Bailey also talked about a broader effort to add loyalty programs to Apple Pay. Walgreens loyalty program should be added to Apple Pay soon, and there are plans in place to support programs from Kohl's, Coca Cola, Whole Foods, Panera Bread and much more as well. One of the issues of adding loyalty programs like these is that it often requires an upgrade to the point-of-sale terminal so the process will likely take some time. There are also plans to support even more department store cards, which are also often used as loyalty cards. "You'll see many more large merchants adopt Apple Pay because of our ability to support store cards," she said.

There are other avenues for Apple Pay beyond just the retailer too. In-flight mobile payment could be a growth area in the future, as she mentions that you can already use Apple Pay in JetBlue flights and Delta has just incorporated Apple Pay in its app today. They're also looking at incorporating Apple Pay in gas stations.

"We see an acceleration in adoption in merchant acceptance," she said, adding that the company is continuously working on more partnerships.
