Apple is making a big push to get Apple Pay in more places.

Apple Pay is expanding to the U.K. next month with more than 250,000 locations. Commuters will also be able to use Apple Pay for transit fares in London, making it the first transit system to support the mobile payments service.

The company is also expanding Apple Pay within the U.S. Already, Apple says over 2,500 banks now support its digital payment method, and soon Discover will as well. The company is also adding more merchants to its roster, including Forever 21, Trader Joe’s, and JCPenney.

To attract more small business owners, Apple is teaming up with Square on a new mobile payment reader that will accept its signature tap-to-pay solution. Square’s new reader will debut this fall and the company says it will be giving out 250,000 Apple Pay enabled readers for free.

As was announced last week, Pinterest is launching Buyable Pins, and Apple confirms that the checkout process will support Apple Pay.

Finally, Apple is launching a rewards program through Apple Pay. Kohl’s, JCPenney, and Walgreens are some of the earlier adopters of the new loyalty and rewards program. Dunkin’ Donuts will bring perks to Apple Pay this fall.
