This research describes the implementation of Islamic banking digitalization and its challenges and opportunities. This study employs a qualitative research approach with a library research method. The implementation of digitalization in Islamic banking has significantly improved the efficiency, accessibility, and compliance of financial services with Islamic principles. The digitalization of Islamic banking in Indonesia is significantly transforming the financial landscape, making Sharia-compliant financial services more accessible, efficient, and secure. Through technological advancements such as mobile banking, AI, blockchain, and fintech innovations, Indonesia is strengthening its position as a global leader in the Islamic finance industry. By integrating mobile banking, fintech solutions, blockchain, AI, big data, and digital microfinance, Islamic banks can offer modern, Sharia-compliant financial services to a broader audience. However, continuous innovation and regulatory compliance are necessary to ensure that digital Islamic banking remains aligned with ethical and Islamic financial principles. From an Islamic perspective, digitalization in Islamic banking is seen as an opportunity to enhance financial accessibility, transparency, and ethical finance while adhering to Sharia principles. However, careful implementation is required to ensure that digital financial services do not contradict Islamic laws regarding riba, gharar, and maysir. By leveraging technology responsibly, Islamic banking can thrive in the digital era while upholding the values of justice, trust, and economic equity as prescribed in Islamic teachings. The digitalization of Islamic banking presents both challenges and opportunities. On the one hand, banks must overcome regulatory hurdles, cybersecurity risks, digital literacy gaps, and competition from conventional financial institutions. On the other hand, digitalization offers vast potential to expand accessibility, improve efficiency, foster financial innovation, and reach global markets. By embracing technological advancements while adhering to Islamic finance principles, Islamic banks can position themselves as key players in the future of digital finance. Through strategic planning and innovation, Islamic banking can bridge the gap between modern financial technology and ethical, Sharia-compliant banking solutions, ensuring sustainable growth in the digital era. The digitalization of Islamic banking offers significant opportunities for society, including increased access to financial services, ethical investment options, and greater economic participation. However, challenges such as cybersecurity threats, lack of digital literacy, and ensuring regulatory compliance must be addressed. By taking proactive steps to educate themselves, practice safe online banking, and support Sharia-compliant digital solutions, individuals and businesses can fully harness the potential of Islamic digital banking while upholding Islamic financial principles.
