OMR is an acronym for Optical Mark Recognition/Optical Mark Reader. OMR is now used for data entry. In the early’s OMR used two forms that were punched cards and paper tape which used actual holes instead of filling up the bubbles which we use in modern OMR.
When modern OMR came into existence it removed all the bugs and the pencil filled bubble was recognized through optical mark scanner which gives great accuracy.
Traditionally used technique for checking bulk sheets was very time consuming and was a headache to institutes. With the advent of OMR it has provided a great solution to institutes who take regular tests.
