In bitfarm-Archiv Document Management a Batch Scan refers to the process of automatic and unattended scanning and archiving of large batches of documents. The batch need not only contain one type of document (e.g. invoice). For later retrieval the OCR runs a background process to extract the Full-text index. The (sometimes unsorted) documents get processed automatically according to specific characteristics – the Document Management System's technology can place several pages into one document as well as, depending on the type of document, automatically sort them into the corresponding archives all by itself. Tagging can also be automated according to a specific set of rules.
