Apple just made a bunch of new announcements for Apple Pay, including its first overseas expansion

Apple just made a number of announcements at its developers conference for its Apple Pay digital payment service.

The big news is that it will expand to the UK market next month, making its first foray outside of the US. For the launch, Apple Pay is partnering with eight of the largest banks in the UK, supporting more than 70% of all credit and debit cards in the country.

Apple Pay will also be available in more than 250,000 locations in the UK, including retail stores like Marks & Spencer and Boots, which is more than the number of stores it was available in when it first launched in the US.

Another big announcement that drew a lot of attention: London's transportation service will now start accepting Apple Pay.

Jennifer Bailey, Apple's VP of Internet Services, shared the following updates on Apple Pay:

• There are 2,500 banks supporting Apple Pay now: Discover will also join Apple Pay this fall, which means all four major credit cards are part of it as well.
• Square will release a new Apple Pay reader: Apple and Square are working together to bring Apple Pay to millions of small business owners. As part of the partnership, Square is releasing a new card reader this fall, which has contactless NFC payment reading capability.
