Ok then going by your argument that MCX sole purpose is to cut out charges levied by banks and credit card companies,
I never said that. I have stated that that appears to be the big goal of it, and, for me anyway, makes this move to temporarily shut down NFC by some big, successful retailers make some sense.
then why do they need a lot of personal information on their customers? Why don't they forego collecting information on their users ?.
They don't need it; they
want it. "Know thy customer" is the first tenet of good marketing. Along with the nefarious uses of such information that we can spin, there are positive uses. They've shared the ideas of relevant coupons which could help customers save money. Lots of companies want to "know thy customer" better so that they can try to be more relevant to those customers.
That said though, I'm not a fan of that part of MCX but right now, that's only a part of the concept that may or may not make it to the finish line. If it makes it and the benefits of data are overwhelmed by the negatives of exploiting such data, people will choose not to use it. Lots of these same stores offer "rewards cards". Some consumers swear by them while others avoid them for this very same kind of thinking. If that part of MCX makes it into the final product, maybe MCX is only embraced by those who like sharing such data so that stores can give them benefits like those that come with toting around rewards cards.
To cut out 2-3% charges, they don't need all the personal information, do they?.
No they don't. That's 2 separate things.
I think bankers should do bankers job, retailers should do retailers job... If retailers cut out the bankers and credit card companies, then what, you want bankers to start opening retail stores so that they can maintain their profits?
For about the 20th time now, this is not about completely killing CC companies- just an alternative. We've had alternatives all along (we could pay with cash or checks or barter or layaway). Even if retailers desperately wanted to cut out bankers, they couldn't do it because some consumers won't be forced to change. And that's how it should be.
As for bankers feeling the pain of such an event, no I don't expect bankers to open retail stores. Bankers always find a way to make money. If this could be completely turned off today, they'd just turn up many other ways to make money. Even if a bunch of things worked against them at the same time such that they could all fail, the governments of the world will step in and "save" them at taxpayers expense.
My expectations of this if it does make it to market is that it will be an alternative platform for payment- like CC are now, like PayPal, etc. Software like Apple Pay and Google Wallet might be evolved to also work with it so that consumers can't even tell if it's MCX or "as is" or Paypal actually doing the transactional business behind the scenes. While Apple might refuse to support any data capture elements of MCX, Google would probably go right along and thus Android would adopt the underpinning platform. Then, Android could redo the old Visa (Android/Google Wallet) spin vs. American Express (Apple):
