The poorest people in the world (those on around $2 a day or less) mainly use cash. This is costly for them to handle and it’s costly for institutions to handle, meaning that they have less access to ways of handling shocks, exploiting opportunities, and managing risk.
Digital banking and payment systems and then financial products targeted at the poor built on those systems.
Gates Foundation, World Bank, CGAP, several tech startups.
GiveWell recommended charity GiveDirectly uses the M-Pesa mobile money system to do its cash transfers[^1] and altruistic startup Sendwave also uses M-Pesa to facilitate its no-fee remittance service. This tipped us off to the idea that a digital payments system could allow other promising projects to be built on top of it as well as the direct benefits of that payment system.
Also, financial systems are well suited to software solutions, as we can see in the developed world with e-banking and online payments.
Our investigation so far has consisted of reading introductory materials in the area, listed at the end.
The poor mainly use cash and usually don’t have a bank account.
Their use of cash is directly costly to them because it requires transportation and it is insecure. It’s indirectly costly to them because companies like banks pass on the cost of processing cash to their customers[^2]. The poor thus tend not to have access to the formal financial system and so are limited in how they can make payments and access loans and savings products.[^3]
The Gates Foundation has identified digitally-based financial tools for the world’s poorest as one if its goals.
The Consultative Group to Assist the Poor is “a global partnership of 34 leading organizations that seek to advance financial inclusion”.
AFI Global is “a global network of financial policymakers from developing and emerging countries working together to increase access to appropriate financial services for the poor.”
There are also companies and charities developing technology to solve this problem.
The World Bank paper The Opportunities of Digitizing Payments has a useful list of challenges for digital payments, many of which could have technical solutions.
Neglectedness: The presence of the Gates Foundation in this field suggests that it might not be very neglected. Also, there are already private companies working in this area, suggesting that the financial incentive will attract companies to solve these problems. We don’t understand the area in enough detail to spot specific subproblems that are more or less neglected.
Impact: We don’t have a good idea of what works and what doesn’t work in this area. For example, how beneficial is switching from cash to digital? Which financial products are most useful for the poor?

Handling cash transactions is costly for banks, utilities companies, and other institutions, which pass along the costs associated with storing, transporting, and processing cash to their customers.” [^3]: “The unbanked are people without formal bank accounts who operate in a cash economy; they are limited in their ability to take loans, maintain savings, or make remote payments (MEDHI & RATAN, 2009)” - Tobbin, Peter.

Communications & Strategies 86 (2012) [^4]: “So far the most successful deployment of transformational m-banking services is Safricom's M-PESA in Kenya (MORAWCZYNSKI & PICKENS, 2009). Since its launch in March 2007 it has been adopted by 11.7m customers (corresponding to 54% of Kenya's adult population and 73% of Safaricom's subscriber base). It processes more transactions domestically than Western Union does globally (MAS & RADCLIFFE, 2010). However, the success story of M-Pesa in Kenya has yet to be repeated anywhere else in Africa.” - Tobbin, Peter.
