Excerpt from Kevin103 post above that is the most relevant for IOU as they DO have a way to check all this for the underbanked or unbanked- that is one of their BIG advantages in the market

Perhaps the trickiest challenge is screening people who apply for credit. It has to be done fast. There are sweet spots to hit, as you want to include users who might not qualify for credit cards but are good risks nonetheless. Further, in a relatively greenfield market such as Southeast Asia, conventional screening gets tough. As noted, most countries don’t have credit bureaus generating US-style FICO scores. Many people have scant credit profiles anyway; many are unbanked or only recently banked.
