A couple weeks ago I shared a prediction with James Governor, during a visit in his London office, that I thought a large bank or wireless telco would soon buy the other. It only makes sense. When you're using your cell phone to purchase a diet coke from a vending machine like they are in Japan, it isn't exactly visionary. Anyway, it hasn't happened yet, but James did just send me a link describing NTT DoCoMo's inquiry into buying a third of Mitsui Sumitomo Card, Japan's #2 credit card. This could get really interesting, though thanks to the vending lobby we still have to fight vending machines to take paper money here in the US, so maybe talks between Citigroup and Verizon are a bit off in the distance.
