It's insane to me that CurrentC is even a "thing," when retailers could be doing MUCH better just supporting things like Passbook passes with QR codes/barcodes for customer loyalty programs and tracking of purchases for marketing purposes.
I personally think it would be great to have loyalty pass Passbook cards for retailers I want to share information with, for special offers, etc., and another set of passbook cards for credit cards using Apple Pay. That sounds slick. CurrentC is anything but slick.
