The card, which will be linked with Apple's Wallet app, will allow users to set spending goals, track rewards, and manage balances, WSJ said.

The new cards will be rolled out to employees for testing in next few weeks and will be launched later this year.

The deal will benefit both the companies tap into new income sources. Apple has been sharpening its focus on its services business, including the App Store, mobile payments and music streaming after a recent dip in iPhone sales, which generate most of the company's profit.

Goldman is also looking to increase its consumer loans to offset dips in its trading business.

Apple did not immediately respond to Reuters' request for a comment. Goldman declined to comment.

The joint card, which will use Mastercard's payment network, offers a cash back of about 2 percent on most purchases. Spending on Apple products and services could potentially result in more cashbacks, some of the people told WSJ.

Goldman Sachs has already started adding customer-support call centres, and building an internal system to handle payments, a project that could cost the bank $200 million, WSJ said, a time when banks are focused on reigning in expenses to boost their bottom lines.

The Wall Street bank could eventually offer other financial products, such as Marcus loans and wealth management services, to Apple customers, WSJ said.
