TheStreet.com has picked up on the fact that many consumers are underserved by banks.  From the story: 

“More people are leaving banks. People are not being underwritten for credit cards, especially at the bottom end. And so the use of alternative financial services has increased significantly in the last few years,” says Arjan Schutte, senior advisor at the Center for Financial Services Innovation, a think tank for expanding access of financial services products to underbanked consumers.

“Even though remittances and check cashing volumes are stable as opposed to growing, there has been tremendous growth in payday loans and there’s been tremendous growth in more payroll agnostic, general purpose reloadable cards which can be used as a payroll card,” Schutte says.
