Detecting and reading barcodes are special features of the Addmen OMR software. Barcodes are useful when the examination board does not want the examiner to know the identity of the student. This ensures impartial evaluation and malpractices. It is also a convenient tool as you do not have to use a separate barcode reading machine to read the sheets. The software also reads the barcode as it processes the OMR forms and sheets. Addmen OMR software can also be used to design OMR sheets with barcodes.
Addmen OMR software has an inbuilt facility for designing OMR sheets.
You can design different types of OMR sheets including a variety of OMR answer sheets as well as OMR forms.
For creating barcodes for OMR answer sheets or forms, you have to provide a series of random numbers.
The software will automatically create a barcode for you (a group of thick and thin lines that represent a group of numbers).
Once the OMR sheets with barcodes are designed, you can get them printed.
You do not need any special printer for printing these sheets.
You can use a laser printer or inkjet printer that you normally use for printing.
The same applies for scanning these sheets. A normal scanner is sufficient for scanning the barcodes on the OMR sheets.
The OMR software reads the barcodes on scanned copies of the sheets
But if you take a photocopy of the original OMR sheet and then scan it, the resulting barcode scan won’t be properly identified by the OMR software; thus avoiding chances of malpractices
Barcodes are used in OMR sheets to conceal the identity of the student or person who is using the OMR sheet.
In case of OMR answer sheets, revealing the identity of the student through roll number or any other means can lead to malpractices at the time of checking.
As barcodes cannot be identified without the help of a device or software, such problems can be avoided.
Barcodes are also used in special purpose OMR forms like OMR feedback forms, OMR survey forms, OMR ballot papers, etc. where the individual does not want to reveal his/her identity.
The OMR software has several amazing features; designing and reading barcodes are some of the important ones. With the OMR software, you do not have to rely on any other tool, device or software for generating and detecting barcodes.
