The users will be able to link credit cards to their Apple IDs and pay simply by scanning or tapping a device over an NFC terminal.
We just cant wait to see how the iOS 8 will participate in the evolution of the Apple products but from what we have seen lately, we can tell that things are shaping up very interestingly. Thanks to the numerous leaks earlier on, we have come to know that health and home automation would form major parts of the devices which has been confirmed by the respective introductions of HealthKit and HomeKit at the WWDC event. Another interesting development is the NFC being part of most of the apple devices which indicates that the new iOS will welcome mobile payments.
This is something that The Wall Street Journal has also been commenting on and even previously hinted that both the iWatch and the iPhone would show a push towards e-payments. This is not something new considering that this option has been offered in the Android domain for quite some time now, there is still a strong spark because it is coming from “Apple”. WSJ also focuses on the importance of NFC and how it will be pivotal for the tap-to-pay method. This means that the users’ Apple IDs would be linked with the credit cards and they will be able to make payments simply by scanning or tapping a device over an NFC terminal.
