Optical Character Recognition in Data Processing: Applications in Invoicing, Healthcare, and Financials

This paper examines the role of Optical Character Recognition (OCR) within modern data-processing pipelines, with a focus on invoicing, healthcare documentation, and financial records. It situates OCR as a foundational component of intelligent document processing systems, highlighting its impact on operational efficiency, data integrity, and regulatory compliance. The paper synthesizes academic literature and industry practice to analyze challenges, evaluation metrics, and architectural considerations for deploying OCR in regulated enterprise environments.
