Mobile Money
A system that provides basic financial services through mobile phone numbers, allowing users to transfer funds, make payments, and withdraw cash without a traditional bank account. Mobile money is a significant infrastructure for financial inclusion, particularly in sub-Saharan Africa, and its security and privacy properties have become a subject of human-centered research.

Mobile money is a system that provides basic financial services via mobile phone numbers, typically exemplified by Kenya's M-Pesa; users can deposit and withdraw cash, transfer money, and make payments at agent outlets without needing a traditional bank account.
The Minando team redesigned the mobile money process: users complete biometric or voiceprint authentication directly with the provider without showing ID to the agent; after the transaction, the user and the agent each receive the same one-time verification code, the user shows this code to the agent to complete verification, and the name and phone number are no longer transmitted to the agent.
Through paper prototypes and Wizard-of-Oz user testing, both users and agents preferred the new mobile money process, citing reasons including less exposure of personally identifiable information, perceived security of biometric authentication, and the convenience of not needing to carry ID documents.
The new mobile money process also exposed accessibility issues: some users' worn fingerprints make biometric authentication difficult, older users and those with lower technical literacy face operational barriers, and female interviewees expressed stronger concerns about agents obtaining their phone numbers.
