Optical Mark Readers (OMR)

An Optical Mark Reader is a scanning device that reads carefully placed pencil marks on a specially designed form or document. OMR form

A simple pen or pencil mark is made on the form to indicate the correct choice e.g. a multiple choice exam paper or on the National Lottery ticket selection form.

The completed forms are scanned by an Optical Mark Reader (OMR) which detects the presence of a mark by measuring the reflected light. Less light is reflected where a mark has been made.

The OMR then interprets the pattern of marks into a data record and sends this to the computer for storage, analysis and reporting.

This provides a very fast and accurate method of inputting large amounts of data, provided the marks have been made accurately and clearly.
