OCR is a specific technology using which you can design software that can convert electronic data into an editable format. A tool that has been working on the basis of this technology recognizes the characters printed on a scanned document.

The OCR technology helps us a lot in sharing data easily with a few simple clicks. Optical Character Recognition (OCR) technology allows you to analyze handwritten scanned documents and then convert the data into digital text format.

This technology works by using different technologies and algorithms to convert printed data into editable digital text.

OCR technology has brought up a great revolution in today’s documentation and data sharing field. Everyone, from student to teacher, from businessman to a clerk, from bank to companies is getting benefit from this application today.

Uses of OCR technology

It is really hard to sum up the uses of OCR technology in a single article. Here we are going to discuss some major uses of this handy technology.

Students are mostly getting their notes, assignments, and other essential papers related to their syllabus in PDF format. It has become difficult for them to edit these documents to complete their assignments in time.

By using this technology, they can now convert the whole document into editable text and then make changes as they need.

Sometimes they get pictures of notes which are written in bad handwriting. In such cases, it looks tricky to understand what actually has been written on it. This technology is also beneficial in this regard as it can also scan these documents and convert the text into an editable format.

A student can easily then read and understands the topic written on these notes and make assignments easily. In turn, it has become easy for a student to get notes in any format and use them as per his requirements.

The students of higher classes often face a problem when they have to come across a book or notes which are not in their native language. As they are given a short deadline to complete and submit the thesis, they do not have much time to translate the whole book and then read it to make notes.

It is also impossible to type the complete book again and then translate it into a language that they can understand. In this case, a program based on OCR technology helps you a lot in completing the task within a few minutes.

You can take pictures of the whole book and then by using this technology extract the whole data into the editable text format. By copy-pasting that text, you can translate the book into your native language.

Now you are all set to read the book and make notes to complete your assignment in time. This technique is also used by businesses when they work worldwide. They can translate documents into their language and then can complete orders properly in time.

If you ever visited a government office or a place where documents are used in bulk, you have surely seen a bundle of files there. Do you really think it is easy to take care of these documents?

It will be very difficult to keep these documents in the proper condition. Secondly, it will not be an easy task to find an older document when needed. There is also the risk that documents may be lost often.

Optical Character Recognition technology makes it very easy to store documents in a small space where these documents are safe for years. With the help of this technology, you can easily convert these documents into digital files and then save them on any hard disk.

In this way, your documents will be safe for a long time. You can easily access any document whenever you need it by simply searching your database where you think you have saved them for later use.
