Optical character recognition software: top five on the market

Digitising hard-copy documents made easy

Abby Finereader Pro

Optical character recognition (OCR) uses digital imaging devices and software to read text on hard-copy documents or in digital files that are rendered as images. The functionality can then be used to create digital, editable files.

The process can be used for a variety of purposes, such as scanning hard-copy forms or making PDFs editable, but it is perhaps most useful for businesses that use a lot of paper documentation or have a lot of historical documentation that needs digitising.

Without OCR, digitising hard-copy documents would be a manual process, with businesses employing individuals to input hard-copy data into a system. Not only is this time consuming and expensive, it has the potential for human error. OCR reduces the amount of human work required and therefore helps to minimise the cost of digitising documents. Over time, it has also become increasingly accurate and capable, meaning that errors are also minimised.

There are a variety of OCR packages available and they are pitched at different levels, and have different purposes. It's important, therefore, that businesses have a good idea of what they require from an OCR package before making any decision.

This article provides an overview of some of the most popular packages on the market. It gives a description of each and should provide a good starting point for businesses looking to purchase an OCR package.
