Redditor u/mdhardeman did some digging into the Apple Card. After running a test transaction they found that the card was listed as a Mastercard World Elite.
The Mastercard World Elite consumer credit cards are significantly more expensive to accept than a plain Mastercard credit card or basic rewards card. In exchange, the theory goes, Mastercard ensures that those cards only make it into the hands of premium consumers who, on average, spend more on many purchases and have a larger amount of disposable income. In exchange, Mastercard demands the higher reimbursement for the card issuers to be able to fund a benefits package that will attract heavy spenders to their World Elite card products.
