Apple charges 0.15% and this is already included in the merchant fee that's that's 2-3%.
There is a lot of opposition from merchants to raising that fee, so the banks are absorbing it (because they think they'll save more on fraud prevention).
Apple also charges 0.5 cents per debit card transaction.
Currently, Interac charges its members 0.6 cents. So if Apple dealt with Interac, those fees would have to almost double. Can't see that happening.
If Apple wants money from payment processors further up the line, who get about 5 cents per transaction, they still want too much at 10% of that.
I'm sure the UK, Germany and other countries in Europe will get Apple Pay in 2016, if they don't get it this year. European governments, banks and regulations can be a hindrance for Apple so don't direct all/most of the blame toward them.
It's even worse in Europe, where pending laws might limit fees to a point where nobody could pay Apple the amount they get in the US.
Moreover, banks that have been using chip&PIN see no reason to pay Apple for implementing standards like EMV and tokenization.
I don't get it, there isn't actually any mention of what they are concerned about with "security"
Apple has explicitly stated multiple times that they do not collect customer info and have no interest in doing so.
For contactless purchases, Apple Pay collects location and time of purchase. I think they could use this to provide a map of Apple Pay compatible merchants. For in-app payments, Apple Pay collects app, merchant, amount, time info.
However, the banks are not worried about just the info that Apple directly collects. Apple also demands information
back from the banks. From a copy of an Apple Pay bank contract:
Beyond fees, the contract also requires issuers to produce, through the card network, an extensive set of statistics for Apple regarding their Apple Pay activity, including nearly three-dozen categories of quantifiable information.
Categories include number and dollar volume of credit and debit activity, average ticket, breakdown of transactions between in-store and in-app usage, and top 100 merchants by charge volume.
Digital Transactions
(When Apple says they don't collect info during a purchase, they're telling a truth, but not the whole truth. They're not collecting personalized or general purchase info themselves, but they're still getting tons of useful purchase information fed back to them.)
