Apple Pay was announced yesterday alongside the Apple Watch, iPhone 6 and iPhone 6 Plus. The proximity-based mobile payment system taps NFC hardware and Touch ID to authenticate payments, using the iTunes billing backend and credit cards stored in the Passbook application.

The service is viewed as a potential new revenue stream for the Cupertino firm which has managed to negotiate deals with banks that will allow it to collect transaction fees when a user makes the purchase,according to Bloomberg.

Some of the big banks participating in Apple Pay include JPMorgan Chase, Bank of America, Citigroup and others.

The market for in-store mobile payments is set to quadruple to roughly $90 billion by 2017, according to a recent study conducted by Forrester Research.

Using Apple Pay on older iPhones from the iPhone 5 onward will require an Apple Watch, the company confirmed. The service isscheduled to launch sometime in October.
