Apple Pay launched on October 20th, bringing Apple's wireless mobile payments system to the iPhone 6 and iPhone 6 Plus. At first, the system was limited to customers of major credit cards Visa, MasterCard, American Express; and to members of five big US banks: Bank of America, Capital One, Chase, Citibank, and Wells Fargo. Apple promised that it was bringing 500 other banks and financial institutions onboard as soon as possible, and several of those have started supporting Apple Pay as of today. PNC Bank, US Bank and Navy Federal, the latter the nation's largest credit union, have all enabled Apple Pay for their customers, as MacRumors noted.
Support for Apple Pay on USAA appears to have started today ahead of a November 7th target date. Barclaycard has also reportedly turned on Apple Pay for its US customers today, but we have yet to see any official notice from the company. Several other smaller credit unions are also said to have turned on Apple Pay as well. That's good news for Apple and new iPhone customers, especially in the wake of early Apple Pay duplication glitches and an upcoming rival payments system called CurrentC, which has been suffering issues of its own ahead of its launch.
