Of course, the Apple Pay card will integrate with Apple's Wallet app bringing with it extra features including money, debt, and rewards management tools. Execs may borrow visuals from Apple's Health app, including "rings" that track your daily spend and notifications that alert you if you go over your set money targets.

Goldman, meanwhile, is hoping the venture will attract Apple's loyal fanbase to its Marcus online bank. It's reportedly splashing $200 million on the card's back end infrastructure, from customer-support call centers to an internal system to handle payments. Cardholder perks will apparently include cash back of about 2 percent on most purchases and possibly even more on Apple's devices and services, which the tech giant is set to expand courtesy of an incoming news subscription service and a video streaming platform. The card will use Mastercard's payment network, which is second only to Visa in the US, according to WSJ.
