Apple Pay gets a big upgrade to speed up your impulse buys in third-party browsers and apps

Apple Pay is getting the ability to give users a way to access installment payment loan services and view and redeem rewards when making a purchase online in iPhone and iPad apps. 

Many websites support the ability to make payments with Apple Pay, with it being very easy to pay via an iPhone – tapping on an Apple Pay option will trigger the native Apple Pay interface letting payments be charged to the selected or default credit or debit card and approved via a double-click of the home button and Face ID. But they offer only cash transactions rather than allow more options, such as paying in installments.
