OMR is capable of scanning the entire document within no time. It reduces manual efforts and the probability of human error to a great extent. It is also used in lottery tickets. In OCR, you design a system that analyzes the shape of the marks and then recognize the characters.
Thus, implementing OCR needs more complex hardware as well as a software system. The document is first scanned into image format. The individual marks on the image are then mapped to a known character set. Though there are still many who doubt the accuracy of OCR, it has many times proven itself to be quite worthy of being the go-to technology.

OCR also needs to determine what that mark is. It is usually limited to a single language to limit the possible characters and enhance the accuracy.
The primary purpose of OCR is to eliminate the need to re-encode a document that has already been printed. OCR takes an image of a printed document, attempts to recognize all the characters on a page, then string the characters together into an editable document that can then be edited in a word processor and mostly resembles the original document.
In comparison, the main use of OMR is in tabulating or evaluating data from a large number of documents. The biggest example of this is in grading simple multiple choice exams. OMR is also used to tabulate data from census or surveys using the same method. OMR is much faster compared to doing it by hand since the machine can process a sheet in an instant.
