Apple co-founder Wozniak says Apple Card algorithm gave his wife a lower credit limit than himself

Apple co-founder Steve Wozniak joined in the online debate over accusations of gender discrimination by the algorithm behind the iPhone maker’s credit card, fuelling scrutiny of the newly-launched Apple Card.

The criticism started on Thursday, after entrepreneur David Heinemeier Hansson railed against the Apple Card in a series of Twitter posts, saying it gave him 20 times the credit limit his wife received.

The much-anticipated titanium credit card, part of a broader effort by Apple to derive greater revenue from services after years of heavy reliance on iPhone sales, was launched in August, in partnership with Goldman Sachs.

In an email, Goldman said Apple Card applicants were evaluated independently, according to income and creditworthiness, taking into account factors such as personal credit scores and personal debt.

It was possible for two family members to receive significantly different credit decisions, the bank said, but added, “We have not, and will not, make decisions based on factors like gender.”

Hansson, who is the creator of web-application framework Ruby on Rails, did not disclose any specific income-related information for himself or his wife but tweeted that they filed joint tax returns and that his wife had a better credit score.
