra-secure, and looks great too.
