It's not a solved problem. 66% of the world does not have a bank account (much less a credit card).
However, 90% have access to a cell phone.

It didn't fail because of a lack of demand, but because it's hard to tackle without significant resources. I still might resurrect a less ambitious version (being a middleman here in Uruguay).
