As smart healthcare technologies emerge as pillars of modern medicine, developing policy and regulatory frameworks for sustainable financing becomes imperative. Regulatory complexities, spanning data governance, interoperability, and cost-effectiveness, present challenges and opportunities in securing funding for AI, IoT, and digital diagnostics. Policymakers must navigate privacy concerns, ethical dilemmas, and market dynamics to create resilient funding strategies. International cooperation plays a pivotal role in achieving SDG 3 by harmonizing funding protocols and prioritizing equitable access to advanced healthcare across nations. This chapter examines financial policy frameworks needed to support long-term technology integration in global health, exploring funding sources, cost management, and ethical imperatives. By addressing regulatory gaps, enhancing intergovernmental collaboration, and aligning technological investments with health equity goals, policymakers can foster a sustainable future where smart healthcare is accessible to all.
