I think we're seeing two different things conflated in this article.
From APPLE'S point of view, presumably they have some sort of goal where they want people to use their payments system. (The end point is probably something like a Bank of Apple, where I'm essentially using the equivalent of an Apple credit card; but the system launched this year will probably be more like the existing iTunes system which is based on my current credit card).
OK, so Apple have a problem. It may be cool to use my iPhone, iWatch and fingerprint together to buy something BUT when I use my existing credit card I get 1% cash back. If Apple can't match that, they're not of any interest except occasionally to amaze my stupider friends.
Which means that one part of a Rewards system is that they need to give me something that I consider at least as valuable as 1% cash back (or airline miles or Amazon point, or whatever your credit card gives you). The obvious way to do this would be Apple points that I can spend in either the Apple store or the iTunes store.
Meanwhile there is the other side of the equation, the merchant side. Apple want to give merchants some incentive to go to the hassle of supporting the system. IF they can (more or less) guarantee less fraud and overhead, that may be compelling enough for some use cases (like internet shopping) that the product sells itself. For other purposes, you want an additional gimmick and that seems to be what this post is about. Apple can for example, say that if you partner with us, then using our payment system at your hotel users will earn double Apple points, which (presumably) steers users to the hotel chain --- but the hotel chain can only cash in if they're set up to handle Apple payments.
Again you're probably aware of this sort of gimmick if you read the fine print of your card closely. Especially if your card is one that pays you in airline miles, it probably has these sorts of double points agreements with hotel chains, restaurants, auto rentals, and other travel type businesses.

They've scrapped plans for iTunes Radio even in the US.
Expect a Beats radio at some point, I imagine.

(a) You mean mainframes? No, I don't remember that.
(b) A computer is what *I* say a computer is.
(c) Apple changed its official name on January 9, 2007 from Apple Computer Inc to Apple Inc. Why do you think they did that?
