Can I make cash payments for my Apple Card at Apple stores?

Hi, no, that is not a service that is available. While the credit card is a co-branded card called Apple Card, the card is owned, issued and administered by Goldman Sachs Bank. All payments must be directed to Goldman Sachs.

Here is a support article on how to pay your Apple Card monthly statements,

You may also mail checks to Goldman Sachs Bank.

I hope this helps.
