As you may know, Apple unveiled iOS 9 today, and that includes some updates to Apple Pay.

For one, Discover will come on board starting in the fall, at which point Apple Pay will work with all major credit card networks. Also coming on board is Square, which will launch a new reader that accepts Apple Pay.

Next month, Apple Pay will be accepted at over a million locations in the U.S., which is four times more than when it launched. According to the company, merchants are seeing over a 2X increase in checkout rate among customers using Apple Pay in apps.

Later this month, users will be able to buy stuff from stores on Pinterest thanks to integration with Buyable Pins.

Apple Pay will also launch in the U.K. next month. By this fall, it will work with about 70% of credit and debit cards in the U.K. Over 250,000 locations in the U.K. are already ready to accept it.

Apple also announced that it has renamed Passbook to Wallet.
