OMR software is image based OMR solution where a normal scanner is used for scanning OMR sheet and software is used to process the image to get the OMR fields data.
OMR software can capture OMR/OCR/ICR/Barcode/selective image area from the form.
The OMR software can read traditional OMR scanner sheet and normal printout too. Though some software has limitations, so choose after seeing the trial version only.
The scanner used for scanning OMR sheet can be a from flatbed to ADF (Automatic Document Feeder) scanner, ADF scanners are more preferred as they take less time and are more convenient to use. The other advantage is we can scan OMR sheets on any scanner and process them afterwards on one single computer.
