"$700 million worth of charges" Visa only gets 2-5% of the charge. Lets assume on the high end at 5% we are talking about only 35 million in income. Even doubling that for the second week we get 70 million (before costs). How is that the quickest ROI ever? Sounds like a bad marketing move backed up by a loss of profits. Maybe the real winners were the olympic committee or the other credit card companies that bid up the price against Visa.
Visa's in it for the interest payments. For every consumer that doesn't pay their bill in full each month ... they've got months and/or years of interest piled on top of paying back whatever they spent.
