This article discusses the development of FinTech in Indonesia, including its role in increasing financial inclusion, providing digital banking services, electronic payments, and peer-to-peer lending business models. Through literature analysis, this article shows that FinTech has driven significant changes in financial access and interactions, especially for those in remote areas or without access to traditional financial services.
