Owners of newer iPhones can make mobile payments at more than 2 million retail stores, according to Apple.
Some of the latest adopters include Au Bon Pain, Chick-fil-A, and Crate & Barrel. The service is gaining traction within third-party apps, too, as companies including Zappos add Apple Pay to their own applications.
Using Apple Pay within apps makes it easier to pay, as consumers don’t have to fill in credit card details each time they make a purchase. Apple Pay launched at 700,000 locations in 2014. The company met its goal of reaching 1.5 million locations by the end of 2015, and is pushing for broader adoption by retailers around the globe.
Apple Pay is available to the iPhone 6, 6 Plus, 6s, and 6s Plus.
