OMR or optical mark reader integrates optical technology and electronics to do data inputs hundred times faster than manual entry methods and is extensively used in multiple choice examinations ,statistics,data input etc
The OMR types depends on
1.The accuracy needed
eg;In case of a question with four options out of which one is to be made black using pencil, if an option is more than 75% blackened ,modern OMRs will read it while first generation OMRs wont.
2.The cost
3.The security and anti tampering of data
The main parts include an OMR scanner and an OMR sheet printer and a data entry and transfer software.
There are mainly 3 types of OMRs.
1.OMRFD
2.OMRFBS
3.OMRFBD
Different compnaies like NANHAO,DEVOSOFT,AXIOME produce different versions of the above said version which cna range to upto 40 types of Optical Mark Readers
The difference among the three types lies in
1.The nature and dimensions of paper used for entry n scanning
2.The number of photoelectric sensors used and its efficiency (2,4)
3.The number of reading done for a single sheet for added accuracy( twice,thrice)
4.The size of the machine and software used.(windows based,linux based)
5.The barcode used(128,39,25)
6.Operating temperature and other parameters
Optical Mark Reader (OMR) is a high-tech data input device integrated optical and electrical technology. It is a powerful tool for speedy automatic data capture, thousands of data bytes per second, several hundreds of times faster than manpower, especially it can work for a long time without break.
The input and output devices of a computer are normally abbreviated as I/O devices.There are a variety of input units,which are used by computers.THE MOST COMMONLY USED UNIT OF THIS TYPE IS A KEYBOARD AND A MOUSE OF A DESKTOP COMPUTER.Special purpose units are scanners,magnetic ink character reader,optical mark reader,optical character reader and bar code reader.
A special scanning device that can read carefully placed pencil marks on specially designed documents. This is an input device.

Optical Mark Reader. It is different from OCR.
Optical Mark Reader
An OMR (Optical Mark Recognition) is a scanner that reads the reflection of light from a specially designed design.
