Three of the largest banks in Australia have filed a joint application with anti-trust regulators to negotiate with Apple over Apple Pay restrictions and install their own mobile payment application on iPhones. The three banks include National Australia Bank (NAB), Commonwealth Bank of Australia, and Westpac Banking Corp.

Smaller banks like Bendigo and Adelaide Bank have also joined the three major banks in their application to the Australian Competition and Consumer Commission.

Apple Pay is completely closed for third-party integration, so it is currently not possible for banks to promote their own mobile banking app through it. In comparison, Samsung Pay and Android Pay accept third party app integrations.

The banks in their joint application argue that by limiting the use of NFC inside the iPhone to its own mobile wallet solution, Apple is stifling competition. All the three banks are yet to support Apple Pay, which launched in Australia earlier this year. ANZ is the only major bank in the region to support Apple’s mobile payment system.

Mobile payment systems are going to change the face of banking in the coming years, and by limiting Apple Pay, the Cupertino company is trying to be right in the middle of the action and rake in some additional moolah.
