Starting September 16, through the end of the year, Discover cardmembers using Apple Pay will automatically earn an extra 10% Cashback Bonus on up to $10,000 of in-store purchases. Discover it Miles, Miles and Escape cardmembers will earn an extra 10 miles per dollar on up to $10,000 of in-store purchases.

For those cardmembers who have the Double Cash Back promotion on their card–also available to new cardmembers who apply by the end of September–this extra 10% bonus should also be eligible for the double cash back, making it possible to earn 20% cash back on their in-store Apple Pay purchases (on their first $10,000 of in-store purchases.)

What is Apple Pay?
Apple Pay is a mobile payment and digital wallet service by Apple that lets users make payments using the iPhone 6, 6 Plus, 6S and 6S Plus, Apple Watch-compatible devices (iPhone 5 and later models), iPad Air 2, iPad Pro and iPad Mini 3 and 4. In supporting Apple Pay, Discover joins Visa and MasterCard in the US as supporting card types for the contactless payments service.

Apple Pay / Discover Requirements
This promotion does require an upgrade to iOS 9, which is not available until September 16. Apply Pay also requires an iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus or an Apple Watch when paired with any of the aforementioned devices, or the iPhone 5, iPhone 5c, or iPhone 5s.

For those concerned about security, Discover cardmembers who use Apply Pay will receive all the same protections, services and benefits as they would when normally using their card.
