Individual negotiations between Apple and card issuers around the world have failed due to Apple's large market share in countries like Australia. A collective negotiation approach would create a more powerful negotiating party and be more fair and efficient. Banks argue that Apple relies on their infrastructure for payments but Apple points to their experiences in Canada and China as examples and their impending rivalry with Google in mobile payments, which are subject to rapid market changes in technology like NFC functionality that could drive innovations. Challenges in negotiations include differences in mobile payment infrastructure, regulations, transaction fees, costs, and income disparities between countries.
