Digital transformation in the banking sector is a necessity. Over the past few years, demands for digital acceleration have become increasingly prominent, driven by changes in public expectations for fast, efficient, and secure financial services that can be done from anywhere. Such conditions require banks to place digital transformation as a priority and one of the strategies in an effort to increase the competitiveness of the Bank. Digital financial services in Indonesia have grown rapidly since the global financial crisis of 2008, leveraging innovation and new financial technologies to expand their reach and deliver new customer services. This service is growing rapidly due to the expansion of internet access; penetration of mobile phones, especially smartphones; big data analytics; and a range of new financial services providers from e-money and mobile payments to alternative finance platforms, including peer-to-peer (P2P) and other digital lending models. Digital financial services that complement traditional financial institutions are not seen as a nuisance and are instead seen as an evolutionary step. Big Data with its position as a key technology in the financial services industry needs clarity in matters including: certainty, security, conduct, consumer protection, and sustainability. These things need to be monitored by the regulator, between innovation and development as well as in terms of sustainability, stability, and consumer protection. For AI and Big Data to combine and bring out the best in their potential, machine learning needs to be factored in. Machine learning will require a large amount of data to train the system. The fact that most banking applications cannot process and retrieve large data sets can be overcome by utilizing one-time learning models that allow training of machine learning systems on smaller amounts of data. The financial services industry has experienced very rapid development, especially the existence of technology so that it needs to be studied and become knowledge for students and the community.
