The US has over 6 million unbanked which are not necessarily poor. Some choose to be unbanked. I'm developing an app and network to help with this problem, It allows businesses to become ATMs where you not only withdraw cash but some could accept to reload an E-wallet which in turn would allow you to buy things online without a bank account. (maybe later we would launch a physical card) - DO you think it will work ?
Nope. Businesses can and do already reload value cards (including prepaid debit cards) which allow (among other things) buying online without a bank account, and it hasn't solved the problem.
