You know, if "challenging the status quo" meant "improving consumer security and privacy", then I'd be wildly in support of CurrentC. If it was, say, roughly as easy as Apple Pay, and required a similar amount of information (that is, your account number and verification--not your SSN and probably direct access to your bank account, too), then it might not look so bad. And if they said, "Sure, use Apple Pay or Google Wallet, but once you try CurrentC, we're sure you'll prefer our service", then I probably wouldn't be nearly as offended by the other problems with the system.
But the reality is that the system may be challenging the status quo of credit card processing fees, it's also an assault on what little consumer privacy existed at the retail level to begin with (reading one of the articles on just how much the big national retailers know about you from tracking your purchases and buying additional information from brokers to fill out the picture is somewhere between impressive and terrifying), and it really only benefits the retailers, not the consumer, with the only way to push it being to remove the opportunity to use competitors, tells me all I need to know.
That makes them not just another player in the market that I may or may not use, but something I actively want to fail, and anything their CEO tells me pretty much assumed to be a lie.
So while MCX could have just been competition--which is good, particularly if it shakes up things and reduces systemic costs and lock-in--it's now, basically, an antagonist. It's already cost CVS and Rite Aid my business, and I even took the time to send a note to Sears telling them that I'd be taking my appliance purchases elsewhere on account of their participation. Guess I just really don't like being the product.
It might still succeed, who knows. And I'd love to see an actual alternative system like this that really did shake up the payment processing industry (a la PayPal, which has its own problems). I just hope MCX isn't it.
