Wallet is an app, like every other bank app, except it offers more privacy than any other I’m aware of. If I open my Citibank, Chase, Wells Fargo, 5/3, Capital One, Discover, American Express, Regions, PayPal, Venmo and Cash App, front and center is every savings account, checking account and credit card account balance I have with the respective bank. Apple Wallet requires an additional tap to get through Apple Card and to Savings account. Effectively giving you one last chance to really question if you should be looking at your financial information in public.
Which is the real question, why are you opening your financial information in public? You say you want more privacy, then stop opening your private financial information in public. You’re just setting yourself up for being a target for theft or worse. Any additional layer of security won’t stop you from doing things in public that should be done in more private locations.
