Q:

How does an OMR scanner with hardware work?

A . Nov 27, 2023 A:

An OMR scanner with hardware works in the following way:

  • The scanner emits light onto the form
  • It recognizes the variation of the light’s reflectance at specific positions on the form and identifies the black marks as they reflect less light than blank spaces
  • The scanner’s computer software then recognizes the marks and converts the scanned images into computer-readable data
  • Reports with graphical and statistical representations are automatically generated by the software.

Q:

Do regular barcode scanners work with QR?

Mulchand dahre . Jun 15, 2023 A:

A standard barcode scanner cannot read QR codes because QRs consist of dots, squares, hexagons, and other shapes which are only read by 2D scanners. A regular barcode scanner is scanned by 1D scanners because they are made of only lines with different thicknesses.
