Dunkin Donuts, Kohls, Walgreens and several other merchants are going to start add support for store cards into Apple Pay. The news was announced during WWDC 2015 in San Francisco, where Apple also revealed it’s going to replace “Passbook” with a new app called “Wallet.”
The support for loyalty cards will allow you to pay and take advantage of retailer benefits using cards you already carry in your physical wallet. The UI is similar to what used to be available in Passbook with credit cards, and will allow you to flip through the cards you own. It should, however, also automatically bring up the right card in the store you’re trying to make a purchase in, like Dunkin Donuts.
Support will be available this fall, likely in tandem with the iOS 9 launch.
