Anyone know what a "google voice" for credit cards is meant to mean?
A proxy card that is actually backed by various real credit cards. Automatically switching your balance across the optimum set of deals? This is kind of like what Simple.com do, except with credit.
BTW, from what I've read of Bank Simple, this isn't what their model is. From their FAQ - "Can I use Simple with my current bank? No. Through your relationship with Simple, your money is held in an FDIC-insured account at one of our bank partners."
