Data Capturing through Scanning

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, such as PDF-417, 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. allows the encoding of alpha and numeric characters, whereas Code 2 of 5 Interleaved (known as code ITF) allows encoding of numbers only. Soft sys 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 companies 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.

Micro Film data need to be captured to computer format due to following reasons: Microfilm images are too small to read with the naked eye. Special readers are required to project full-size images on a ground-glass screen or a flat reading surface. A conventional photocopier cannot reproduce the images and a special combined scanner/printer is required. Libraries using microfilm often have a very limited number of these viewers that can produce a photocopy of an image, for a nominal fee. Shelf space is required to maintain an efficient archive as well as a safe and secure storage environment. Microfilms itself can only be reproduced a limited number of times, while digital media regenerate and often include error detection and correction schemes. Searching process is time consuming .

Thus data stored on Micro Films needs to be converted to computer format, so that data can be stored on the computers and databases to increase the life, safety and accessibility of data and productivity of the organization. Reduce storage cost of the data, so that staff deployed for storage and retrieval of data can be employed to some other productive functions of the organization. The silent feature of Soft sys Micro Films data capturing system are as: Using state-of-the-art scanners and image enhancement software producing images often better than the quality of the original film Facility to capture Micro Films data into documents or databases of client's choice Data caputred from MicroFilms is indexed and can be displayed with a simple keystroke and universally accessed via the Internet .
