Redbox Apple Card incompatibility
If you use the Redbox app to reserve your movies and use the Apple Card number in your Redbox account, the physical card will not recognize you when you swipe it at the kiosk. The number encoded on the physical card is not the same as the credit card number in the wallet app. I have contacted Apple and Redbox about this. You will probably see this same issue if ordering something online or over the phone and have to present your credit card at a local merchant to pick up your order. Only the last 4 digits of the physical card number is available to the account holder in the wallet setting.
