Document scanning

Data Capturing through Scanning capture data from books, magazines,newspapers and multipart forms through automated duplex high speed scanners. Source documents are properly de-staped, sorted, unfolded before scanning so all the data contained in the source document is properly scanned. After scanning the source documents,the documents are brought to the origanal shape by properly binding up the source documents.

Once the source document is scanned, the scanned data and original documents are throughly checked by Qality Control staff to ensure that All the pages in the source document are scanned Material contained in the source documents has been properly captured All the pages of the source document has been centered Captured images are of good guality.

Data Capturing through Barcodes There are many forms of barcodes although they can be separated into two types 1d and 2d barcodes. 1d barcodes, such as Code 39 or UPC, are the most common and are similar to the one shown above, where a single line through the barcode can read the code. 2d barcodes are rarer and more difficult to read as they are printed in two dimensions and require a full 100% horizontal and vertical scan of the area.

There are many ways of encoding a barcode known as a symbology. Symbologies are typically public domain and defined in specifications that define parameters such as the tolerences between bars, the patterns, the interleaving, the start and stop bar patters etc. One of the best resources for details of barcodes and their symbologies is found at barcode-1. The different symbologies determine what you can store within the code. For example, the Code 3 of 9 known as code 39 allows the encoding of alpha and numeric characters, whereas Code 2 of 5 Interleaved known as code ITF allows encoding of numbers only.

Softsys develop customised Stock management and Billing applications to capture data through Bar Code Reader. Such data capturing applications are useful as the data captured through Bar Code Readers increases the data entry speed and accuracy. Data Capturing from Microfilms Microfilms were used earlier by many compnaies and governments as an analog storage medium for books, periodicals, legal documents and engineering drawings.

Its most standard form is a roll of black and white 35mm photographic film. Another form, more common for engineering drawings, is a Hollerith punch card that mounts a single exposure. Most microfilm media have a digital indexing system exposed on the edge of each image, but these data are not required to use the microfilm, but rather to support automated retrieval systems.
