Document imaging refers to the practice of converting information contained in physical documents into digital images with the use of scanners, special cameras and other electronic transfer processes. Document imaging is a vital part of Enterprise Content Management (ECM), widely used in business for replicating document. Number of document imaging system types include copiers, microfilms, scanners, facsimile machines, archive writers, multifunction printers and Computer Output Microfilm (COM) among others. Organizations that make use of document imaging technology have an edge over others in terms of reduction in paper usage, reduced record storage space, quick & easy access to information and improved information security among others. Similarly, such technology enables data duplication and transfer in digital format to create secure electronic backup media that can be stored off site as well.
