Apple today shared a video of how they made the titanium Apple Card
With Apple Card you can make digital Apple Pay payments, but Apple is also providing a physical card. Since this is a credit card designed by Apple, it is, of course, unique among credit cards.
It's made entirely from titanium, which is laser etched with your name. The front of the card does not have a card number or an expiration date listed, and on the back, there's no CVV and no signature. If someone finds or steals your card, there's going to be no real way for them to use it, at least for online purchases.
There's still a traditional magstripe on the back, along with a built-in chip for chip and pin purchases. While the card number and CVV are not on the card itself, you can find them in the Wallet app if you need them.
When you actually get your physical Apple Card, you'll be able to tap it to the iPhone to activate it, so you won't need to place a phone call for activation like you have to do with existing credit cards. The physical Apple Card will not support contactless payments -- you need to use your iPhone for Apple Pay payments.
There is no cost for the card and there is no fee associated with replacing it if you lose it.
