Summary
This project investigates the viability of using a cellphone as a wallet.

Details
We investigate the viability of using a cellphone as a wallet. In particular, we use cellphones with near field communication (NFC) capabilities to perform peer-to-peer cash exchanges. We also use cellphones to store payment card details.

This project combines software development with rigorous usability testing of our prototypes.
