9to5Mac reports starting today, Discover card holders can now link their accounts to Apple Pay. The only caveat here is that the iOS 9 update is mandatory to use the feature with Discover. Discover member's also have an added incentive to use Apple Pay, as the financial services company is promising 10% cashback on in-store purchases up to $10,000.
Unfortunately, due to the unexpected delay of watchOS 2, the Apple Watch will not be able to use Apple Pay with Discover until the update is finally released. Folks using the iPhone 6 or 6 Plus NFC technology will have no problem using Discover on iOS 9.
