The success or failure of MCX should be based on the facts, not FUD.
I don't believe my concerns about handing over ACH information or social security numbers is FUD. You clearly have a difference of opinion, and that's perfectly fine; hand over your bank account info to whomever you wish.
I simply prefer to have an additional barrier in place to protect myself against fraud. No matter how you slice it, credit cards offer that barrier. Unless and until MCX offers similar assurances, I personally won't be using them for that primary reason.
There will not be a mass clean-out of the bank accounts of MCX users.
I most certainly hope you're right. I suspect you are, but for different reasons: unless MCX significantly changes their business model and makes the payment process less cumbersome than unlocking your phone, launching an app and scanning some barcodes, I'm doubtful their uptake will be significant. And I doubt they will see mass adoption by consumers who would just as soon pull out a credit card (or use less-cumbersome NFC if the merchant permits it).
But all this is really off-topic in this thread ...
I think we can let the moderators decide what's on topic and what's not.
