I’m mostly having fun, but Apple’s official wallet also has magnets on the back. The point is apple designed a system where a small removable wallet needs to be handled with your cards. That’s apple’s system design. And I suspect that you would encounter the same issue with Apple’s official wallet. Just like my Popwallet apple says the inside of the wallet is shielded. But the outside cannot be shielded as it has to magnetically attach to the phone. So unless the apple wallet has much weaker magnets, in which case it would fall off the phone easily, then it’s going to have the same issue. The problem is with the system apple designed.
Is it? Numerous people up and down this thread who do use the official one have told you they've not experienced it, so I'm not sure your assumption holds.
They’ve not experienced the issue when touching a magnetic card to the magnetic side of the wallet, or they’ve not experienced the issue when placing the card in the shielded section? Because what I’m saying is the former is unfortunately very easy to do, and that would be easy no matter which brand holder is used.
