Data entry was once considered a dreadful job because it involved keying in of pages of data available as printed or typewritten documents. However, the same cannot be said now because after OCR technology was discovered, data entry has become as good as outdated. OCR, or optical character recognition is a means by which documents are first scanned using a scanner and then converted into a text searchable form. It is an alternative method through which data entry and form processing are carried out. An OCR engine has a database in which matches for the scanned data is present and the engine scans characters in the image and makes a replica of it in a word processor.
OCR engines are very difficult to operate manually. Hence, OCR software is used for the purpose. OCR software takes the image from the scanner as input and makes the OCR engine scan the document and then converts the image into a text searchable format. OCR engines cannot scan handwritten documents because the ink may be too thin or the handwriting may vary in styles and shapes, thus reducing the accuracy of the OCR process. OCR software are preferred because it allows batch processing and also enhances the accuracy of the OCR engine.
Free OCR is nothing but OCR software that is available for free. Free OCR is available all over the internet. It can be downloaded for extensive use or may even be used online for minimal use. Free online OCR is nothing but OCR engines which are loaded on an online server and the server obtains the image files from the users and converts the image files into text searchable files. Free OCR software is available for download in many sites too. The main advantages of using downloaded free OCR are that the information converted using OCR may not be copied without the knowledge of the user into the server which is possible in free online OCR. Free OCR is in no way lesser than paid OCR software. The accuracy, speed, language discrimination, data abstraction, data retention property and image replication property of all free OCR engines are nothing short of excellent.
