Document Imaging and Bar Coding Together Can Make Big Changes
Document imaging converts paper documents into a digital format. The digital documents need to be indexed to make them an integral part of the electronic workflow. Using barcodes that identify a document and the category under which it should be classified can speed up indexing.
The bar codes are attached to or printed on the paper documents. During scanning, the bar code also would be captured by the document imaging process. The information in the barcode would then be read and used by the indexing program.
For example, paper forms can be bar coded with information identifying the particular form and the class to which it belongs. When the form is imaged, the bar code information also would be captured.
When the digital form is filled in and saved, it would have the date information attached to it. The indexing program would thus have information about the particular form, its category and the date it was filled in. It might also have document author information. With this information it would be possible to create an index entry for that document.
Bar codes can be used even for facilitating the retrieval of paper documents. Where large numbers of original paper documents have to be stored, and retrieved quickly when needed, bar code stickers can be affixed to the documents, identifying each document by relevant information.
Using a bar code reader, selected documents (say in a particular storage location) can be quickly scanned and the needed document can be identified. There would be no need to go into the contents of the documents to identify the needed document.
Legal firms use this facility because they have to preserve original paper documents in large numbers. When a document is needed, they can take out the folder related to the particular case and identify the particular document quickly.
New Kinds of Bar Codes
Bar codes come these days in the traditional linear form and the newer matrix form.
Traditional barcodes represent each character by a vertical line. The lines are arranged horizontally across the paper. When the number of characters is about 30, these linear barcodes become too unwieldy.
The matrix, 2D, barcodes represent characters by small cells, arranged both vertically and horizontally. They can thus accommodate several times the number of characters that the linear barcode can.
It would be possible code complete information about a document using 2D barcodes. Not only indexing, but also other document related tasks, can be facilitated with this kind of coded information on each document.
Use of Barcodes in Document Management
Barcodes can be pre-printed on paper documents as an identifier, facilitating subsequent retrieval. The legal office example hinted earlier is an example.
Barcodes can also be pre-printed on separator pages to indicate the start and end of documents. This becomes useful when documents come in batches of sheets, as in a mailroom scenario.
Indexing of documents is facilitated by the bar code images and the identifying information they contain. A lot of information can be made available by 2D barcodes.
There are bar code generators that can speed up bar coding. With some input from the operator and from the application, generators can create relevant barcodes to be attached to the document.
Document imaging and barcodes together can speed up such document management tasks as indexing. Even paper documents can use bar codes for quick identification where needed. Bar codes these days come in the traditional liner and newer matrix format. The matrix 2D barcodes can accommodate much more information, like full document identifying and descriptive information.
