Many countries seek to implement financial inclusion strategies because of their belief that access to financial services is an important step in reducing poverty and inequality, thus, achieving justice and reducing the gap between the poor and the rich, males and females. Despite this endeavor and efforts, formal financial institutions have limited ability to reach the poor and marginalized groups. Therefore, the aim of the research is to show the ability of financial technology (FinTech) as one of the innovations of the Fourth Industrial Revolution to connect consumers with financial services and achieve the advantages of saving, borrowing and transferring money. This financial access is via by simply opening mobile phone accounts in simpler and less expensive ways. Thus, the research clarified the ability of this model to reach the poor and marginalized groups and achieving justice in its income and gender aspects. The research used the inductive approach and descriptive analytical method based on the selected literature collection, in addition to the data of the Global Findex Database, and shed light on the experiences of India and Kenya as two pioneering experiences in this field, and study of the Egyptian case. The important conclusion is that financial technology can achieve justice and reduce the gender and income gaps, but it is not automatically and requires international and local efforts and procedures to take advantage of financial technology opportunities to serve the excluded and achieve justice.
