Re: I'm puzzled by these attempts.
It is the card processor who pays Apple a very small sum per transaction.(0.015% if my memory serves me right)
The Card details are stored in the security chip on the phone. Then you auth the payment with your finger (yes, you are giving Apple the Finger!)
The difference between this and the other types of payment service is that the merchant does not see your card details. Thus they can't track your shopping habits!
For the likes of Tesco this is not good. I will very surprised if they sign up for apple Pay at launch.
Or is that why Tesco are selling their data analytics company?
