Mobile
phone-enabled banking and payments
Understanding usability,
security, social context, and impact
Overview | Research | Resources | Contact
The excitement around mobile phone-enabled banking
(m-banking) and payment (m-payment) channels is on the rise, and their
combination with the delivery of key financial services is believed to hold
much promise as a socio-economic development tool. However, there is a need for
systematic research to understand the relation between such innovations in
financial service delivery and poverty alleviation.
We are engaged in a four-part research project with
the objectives of:
·
Understanding user interface (UI) and user
experience (UX) design requirements for low-literate customers of m-banking and
m-payment solutions;
·
Designing secure technology solutions that
match these UI requirements;
·
Assessing the social and economic context
in which low-income individuals use m-banking and m-payment services;
·
Studying the effect of m-banking and
m-payment usage on the lives of low-income individuals, especially the impact on
economic welfare, social networks and cultural ties.
The project involves looking at a range of existing
and proposed m-banking and m-payment solutions across countries, understanding
the usability of m-banking systems by low-literate clients, as well as
assessing the social and economic context and impact of the new channel on
low-income households.

We are developing new technologies for doing authenticated banking on
developing world mobile networks. What makes this problem particularly hard is
the fact that a large number of mobile phones in the developing world have
limited computing capabilities and are essentially impossible to program with
software that one might want to use for strong security. (See picture.) Add to
this the fact that current-day GSM networks neither provide good privacy
guarantees to users nor enable secure authenticated communication between them.
To counter these problems, we have come up with novel user-hardware based
solutions for sending authenticated messages over mobile phones, similar to the
ones that are used in corporate access control systems. We are working with EKO, a mobile banking provider in India, on
this project. Our solutions have been field-tested with EKO’s customers and are
being considered for deployment.

Previous Research
The project’s field research has involved ethnographic
design methods, as well as interviews with key stakeholders (primarily
end-users of the service, channel mediators (e.g. agents), and the
institutional providers of the service) to collect data on the key constraints
targeted by the intervention, usage patterns of the m-banking channel, cost
comparisons between old and new channels for the given service, convenience
metrics, welfare impact, and the social networks involved in usage. Our
analysis presents an assessment of the strengths and weaknesses of the
m-banking channel in meeting goals of accessibility, usability, cost savings,
improved quality, convenience and social relevance in serving low-income
clientele and contributing to welfare gains.
Publications
Our research has involved field investigations in India, the
Philippines, Kenya and South Africa so far. Each field study has resulted in a
detailed case report, whose findings are then synthesized for public circulation.
