Mobile money is an important phenomenon for the cause of financial inclusion in developing countries. The value and volume of both mobile money transactions and payment systems transactions have tredemously increased in Ghana. This study sought to investigate the adoption of mobile money by Ghanaians, using members of the University of Ghana Legon campus as case study. The study adopted questionnaires as the sole instrument for data collection. The findings reveal that dominant use of mobile money by the average mobile money user is to send or receive money. Also, most mobile money users do not use the service to access and deposit money to their formal financial accounts. This study recommends that stakeholders intensify the education on the use and benefits of mobile money to increase interest in the service and reduce mobile money fraud.
