What is Document Processing?

Document processing is the automated method of capturing, extracting, and managing information from physical or digital documents. Instead of manually entering data from invoices, forms, contracts, or receipts, document processing software uses technologies like Optical Character Recognition (OCR), Artificial Intelligence (AI), and Natural Language Processing (NLP) to read and process document data.
