Australia's big banks have failed in a legal attempt to open up the iPhone's NFC features to outside developers, meaning that Apple Pay will remain the dominant biometric mobile payment system on the devices.The Australian Competition and Consumer Commission (ACCC) denied the request made by CBA, Westpac, NAB, and Bendigo and Adelaide Bank.”The ACCC is not satisfied, on balance, that the likely benefits from the proposed conduct outweigh the likely detriments. We are concerned that the proposed conduct is likely to reduce or distort competition in a number of markets,” ACCC chairman Rod Sims said in a statement.”While the ACCC accepts that the opportunity for the banks to collectively negotiate and boycott would place them in a better bargaining position with Apple, the benefits would be outweighed by detriments.”The four banks wanted access to the NFC chips in Apple's iPhones in the same way they access the technology in Android devices so they could offer their own integrated digital wallets to customers.
