Apple will honor erroneous 6% Apple Card Daily Cash offer

Apple on Friday said a system error caused some Apple Card holders to see certain purchases as eligible for 6% Daily Cash, double the card's standard 3% cash back rate.

Apple informed Apple Card holders of the erroneous reward listings in an email on Friday, but said it will honor the 6% Daily Cash offer for customers who purchased an item displaying the incorrect rate.

"This was an error due to a system issue; however, in addition to the 3% Daily Cash that you already received for this purchase, we will be providing you with a one-time credit for an additional 3% Daily Cash back — totaling 6% Daily Cash for that purchase," according to the message, as relayed by Bloomberg's Mark Gurman.

Customers will see the credit Balance Adjustment in the Wallet app and on their October statement, Apple said.

The 6% Daily Cash rate appeared for a subset of users on Thursday. Apple did not announce an Apple Card promotion and while some customers saw the doubled cash back rate, others did not. The inconsistencies prompted some to question whether the offer was legitimate.

On Friday, a Reddit user said an Apple Support supervisor confirmed that the 6% cash back rate was posted in error. The representative added that Apple planned to revert purchase rewards to the usual 3% Daily Cash rate, which appears to be the case as the company is adding one-time credits as a post-purchase adjustment.

Adding to the confusion is Apple's history of leveraging Daily Cash promotions to drive new Apple Card signups. In March, for example, new Apple Card customers were offered 6% cash back on Apple products for one month.
