What is the difference between a 1D scanner and 2D scanner?

A 1D scanner uses laser or CCD linear LED’s to read a 1D barcode, whereas the 2D barcode is scanned via an 2D image capture. There are other differences including:

  • 1D barcode scanners cannot read 2D barcodes whereas the 2D barcode imager’s can read both 1D and 2D.
  • 2D imagers can read barcodes from a screen whereas the 1D cannot.
  • Laser scanners have a better tolerance for movement and distance.
  • Image scanners are better at reading barcodes at off-angles.
  • Image scanners are better at capturing dirty or damaged barcodes.
  • Laser scanners are generally a lot cheaper.

Which is better, depends on the application. In many cases where there is just a 1D barcode being scanned then a laser scanner is the most economical and reliable choice.
