This document discusses different types of data capture including fixed form, semi-structured, and unstructured data. It provides examples of each type and best practices for preparing documents and choosing a technology for data capture. The key types are fixed form for standardized forms, semi-structured for documents that have consistent field types but layout can vary, and unstructured for documents without consistent fields. Best practices include understanding the document types and business processes, setting realistic accuracy goals, and getting demonstrations on sample documents.
